During the past few decades, crystalline silicon solar cells are mainly applied on the utilization of solar energy in large scale, which are mainly classified into three types, i.e., mono-crystalline silicon, multi-crystalline silicon and thin film, respectively .
Crystalline silicon solar cells are the most widely used solar cells, which have intrinsic limitation on the theoretical conversion efficiency (33.7% based on Shockley and Queisser's analysis) , and the actual conversion efficiency of crystalline silicon solar cells is as low as 20%.
The silicon used to make mono-crystalline solar cells (also called single crystal cells) is cut from one large crystal. This means that the internal structure is highly ordered and it is easy for electrons to move through it. The silicon crystals are produced by slowly drawing a rod upwards out of a pool of molten silicon.
Single crystalline silicon is usually grown as a large cylindrical ingot producing circular or semi-square solar cells. The semi-square cell started out circular but has had the edges cut off so that a number of cells can be more efficiently packed into a rectangular module.
Working Principle: The solar cell working principle involves converting light energy into electrical energy by separating light-induced charge carriers within a semiconductor. Role of Semiconductors: Semiconductors like silicon are crucial because their properties can be modified to create free electrons or holes that carry electric current.
Polycrystalline solar cells use liquid silicon as raw material. Since the polycrystalline silicon involves solidification process the materials contain various crystalline sizes. Hence, the efficiency of this type of cell is less than Mono crystalline solar cell. Efficiency of this type of solar cell is 13-15 %.
