PEDOT or poly(3,4-ethylenedioxythiophene) is a conductive polymer that is widely used as a hole transport material in applications like photovoltaics, displays, biosensors and LEDs. In photovoltaics, PEDOT is used as a hole transport and buffer layer in organic and perovskite solar cells. It facilitates the extraction of holes from the active layer and transport them to the electrode. PEDOT...
