Application

Organic hole transport layer (HTL) play very important role for realizing high performance and low-cost planar p-i-n perovskite solar cells (pero-SCs).Our 4,4′,4′′,4′′′-germanetetrayltetrakis(N,N-bis(4-methoxyphenyl)aniline), also known as Ge-OMe TPA can substantially simplify synthetic procedure by reducing device cost. This HTL can also facilitate the sequent growth of high-quality perovskite films, giving a significantly enhanced photovoltaic efficiency.
