The follow-up fabrication of silicon solar cell can be divided into two types: crystalline silicon wafer composed of monocrystalline polycrystalline silicon wafer and thin film silicon wafer. The further application of solar cells is inseparable from their material and manufacture. Therefore, this paper also discusses the various ways of applications of the diverse types of solar cells.

Solar cells based on expensive single-crystal silicon (Si) wafers account for the majority of devices sold today. Thin-film Si solar cells significantly reduce costs, but their efficiency is the same or lower than average. New technologies currently in the pipeline will be much more efficient but with lower costs to encourage
Today, about 95 percent of solar cells are made using crystalline silicon (c-Si). Most commercial designs employ a c-Si photoactive layer with a thickness of around 160–170 μm. However, since silicon alone makes up nearly half the cost of each solar panel, experts believe that next-generation c-Si solar cells will be much thinner.
