The application of camphorsulfonic acid doped polyaniline films prepared on TCO-free glass for counter electrode of bifacial dye-sensitized solar cells

摘要: Abstract In this paper, we assembled a low-cost and bifacial dye-sensitized solar cell with an optically transparent TCO (transparent conducting oxide)-free counter electrode using camphorsulfonic acid-doped polyaniline coated on normal glass. This polymer was fabricated by spin coating TCO-free glass substrate followed optimizing process of film thickness thermal treatment. Because the acid doped had high conductivity superior electrocatalytic activity, it could successfully act as that performs dual role, transporting electrons from to external circuit reducing redox couple in electrolyte. The photovoltaic performances film, 84% front illumination 93% rear conventional Pt glass, exhibited. complementary absorption properties dye electrochromic PANI/CSA advantage light side illumination, particularly used effective for cell.
