Coatings Free Full Text Facile Solution Spin Coating

The hole blocking layer plays an important role in suppressing recombination of holes and electrons between the perovskite layer and fluorine doped tin oxide (FTO). Morphological defects, such as cracks, at the compact TiO2 hole blocking layer due to rough FTO surface seriously affect performance of perovskite solar cells (PSCs). Herein, we employ a simple spin coating SnO2 thin film solution

Facile preparation of high quality perovskites for

First published on 24th April 2017. High performance perovskite solar cells are strongly dependent on the quality of the perovskite layer. Here, a high crystallinity, sufficiently smooth and pinhole free CH 3 NH 3 PbI 3 film with excellent photovoltaic properties has been successfully prepared by a facile and reproducible approach, in which the CH 3 NH 3 I (MAI) was deposited directly onto wet
