Abstract:

<p> Organic photovoltaics (OPV) offers a potential for solar-electric power generation to be affordable. Crucial to OPV device performance is the incorporation of interlayers, ultra-thin films deposited between the photoactive material and the electrical contacts. These interlayers have various, targeted functionalities: optical window, encapsulation, or electronic bridge. The last category is known as "transport layers'', and is the focus of this thesis. </p><p> In this thesis, we explore and investigate the physics that leads to improvements in OPV device performance when a transport laye

Abstract:

This research presents thin film deposition and characterization of metal oxides using industrially viable Physical Vapour Deposition (PVD) techniques. The research examines low temperature processed electron and hole transport metal oxides for high performance and stable perovskite solar cells. The physical, chemical, optical and electronic properties of the films were investigated and their device performance has been evaluated. The performance of the device improved and the materials cost reduced by replacing the expansive organic materials with more stable inorganic metal oxides.

Scanning electron microscope and atomic force microscope show the PbSe QDs films incorporating an organic PEDOT:PSS hole transport layer become smoother than the PbSe QDs films without PEDOT:PSS layer.

To fabricate the photodetector, the CuSCN hole transport layer was covered with a nanocomposite active layer followed by evaporating BCP as a hole block layer, and a sputtered aluminum film as the electrode. The active layer consists of a P-type organic PVK material and a N-type wide band-gap ZnO nanoparticles. When the device un

First, CuAlO2 was sintering to a powder and added to the precursor of PANI to prepare a thin film by spin coating. The solar cell structure is ITO/PANI+CuAlO2/CH3NH3PbI3/C60/BCP/Al. In this study, the surface morphology of the film was controlled by changing the ratio of addition. It was found that a PANI thin film add to 0.1 wt% of CuAlO2 powder had a 0.81 V open circ

In this study, a perovskite based solar cell device has been proposed and the power conversion efficiency, fill factor, open circuit voltage and short circuit current density of the proposed device was analyzed. When simulated, it achieves a power conversion efficiency of over 14% with AM 1.5 illumination. This type of perovskite solar cell has shown potential towards achieving a low cost and efficient solar energy conversion method and unlike its silicon counterparts, it has none of the disadvantages that are present in silicon based solar cells.

It is extremely important to develop high-quality hole transport layer (HTL) to replace PEDOT:PSS for fabricating inverted perovskite solar cells (PSCs) with high power conversion efficiency (PCE) and device stability.
