Abstract:

Among all the material parameters of a semiconductor, the lifetime of the carriers is one of the most complex, as it is a function of the dominant recombination mechanism, the number of carriers, the structural parameters and the temperature. Nevertheless, the lifetime of the carriers is a very useful and fundamental parameter to be determined for the qualification of the semiconductor in order to allow the improvement of the manufacturing process and the optimization of the operation of the semiconductor device. Thus being strongly linked to many physical and electronic parameters, the lifeti

This paper reports on the influence of temperature on the electrical carrier lifetime of a 3.3 kV 4H-SiC PiN diode processed with a new generation of SiC material. The Open Circuit Voltage Decay (OCVD) is used to evaluate ambipolar lifetime evolution versus temperature. The paper presents a description of the setup, electrical measurements and extraction fittings. The ambipolar lifetime is found to rise from 600 ns at 30 °C to 3.5 μs at 150 °C.

The reverse and forward currents of Al+ ion implanted 4H-SiC p+-i-n diodes have been compared for identically processed devices except for the implanted Al concentration in the emitter, 6×1019 cm-3 against 2×1020 cm-3, and the post implantation annealing treatment, 1600°C/30 min and 1650°C/25 min against 1950°C/5min. The diodes’ ambipolar carrier lifetime, as obtained by open circuit voltage decay measurements, has been compared too. The devices with lower annealing temperature show lower leakage currents and higher ambipolar carrier lifetime; they also show lower current in ohmic conduction.

Abstract:

Sharp avalanche breakdown voltages of 12.9 kV are measured on PiN rectifiers fabricated on 100 µm thick, 3 x 1014 cm-3 doped n- epilayers grown on n+ 4H-SiC substrates.

Specifically, when supercapacitors with 14 M LiCl electrolyte are charged to 0.80 V, the open circuit voltage (OCV) drops to 0.65 V in 24 h.

In addition, studies rarely report this kind of durability in real decay scenarios.

The key material and device parameters governing the electrical performance of high voltage 4 H - SiC PiN diodes have been investigated using experimental results and numerical simulations. Reverse recovery characteristics show an increase in both carrier lifetime and anode injection efficiency at elevated temperature. Open circuit voltage decay measurements are used to estimate carrier lifetimes (τ≈0.6μ s at T =25° C increasing to τ≈2μ s at T =225° C ) that are comparable to values measured on starting material prior to fabrication using micro-wave photoconductivity decay techniques.

Abstract:

Electrolyte imbalance in Redox Flow Batteries (RFBs) is known to result in significant capacity decay over cycling [1]. This drawback is inherent to the flow battery technology and is caused by unwanted physico-chemical phenomena, such as species and water crossover, hydrogen evolution, air oxidation and precipitation of vanadium ions. The time evolution of electrolyte imbalance is often disregarded or underestimated when measuring the open-circuit voltage (OCV) for keeping track of the battery State of Charge (SOC). In order to correct such asymmetry, in operando real-time monitoring of the S

<strong>ABSTRACT</strong> This work consists in studying the transient voltage of a silicon solar cell with vertical junctions connected in parallel under polychromatic illumination and under the influence of temperature and magnetic field, in open circuit transient operation. The experimental device of the transient decay who occurs between two operating points in steady state is presented. The effect of the potential difference between two operating points on the voltage amplitude is also studied. Indeed, the influence of the optimum temperature on the transient decay and on the amplitude of

Abstract:

Experiments are performed on solar cells under concentrated sunlight in order to explore fundamental physical processes with high injection conditions. Saturation effects are observed on the cell open circuit voltage and on the extracted values of the recombination current. A large decrease of the initial decay of the transient voltage have been measured. High injection effects are shown to be correlated with the increase of recombination current in the space charge region together with an increase of the emitterbase coupling.

Abstract:

This paper studied the impact of silicon oxide layer on photovoltaic characteristic of iron-doped amorphous carbon film/silicon heterojunction (a-C:Fe/Si). The results show that a native SiO2 layer on the silicon surface can provide a significant improvement of the a-C:Fe/Si devices’ photovoltaic performances, especially for the short circuit current and fill factor. This improvement partly may be attributed to the electron recombination process is suppressed and the interface is modified by the SiO2 film based on the open circuit voltage decay measurement.

Abstract:

Organic photovoltaic cells were fabricated by sandwiching p-toluene sulfonic acid doped conducting polymer polypyrrole between indium-tin-oxide cathodes and aluminum anodes. The active polymeric layers could effectively absorb incident photons more than 75 % in the entire spectral region of 250~1100 nm. Upon light exposure, the short-circuit current and the open-circuit voltage were recorded up to 0.6 μA/cm2 and 60 mV, respectively, for the organic photovoltaic cells. The dynamics of the generation and decay of the photocurrent and photovoltage in our organic photovoltaic cells were investigat
