Thermal curing of perovskite films

Thin-film PV technologies, particularly organo-metal halide perovskite light absorption layer based technology, have emerged as a promising next-generation PV technology due to their high power conversion efficiency, low cost, short energy pay pack time and application veracity. The efficiency of perovskite solar cells has rocketed up from 3.8% in 2009 to a 25.2% record in 2019, showing a great potential becoming a key player on the solar energy market.
The perovskite absorption layer is usually applied in a solvent, which dries and crystallises in a curing process. The performance of the solar cells is strongly affected by the crystal structure and morphology of this layer. Monitoring the perovskite film during the curing is crucial for faster development of processes for high-quality perovskite films with good reproducibility.
