Abstract
Halide perovskite solar cells have shown the possibility for replacing silicon solar cells due to their potential increased performance, and low cost fabrication. Halide perovskite compounds include an ABX3 compound; where ‘A’ and ‘B’ are cations and ‘X’ is an anion. The perovskites are layered between hole or electron transport layers with a conducting material as the final layer. The cells fabricated in this study are layered as follows: indium tin oxide coated glass, titanium di-isopropoxide bis(acetylacetonate), methylammonium lead tri-bromide, titanium dioxide, and silver paint. Each layer, with the exception of the silver paint, was spin-coated onto the glass substrate. The competitive power conversion efficiencies, current output, of these perovskite solar cells were tested under a direct, intense light source on a NI Elvis board with supplementary programs. While tandem perovskite-silicon solar cells currently lead the field in a 25% efficiency rate, stand-alone perovskite cells still hold a greater appeal due to their extended lifetime, durability, and low cost.
