The conventional solar cell is a solid wafer-like semiconductor structure in which sunlight is absorbed, creating positive and negative electric charge carriers that are swept from the structure by an internal electric field. Lyndsey McMillon-Brown, inBiomimicry for Aerospace, 2022
Nilofar Asim, ... Marzieh Badiei, inNanomaterials for Green Energy, 2018 A solar cell is a device that converts solar energy, a clean and vital renewable energy source, into electricity and can help to overcome the global energy crisis.
The standard solar cell is a thin semiconductor device that is based on silicon material and metal as depicted in Figure 13.1. It is a sandwich of silicon material between two conducting metal electrodes. The front metal electrode is structured such that it allows entrance of light.
First Generation of Photovoltaic Cells Silicon-based PV cells were the first sector of photovoltaics to enter the market, using processing information and raw materials supplied by the industry of microelectronics. Solar cells based on silicon now comprise more than 80% of the world’s installed capacity and have a 90% market share.
Various PV configurations based on the conventional solar-cells have been studied, such as single and double junctions a-Si based PV developed by Han and co-workers [ 154] and GaAs p-n junction PV developed by Turner's group [ 155 ]. Some of the significant PEC/solar-cell tandem configurations are listed in Table 7. Fig. 8.
Other possible solar cell types are organic solar cells, dye sensitized solar cells, perovskite solar cells, quantum dot solar cells etc. The illuminated side of a solar cell generally has a transparent conducting film for allowing light to enter into the active material and to collect the generated charge carriers.
