Abstract

Hybrid organic-inorganic halide perovskites solar cells (PVSCs) have made great progress in just a few years. With maximum efficiencies evolving from 3.8% to 22.1%. The ongoing efficiency improvements are obtained mainly through the optimization of material process and the enhancement of interface. Whereas the conflict between generating photo carriers and collecting carriers is still a challenge for PVSCs. Light trapping design provides a promising way to solve the problem. However, there are few reports about light trapping effect in PVSCs. In this contribution, FTO substrates with different texture etched by laser were used to fabricate PVSCs. The influence of roughness on absorption of the perovskites layer and extraction properties of the carriers across the interface were discussed. The results showed that the device on the FTO substrate etched by laser with 4A current intensity showed a highest power conversion efficiency, with an enhancement of 13.2% compared with that on the unetched substrate due to the improved scattering of light in the photoactive layer. Our result is expected to open up a new way to enhance the PCE of PVSCs.
