Abstract
An electrochemical method for producing a hole extraction layer in a solar cell based on organic semiconductor materials. Conjugated polymers are used to build a hole extraction layer and a photoactive layer. Poly(3,4-ethylenedioxythiophene) (PEDOT) is used as a hole extraction layer and is deposited electrochemically from an aqueous solution on an indium tin oxide (ITO) electrode. A nanofibrilar or nanogranular morphology of the PEDOT is achieved by carrying out the polymerization in the presence of a surfactant. A photoactive layer of poly(3-hexylthiophene)/[6,6]-phenyl-C-butyric acid methyl ester (P3HT/PCBM) can be deposited by spin-coating technique on top of the PEDOT layer.
