Abstract
Optical properties are essential in the detailed design of modern perovskite-based solar cells (SCs). In fact, metal halide perovskite semiconductors offer rapid and easy manufacturing of good absorbent layers at low costs with such good optical performances as tunable band gaps, high optical conductivity and also high optical absorption. This is why these semiconductors are ideal candidates for the application of SCs. The two new perovskites (CH3)(2)NH2CdCl3 and CH3NH3CdCl3 were successfully investigated. Moreover, their optical properties are discussed in the present work. This study would present a suitable way to realize good competitors in efficient solar cell devices thanks to their superior properties including high optical absorbance, small band gaps and high optical conductivity. These findings play a major role in the study of ACdCl(3) (A is methylammonium (MA = CH3NH3) and dimethylammonium (DMA = (CH3)(2)NH2)), optical properties as well as the further fabrication of solar cell devices.
