Perovskite organometal halide based solar cells have recently attracted substantial attention due to high power conversion efficiency and ease of processing. Their photovoltaic performance is significantly affected by perovskite film morphology and uniformity regardless of the deposition method. To compare the performance of perovskite solar cells prepared by different solution-based deposition methods...
Substrate CdTe cells are uncommon due to the difficulty in forming effective contacts to p-type CdTe. The development of such solar cells could further increase the applications and enhance the product characteristics of the lowest cost thin film PV technology, by making lightweight and flexible products possible. This paper reviews the current status of the development of substrate CdTe solar cells...
Following our previous study on the material-quality limiting factors of evaporated solid-phase crystallized (SPC) poly-Si thin films fabricated on planar glass for photovoltaic applications, we extend our study to investigate the impurity levels, optical properties, transport properties, and device performance of so-called ??EVA?? (EVAporated Si) solar cells. These potentially cost-effective cells...
We fabricated glass/SnO2/CdS/CdTe samples with 100-nm-thick CdS by chemical-bath deposition and 8-mm-thick CdTe by close-spaced sublimation. A CdCl2 heat treatment was done in the presence of CdCl2 vapor at 400??C for 5 min. Our photoluminescence (PL) mapping is a direct-imaging technique in which the entire two-dimensional sample surface is imaged onto an electron-multiplying-CCD camera. PL at 850...
