Abstract

Obtaining good quality perovskite absorber film remains a challenging task that limits performance of planar perovskite solar cells. . In this work, we demonstrated the importance of pre-heating treatment on perovskite nucleation and phase transition. . Fine-tuning the appropriate pre-heating and st...
