"PEDOT:PSS/silicon heterojunction organic-inorganic solar cells... polished wafers were first diced into 8-mm square pieces and coated with PEDOT:PSS aqueous solution and silver electrodes, in a variety of sequences... improved production speed at lower cost and with a power generation efficiency above 10%," says the author...  large-scale diffusion of photovoltaic power generation. This system could see wider utility in various settings, such as in education or in developing economies"
