High Performance Perovskite Solar Cells through Surface Modification, Mixed Solvent Engineering and Nanobowl-Assisted Light Harvesting

In spite of the phenomenal efficiency progression of the organometal halide perovskite-based solar cells (PSCs) over the past few years, detailed understanding of the working mechanisms and effective measures to overcome the main weaknesses such as the long-term instability are of central importance. This paper provides a brief review of our most recent research on high-performance PSCs including the diethanolamine-modification of NiO surface, the mixed solvent engineering and the mesoporous TiO₂ nanobowl (NB) array assisted light harvesting.
