    摘要： Voltage breakdown devices for solar cells are described. For example, a solar cell includes a semiconductor substrate. A plurality of alternating N-type and P-type semiconductor regions is disposed in or above the substrate. A plurality of conductive contacts is coupled to the plurality of alternating N-type and P-type semiconductor regions. A voltage breakdown device is disposed above the substrate. The voltage breakdown device includes one of the plurality of conductive contacts in electrical contact with one of the N-type semiconductor regions and with one of the P-type semiconductor regions of the plurality of alternating N-type and P-type semiconductor regions disposed in or above the substrate.

    摘要： 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.
