Abstract:
Abstract Metal halide perovskites have emerged in recent years as promising photovoltaic materials due to their excellent optical and electrical properties, enabling perovskite solar cells (PSCs) with certified power conversion efficiencies (PCEs) greater than 25%. Provided radiative recombination is the dominant recombination mechanism, photon recycling – the process of reabsorption (and re-emission) of photons that result from radiative recombination – can be utilized to further enhance the PCE toward the Shockley–Queisser (S-Q) theoretical limit. Geometrical optics can be exploited for the intentional trapping of such re-emitted photons within the device, to enhance the PCE. However, this scheme reaches its fundamental diffraction limits at the submicron scale. Therefore, introducing photonic nanostructures offer attractive solutions to manipulate and trap light at the nanoscale via light coupling into guided modes, as well as localized surface plasmon and surface plasmon polariton modes. This review focuses on light-trapping schemes for efficient photon recycling in PSCs. First, we summarize the working principles of photon recycling, which is followed by a review of essential requirements to make this process efficient. We then survey photon recycling in state-of-the-art PSCs and propose design strategies to invoke light-trapping to effectively exploit photon recycling in PSCs. Finally, we formulate a future outlook and discuss new research directions in the context of photon recycling.

Abstract:
The strength of recombination radiation reabsorption in GaN is discussed. For material comparisons a distance-dependent radiative recombination transfer function F(u) is introduced. In spite of high absorption rates of GaN, calculations predict ca. one order of magnitude higher photon recycling efficiency in GaN than in GaAs. Simulations of 2H-GaN p −i −n structures predict appearance of S-shaped forward I/V characteristics due to the generation of extra carriers in the base center. The study of GaN bipolar transistors shows that the radiative recombination will reduce the carrier lifetimes in the base and thereby restrict essentially the achievable current gains.

Abstract:
Approved for public release; distribution is unlimited.
The goal of this research was to use Monte Carlo simulations to further develop the model that describes transport imaging by including a more realistic description of the generation region created by the incident electrons. Monte Carlo simulation can be used to determine the energy distribution in bulk materials due to the interaction with incident electrons. In the simulation, the incident electrons undergo both elastic and inelastic scattering events. Through these events, the energy of the electrons is transferred to the target materials. This deposited energy can generate electron-hole pairs and then, via recombination, photons. In the experimental work, these photons are measured by a CCD camera connected to an optical microscope in a scanning electron microscope (SEM). Monte Carlo simulations were performed for a range of target materials and compared to the luminescence distributions measured experimentally. The simulated energy distributions are always spatially narrower than the optical image from the SEM. We propose possible explanations that need to be evaluated: the relationship between deposited energy and final electron distributions in the target material and photon recycling, in which locally generated photons are reabsorbed to produce a wider luminescence distribution. Further experiments are proposed to identify the limiting factors determining the minimum luminescence distribution.

In this thesis, we proposed and demonstrated a novel structure to perform photon recycling for a double-light-source illumination system pumped by a laser. In the design, a phosphor layer is located at the first focus of an elliptical reflective surface, which is used to recycle the backward scattering light and refocus at the other phosphor layer at the second focus. The absorption spectrum should fit that of the emission light by the first phosphor. When the emission spectrum covers infrared light, the whole system is a double-light-source for white light and infrared light. In order to apply the proposed structure to automotive headlamp, we have optimized the structure by considering the ellipticity. Thus we evaluated various designs based on the proposed structure.

In recent years, scientists have noted that the theoretical efficiency limit of solar cells can be largely affected by internal photon coupling and recycling effects. Therefore, light management has become an important issue for III-V and other solar cells made of direct bandgap materials. In this work, we employ multiple quantum well (MQW) solar cells with a high spontaneous emission rate to study the impact of photon recycling on the photovoltaic characteristics via the incorporation of Bragg mirrors and frontal selective filters. First, before the deposition of selective filters, the MQW solar cell with a Bragg mirror exhibits a lower open-circuit voltage (Voc) and fill factor (FF) than that without the mirror under one-sun illumination. However, the Voc is increased by 7.3 mV under 200 suns, compared to the reference, which is ascribed to the photon recycling effect via the back reflector. However, the fill factor is decreased significantly due to an increased series resistance, which arises from charge transport across the reflector composed of 10 dielectric pairs. Next, in order to suppress the spontaneous radiation losses toward the front surface, we deposit selective filters made of alternative titanium dioxide (TiO2) and silicon dioxide (SiO2) dielectric stacks, designed at cutoff wavelengths of 880nm, 910nm, and 930nm.The electroluminescence measurement confirms that light emission from the cell is inhibited by the filter, which in turn can lead to internal photon recycling. After incorporated with the selectivity filters, the MQW solar cells, with or without a back reflector, show enhanced Voc and FF compared to the reference counterpart without the filters, offering solid proof that suppress of spontaneous emission to increase photon recycling can effectively boost the photovoltaic characteristics. Moreover, the MQW solar cell with a Bragg reflector and selective filter at the 910nm cutoff wavelength exhibits a maximal Voc enhancement ~ 11mV. However, the FF enhancement is relatively small compared to other cutoff devices. We think that although photon recycling can improve the FF by reducing the probability of non-radiative recombination to increase carrier lifetime, the high carrier concentrations inside the cell is accompanied by the large series resistance; thus limit the FF improvement. Finally, although the FF is deteriorated by the increase of illumination concentration, the incorporation of selective filters can slow down the degradation due to photon recycling. This effect is particularly manifested for the MQW solar cells with both a Bragg reflector and selective filter.

