Spiro-Linked Bisphosphonate Self-Assembled Monolayers for Efficient and Stable Perovskite Solar Cells.
Bisphosphonate-anchored self-assembled monolayers (SAMs) play a pivotal function in the development of high-performance inverted perovskite solar cells (PSCs). However, the strong aggregation tendency of SAM molecules on substrates significantly limits the power conversion efficiency (PCE) of the devices. In this study...
