Substrate-preheating Effects on PbI2 Spin Coating for Perovskite Solar Cells via Sequential Deposition
The preheating of mesoporous TiO2 electrodes just before PbI2 deposition has quite an important effect on the sequential deposition of CH3NH3PbI3 perovskite layer for the utilization of solar cells. The effects were disclosed by comparisons of the surface morphologies and the photovoltaics with and without preheating.
