Highly efficient and stable inverted perovskite solar cell employing PEDOT:GO composite layer as a hole transport layer

Abstract The beneficial use of a hole transport layer (HTL) as a substitution for poly(3,4-ethlyenedioxythiophene): polystyrene sulfonate (PEDOT:PSS) is regarded as one of the most important approaches for improving the stability and efficiency of inverted perovskite solar cells. Here, we demonstrat...