In this thesis, we utilize blue laser diodes as light sources to excite yellow phosphor and enhance output power and efficiency for phosphor-converted white light laser lighting. We started from following the phosphor optical model developed in the laboratory led by Dr. Ching-Cherng Sun to analyze the optical characteristic of yellow phosphor applied on blue laser diode. Second, we designed a hemisphere reflector to perform photon-recycling to increase the optical efficiency of the system setup. In addition, the experimental measurement was compared with the simulation with the phosphor model. Finally, we designed angle-multiplexed laser injection to linearly increase the output flux with holding the étendue of whole system. Finally, we reduced the angular correlated color temperature deviations of the laser light source module with use of various diffusers.

In this thesis, we investigated the optical and electrical characteristics for photon-recycling structure light-emitting diodes (PRSLEDs). Comparing to conventional vertical light-emitting diodes (VLEDs), PRSLEDs had an additional multiple quantum well (MQW) converter above the device structures. Electrical characteristics of devices were analyzed by semiconductor parameters measurement, which demonstrated that PRSLEDs had better electrical performances compared to VLEDs. Because the MQW converter layer stacked on devices could reduce the strain-related stress of epitaxial structure. Then, the structure quality was improved and the crystal defects density decreased. While optical characteristics were analyzed by applying the Gaussian function fitting data of electroluminescence (EL) measurement. It showed that efficiency droop of electrically injected near ultraviolet (n-UV) light of PRSLEDs were improved, for its crystal quality was better than VLEDs aforementioned. Optically pumped blue/green light of PRSLEDs also showed potentially insignificant efficiency droop compared to direct blue/green VLEDs, for the volume of active region was increased by optical pumping mechanism, which reduced Auger recombination, carriers leakage, current crowding, and devices thermal effect, etc., effectively. In conclusion, the design of photon-recycling structure could improve LEDs electrical properties and effectively remedied efficiency droop of blue/green light by replacing the electric injection with optically pumped mechanism.

Abstract:
abstract: GaAs-based solar cells have attracted much interest because of their high conversion efficiencies of ~28% under one sun illumination. The main carrier recombination mechanisms in the GaAs-based solar cells are surface recombination, radiative recombination and non-radiative recombination. Photon recycling reduces the effect of radiative recombination and is an approach to obtain the device performance described by detailed balance theory. The photon recycling model has been developed and was applied to investigate the loss mechanisms in the state-of-the-art GaAs-based solar cell structures using PC1D software. A standard fabrication process of the GaAs-based solar cells is as follows: wafer preparation, individual cell isolation by mesa, n- and p-type metallization, rapid thermal annealing (RTA), cap layer etching, and anti-reflection coating (ARC). The growth rate for GaAs-based materials is one of critical factors to determine the cost for the growth of GaAs-based solar cells. The cost for fabricating GaAs-based solar cells can be reduced if the growth rate is increased without degrading the crystalline quality. The solar cell wafers grown at different growth rates of 14 μm/hour and 55 μm/hour were discussed in this work. The structural properties of the wafers were characterized by X-ray diffraction (XRD) to identify the crystalline quality, and then the as-grown wafers were fabricated into solar cell devices under the same process conditions. The optical and electrical properties such as surface reflection, external quantum efficiency (EQE), dark I-V, Suns-Voc, and illuminated I-V under one sun using a solar simulator were measured to compare the performances of the solar cells with different growth rates. Some simulations in PC1D have been demonstrated to investigate the reasons of the different device performances between fast growth and slow growth structures. A further analysis of the minority carrier lifetime is needed to investigate into the difference in device performances.
