A method of making a plurality of photovoltaic cells ( 400, 800, 1112 ) for charging a battery ( 1230 ) of an electronic device ( 1010 ) includes forming by a self-assembly process a plurality of interdigitated photovoltaic cells ( 400, 800, 1112 ) between two terminal electrodes ( 102, 202, 132, 232 ) coupled to the battery ( 1230 ). One electrode is a transport conductive material ( 102, 202 ) including a conductive material ( 106, 206 ) having sidewalls ( 110, 210 ) defining a plurality of pores ( 112 ). A conductive electrode material ( 126, 226 ) is formed over an electrolyte ( 124, 224 ) which is formed over a sensitizing material ( 122, 222 ) which is formed over an active transport material ( 114, 214 ) on the sidewalls ( 110, 210 ). |
