The efficiency of silicon (Si)-based solar cells has nearly reached its maximum capacity at approximately 25%. Conversely, III-V compound semiconductor-based solar cells have consistently exhibited enhancements in performance, increasing by approximately 1% annually. These solar cells recently accomplished a remarkable efficiency of 47.1%.
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%.
Silicon solar cells have a limited ability to capture low-energy photons, which limits their efficiency, especially in low-light conditions. Moreover, the practical limits in obtaining maximum efficiency are restricted by many factors including different types of recombinations and losses (Shah et al., 2004).
The typical loss of incident light from reflection from a silicon solar cell's front surface is 30%, which lowers the efficiency of the device's total power conversion (Wang et al., 2017). The reflection loss can be expressed as Equation 13. 5.2.2. Parasitic absorption
Moreover, thick silicon solar cells suffer from unavoidable losses in power conversion efficiency due to non-radiative recombination of photo-generated charge carriers during their relatively long path to electrical contacts at the extremities of the cell.
Due to their high energy efficiency, silicon wafers have a 90% market share in solar cells, but the price to build these panels is higher than the alternatives (Smith et al., 2014). In c-si cells, thick wafers are used, which increases material costs.
