Abstract:

Low-dimensional perovskite solar cells (LD PSCs) are a new type of stable and hydrophobic perovskite photovoltaic device, which have attracted broad interest in the field of renewable energy. In this experiment, focusing on the advanced development of LD PSCs, butylammonium and cysteamine (2-Amino-3-mercaptopropionic acid, Cys) are employed as organic spacer cations to synthesize LD perovskite crystals, and (BA)2(MA)n−1PbnI3n+1 or (Cys)2(MA)n−1PbnI3n+1 is used as the active layer to fabricate PSCs. Detections of X-ray diffraction and UV-Vis absorption spectroscopy are employed to characterize the morphology and optical properties of the perovskite film. Finally, the power conversion efficiency of the LD PSCs is measured. The difficulty of this experiment is moderate, involving in the fabrication and characterization of photovoltaic devices. This designed experiment aims for stimulating undergraduates' interest on the cutting-edge optoelectronic research and cultivate their scientific research ability.
