High efficiency methylammonium lead triiodide perovskite solar cells: the relevance of non-stoichiometric precursors

Methylammonium lead iodide perovskite solar cells with improved performance and stability have been successfully prepared by using a non-stoichiometric PbI2 : CH3NH3I ratio in the precursor solution, and yield a power conversion efficiency (PCE) of above 19% under 1 sun for the champion cell.
