Efficient Perovskite Hybrid Solar Cells by Highly Electrical Conductive PEDOT:PSS Hole Transport Layer

PEDOT:PSS doped with PEO (poly­ethylene oxide) is demonstrated to be an efficient hole extraction layer due to its high electrical conductivity and extremely smooth surface. This material is able to boost the efficiency of planar heterojunction perovskite hybrid solar cells.
