Single crystal modules are usually smaller in size per watt than their polycrystalline counterparts . Why is silicon used in solar cells? The atomic structure of silicon makes it one of the ideal elements for this kind of solar cell.
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%.
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 .
The crystalline silicon cell needs about 1.1 eV (Electron Volts) of energy to release an electron in the semiconductor; any energy that is more or less than this simply goes through the cell with no effect . This energy used to release the electron is unique for each material and is known as the material’s band gap.
The first generation of the solar cells, also called the crystalline silicon generation, reported by the International Renewable Energy Agency or IRENA has reached market maturity years ago . It consists of single-crystalline, also called mono, as well as multicrystalline, also called poly, silicon solar cells.
Photovoltaic (PV) conversion of solar energy starts to give an appreciable contribution to power generation in many countries, with more than 90% of the global PV market relying on solar cells based on crystalline silicon (c-Si). The current efficiency record of c-Si solar cells is 26.7%, against an intrinsic limit of ~29%.

Crystalline silicon or (c-Si) is the crystalline forms of silicon, either polycrystalline silicon (poly-Si, consisting of small crystals), or monocrystalline silicon (mono-Si, a continuous crystal). Crystalline silicon is the dominant semiconducting material used in photovoltaic technology for the production of solar cells. These cells are assembled into solar panels as part of a photovoltaic system to generate solar power
