Abstract:
Compact layer (CL) with pinhole-free and excellent electron conductivity is critical in high-efficient scaffold-type perovskite solar cells. In this study, we thoroughly investigated electrodeposited TiO X (ED-TiO X ) on FTO glass from aqueous TiCl 3 solution including the kinetics of the electrodeposition, film morphology, optical and electronic properties. Furthermore, by controlling the total charge amount, the thickness of ED-TiO X films as well as device performance are tunable. When applying this method to fabricate the CL for scaffold-type perovskite solar cells, we compared the hole blocking effectiveness, charge extraction capability and photovoltaic performance of TiO 2 CLs made by electrodeposition and other common methods such as dip coating (DC), spin coating (SC) and spray pyrolysis (SP). Current results reveal ED-TiO X CL performs best for its full coverage, thinnest thickness and mossy surface, rendering high shunt resistance and low ohmic resistance. In addition, our results also confirm in scaffold-type perovskite solar cell configuration, CL still provides charge extraction function in addition to the mesoporous scaffold. The device using ED-TiO X CL currently shows highest power conversion efficiency (PCE) up to 15.48%. Figure 1
