Abstract:

Solid-state dye-sensitized solar cells (ssDSSCs) and recently developed perovskite solar cells (PSCs) have attracted a great attention in the scientific field of photovoltaics due to their low cost, absence of solvent, simple fabrication and promising power conversion efficiency (PCE). In these types of solar cell, the dye molecule or the perovskite can harvest the light on the basis of electron excitation. Afterwards, the electron and hole are collected at the charge transport materials. Photoelectrochemical polymerization (PEP) is employed in this thesis to synthesize conducting polymer hole

Abstract:

The solid-state mesoscopic solar cells (sMSCs) have been developed as a promising alternative technology to the conventional photovoltaics. However, the device performance suffers from the low hole-mobilities and the incomplete pore filling of the hole transport materials (HTMs) into the mesoporous electrodes. A variety of HTMs and different preparation methods have been studied to overcome these limitations. There are two types of sMSCs included in this doctoral thesis, namely solid-state dye-sensitized solar cells (sDSCs) and organometallic halide perovskite based solar cells. Two different

The rapid development in perovskite solar cells (PSC) has generated a tremendous interest in the photovoltaic community. The power conversion efficiency (PCE) of these devices has increased from 3.8% in 2009 to a recent certified efficiency of over 20% which is mainly the product of the remarkable properties of the perovskite absorber material. One of the most important advances occurred with the replacement of the liquid electrolyte with a solid state hole conductor which enhanced PCE values and improved the device stability.

Abstract:

Electronic circuits comprising organic semiconductor thin-films are part of promising technologies for a renewable power generation and an energy-efficient information technology. Whereas TV and mobile phone applications of organic light emitting diodes (OLEDs) got ready for the market awhile ago, organic photovoltaics still lack in power conversion efficiencies, especially in relation to their current fabrication costs. A major reason for the low efficiencies are losses due to the large number of charge carrier traps in organic semiconductors as compared to silicon. It is the aim of this thes

A defect band is formed in hydrogenated amorphous silicon nitride (a-SiNx:H) due to current stressing of the material.

This thesis investigates the current transport mechanisms that occur in the induced defect band, by comparing the temperature dependence of the conductivity of several sets of a-SiNx:H thin film diodes. These sets were systematically current stressed to different levels with one set remaining unstressed. Samples with energy gaps of 2.06 eV and 2.28 eV were considered. We show that arou

The hydrogen bond renders physical cross-link between polymer main-chains and escalates materials’ thermal stability, and electro-chemical stability. Physical cross-links make polymer film less eroded and increase the possibility of the exercise on the multi-layer of PLED devise. In addition, the hydrogen bond brought by side-chain’s functional group reduces the distance bet

Especially, the time and budget cost of HTMs (Hole Transport Materials, HTMs) is considerable, therefore this situation leads that many scholars develop and find alternative materials to replace it. My research focuses on how the HTMs including AI104, AI107 applied on normal PSCs and measures the corresponding’s optical characteristics. These materials are small molecule compounds which can be used to repla

The HOMO energy levels of TAATZ 1-4 were about -5.4 eV and the LUMO levels were from -1.7 eV to -1.9 eV. Unstable radical cation of TAATZ-4 was showed because of its lack of electron donor group. The methoxy group reduces the formation of crystallization.

In this study, the new method for solution process of PTC-U increase the solvent resistance of PTC-U and make the trilayer device to be 1.8 times higher than the commercial product PEDOT:PSS-based devices. Most of all, we still prove that physically cross-linked structure is important for HITM. In addition, we successfully synthesized a thermal-cross-linked HITM, poly(fluoren-carbazol-benzoxazine) (PFC-Bz) which has good thermal, electronic propert

abstract: The inexorable upsurge in world’s energy demand has steered the search for newer renewable energy sources and photovoltaics seemed to be one of the best alternatives for energy production. Among the various photovoltaic technologies that emerged, organic/polymer photovoltaics based on solution processed bulk-heterojunctions (BHJ) of semiconducting polymers has gained serious attention owing to the use of inexpensive light-weight materials, exhibiting high mechanical flexibility and compatibility with low temperature roll-to-roll manufacturing techniques on flexible substrates.
