Investigation of Various Commercial PEDOT:PSS (Poly(3,4-Ethylenedioxythiophene)Polystyrene Sulfonate) As A Hole Transport Layer in Lead Iodide Based Inverted Planar Perovskite Solar Cells

Inverted-type perovskite solar cells have drawn remarkable attention due to solution-processable, straightforward configuration, low-cost processing, and manufacturing at very high throughput, even on top of flexible materials. The hole transport material (HTM) plays a vital role to achieve high performance in inverted type of perovskite solar cells. Herein, we report on the effect of different commercial PEDOT:PSS such as PH 1000, PH 500, P VP AI, and P T2, on the performance of CH3NH3PbI3-based planar perovskite solar cells.
