Flexible organo-metal halide perovskite solar cells on a Ti metal substrate†
Abstract
Organo-metal halide perovskite solar cells have received much attention in the field of photovoltaics in recent years. Herein, we report a flexible perovskite solar cell based on a metal substrate. It showed a power conversion efficiency of over 6% for the first time using a silver thin film as a semi-transparent top electrode on a Ti substrate.
