Pinhole-free hole transport layers significantly improve the stability of MAPbI sub(3)-based perovskite solar cells under operating conditions

Pinhole-free 2,2',7,7'-tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-sp irobiflu orene (spiro-MeOTAD) hole transport layers (HTLs) were deposited on perovskite films. MAPbI sub(3)-based perovskite solar cells employing the pinhole-free HTL showed a prolonged lifetime under one sun and wa...

Zusammenfassung:Pinhole-free 2,2',7,7'-tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-sp irobiflu orene (spiro-MeOTAD) hole transport layers (HTLs) were deposited on perovskite films. MAPbI sub(3)-based perovskite solar cells employing the pinhole-free HTL showed a prolonged lifetime under one sun and was operated at the maximum power point. The solar cell architecture (planar versusmesoporous-layers) was also observed to strongly influence the cell's stability.
