There are two causes of charge carrier motion and separation in a solar cell: 1. drift of carriers, driven by the electric field, with electrons being pushed one way and holes the other way2. diffusion of carriers from zones of higher carrier concentration to zones of lower carrier concentration (following a gradient of chemical potential).

Abstract. Generally, a thin (>50 nm) transition metal oxide (TMO) film (such as TiO 2) is employed as an interfacial layer (also called a blocking layer, BL) between FTO and mesoporous TiO 2 in a dye-sensitized solar cell (DSC). The function of this layer is to provide full coverage of FTO so as to reduce back electron recombination without …

How a Solar Cell Works
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron …
