The HCLs with a pore structure can offer a large interface to enhance hole collection; however, the series resistances are also increased by the relatively pore morphology. Photovoltaic device with the largest short circuit current (Jsc) and efficiency is achieved using poly(3,4-prppylenedioxythiophene) (PProDoT) as HCLs due to its highly porous structure and reasonable series resistance. By further optimizing the thickness of the HCLs in the solar cell, a power efficiency of 3.57% under simulated sun light is achieved. © 2008 American Chemical Society.[SDGs]SDG7Fullerenes; Photovoltaic cells; Pore structure; Solar cells; Solar equipment; Controlled growths; ELectrochemical methods; Hole collectors; Photovoltaic devices; Pore morphologies; Porous structures; Power efficiencies; Series resistances; Sun lights; Solar energyjournal article10.1021/jp804221u
