Introduction to Solar Cells
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].

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 …
