PCBM additive strategy lifts efficiency and durability of inverted perovskite solar cells
Researchers at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences have engineered an optimized electron transport layer for inverted perovskite solar cells that raises both power conversion efficiency and operational stability. The work, led by Prof. Pan Xu at the Institute of Solid State Physics, focuses on controlling the behavior of the fullerene derivative PCBM at th
