Solar cells are a critical component to the transition to renewable energy sources, and enhanced power conversion efficiency (PCE), or amount of power captured with a given amount of sunlight, increases the practicality of solar power in a society with high energy demands.
Perovskite solar cells that use all-inorganic perovskite light-absorbing materials are more thermally stable than organic-inorganic hybrid counterparts, but suffer from lower PCE. Researchers have overcome this hurdle in all-inorganic perovskite solar cells (PSC) by adding a conductive fullerene-derivative interlayer to enhance PCE and thermal stability.
