The organic-inorganic composite perovskite with a 3-dimensional structure has a strong absorption coefficient due to a suitable bandgap (1.55 ev), high open-circuit voltage (Voc) due to low exciton binding energy, and band gap control according to composition and structure control. And the solution process internal high-efficiency thin film solar cells are easy to develop, which has attracted much attention. In spite of the successful development of perovskite solar cells (PSCs), there are urgent needs for development of efficient PSCs. For example, balanced charge‐carrier transport is a precondition for high‐efficient PSCs. So we have stabled HTL and/or ETL optimization. In this work, we will introduce the recent progress to improve the efficiency of 3-dimensional organic-inorganic compound PSCs, based on our results.
