<p>The present invention generally comprises a solar cell and a solar cell fabrication process. Photogenerated electrons and electron-holes may have a short lifetime or low mobility that permits the electrons or electron-holes to recombine before reaching the junction. A percolating solar cell device may shorten the distance that the electrons and electron-holes need to travel to reach the junction. The percolating solar cell may be formed by depositing a silicon containing layer with poragens and then decomposing the poragens to create openings such as pores in the silicon containing layer. In one embodiment, the silicon containing layer is deposited and then etched anodically to create openings in the silicon containing layer. The layer deposited over the silicon containing layer may extend into the openings. By extending into the openings, the distance to the junction for electrons and electron-holes may be reduced and more electrons and electron-holes may reach the junction.</p> |
