Ag plasmonic nanostructures and a novel gel electrolyte in a high efficiency TiO2/CdS solar cell

We employed ultra-violet (UV) light treatment on the TiO2 layer prior to coating the perovskite layer to improve the solar conversion efficiency of perovskite solar cells (PSCs). A laboratory-made UV treatment system was equipped with various UV light sources (8 W power; maximum wavelengths of 254, 302, and 365 nm). The UV light treatment improved the power conversion efficiency (PCE) while coating the uniformity layer and removing impurities from the surface of cells. After the PSCs were exposed to UV light, their PCE developed approximately 10% efficiency; PBI2 decreased without changing the structure.

Solar Conversion Efficiency

Nanoporous and macroporous structures were prepared by using self-assembled monolayer (SAM) onto ZnO thin films in order to investigate the efficiency of dye-sensitized solar cells (DSSCs) produced using these films. Using SAM on ZnO thin films, it is obtained successfully assembled large-area, highly ordered porous ZnO thin films. Varying nanoporous radius is observed between 20 and 50 nm sizes, while it is 500–800 nm for macroporous radius. The solar conversion efficiency of 2.75% and IPCE of 29% was obtained using ZnO nanoporous/N719 dye/I−/I3-electrolyte, while macroporous ZnO given solar conversion efficiency of 2.22% and IPCE of 18%.

Carrier Extraction

ABSTRACTThin film microcrystalline silicon solar cells with absorber layers of various structural composition have been prepared. The highest conversion efficiency is observed at preparation conditions close to the transition to the amorphous growth regime, i.e. crystalline volume fraction is high but not at its maximum. The optimized material consists of crystalline “fibers” with small diameter which extend through the whole absorber layer. On further approach to the transition regime a set in of amorphous growth can be observed, resulting in decreasing solar cell performance. Surprisingly, material prepared under conditions favoring highly crystalline growth exhibits a less efficient carrier extraction if applied to the solar cell. We discuss increasing bulk recombination as possible cause for this observation. The maximum conversion efficiency obtained was 8.7 % for a 1 νm single junction solar cell. Using our optimized deposition conditions with simultaneously higher discharge powers the deposition rate can be increased up to 4.6 Å/s at the high efficiency of 8.3 %.
