| 摘要 |
This invention relates to a method for producing thin film solar cells with a back-side reflective layer, wherein the solar module is a silicon thin film device placed in-between a back side planar substrate and a front side planar glass superstrate placed in parallel and a distance from the back side planar substrate, wherein the silicon thin film device comprises in successive order from the front side: a front side transparent conductive (TCO) layer, a multi junction thin-film solar conversion layer comprising amorphous and microcrystalline silicon or alloys thereof, a back side TCO-layer, a diffuse reflective layer with one or more local through-going apertures, and a metal layer covering the reflective layer and which is in contact with the back side TCO-layer through the one or more apertures in the reflective layer. The invention also relates to a method for forming the solar cell.
