The silicon thin film solar cell device comprises in successive order from the front side transparent substrate 1: a front side transparent conductive (TCO) layer 2, a multi junction thin-film solar conversion layer 4 comprising amorphous and microcrystalline silicon or their alloys, a back side TCO layer 6, a diffuse reflective layer with one or more contact apertures 8, and a metal contact layer 9 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 diffuse reflective layer increases the light converted into electrical energy in the solar conversion layer and may be deposited by ink-jet printing a solution comprising white pigments such as titanium dioxide. |
