Optical Simulation of Light Management in CIGS Thin-Film Solar Cells Using Finite Element Method

In this paper we present an optical simulation of light management in Cu(In,Ga)Se2 thin-film solar cells with reduced absorber layer thickness, with the goal of absorption enhancement in the absorber layer. The light management was achieved by texturing of the substrate layer, and the conformal growth of all the following layers was assumed. Two texturing shapes have been explored: triangular a...

Optical Design of Textured Thin-Film CIGS Solar Cells with Nearly-Invisible Nanowire Assisted Front Contacts

The conductivity of transparent front contacts can be improved by patterned metallic nanowires, albeit at the cost of optical loss. The associated optical penalty can be strongly reduced by texturization of the cell stack. Remarkably, the nanowires themselves are not textured and not covered in our design. This was shown by optical modeling where the width of the nanowire, the texture height an...

Thin-film Silicon Solar Cells

The simplest semiconductor junction that is used in solar cells for separating photogenerated charge carriers is the p-n junction, an interface between the p-type region and ntype region of one semiconductor. Therefore, the basic semiconductor property of a material, the possibility to vary its conductivity by doping, has to be demonstrated first before the material can be considered as a suita...
