Within (crystalline silicon) solar cell modeling, a skin means the thin region from the quasi-neutral bulk to the actual surface or metal contact, including e.g. doping profiles, induced band-bending or top-cells of a tandem configuration. A typical highly doped skin is commonly characterized by its main lumped properties: effective …

Solar Cell Efficiency
This chapter is based on concepts from Solid-State Physics and from Quantum Theory. Unfortunately it is not possible to explain, in a precise manner, the functioning of a solar cell without using these concepts. We have therefore thought it …
The concept of a bifacial solar cell absorbing sunlight from the front and rear sides has first been published in a patent by H. Mori in 1960 . At that time, the idea was to use pn-junctions at the front and rear sides in order to improve the collection of photogenerated charge carriers at both wafer surfaces. Bifacial solar cells with ...
