Abstract
The basic drawback of single junction solar cells is their inability to absorb multiple wavelengths of light. Tandem solar cells are designed to extract maximum energy from the light by absorbing multiple wavelengths. A multilayer solar cell was fabricated using multiple coating techniques. The characterization of the cell was carried out to analyze its properties and behavior under different conditions. The effect of layers’ thickness on the light absorption efficiency is discussed in this paper. The thickness of P-type material is varied to examine the effect of layer thickness on the band gap..
