In summary, for a real silicon solar cell, there is a trade-off between parasitic absorption, resulting from photonic support structures made of a material other than the crystalline silicon absorber layer, and surface recombination, resulting from texturing the crystalline silicon and thereby increasing surface area. Both these detrimental effects should be carefully

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
The classification, density, distribution of dislocations, and their interactions with other defects in Si can affect the lifetime of minority carriers and thereby reduce the performance of Si solar cells. In order to achieve higher cell efficiency, crystals with less or even no dislocation should be obtained.
Efficiency losses in the solar cell result from parasitic absorption, in which absorbed light does not help produce charge carriers. Addressing and reducing parasitic absorption is necessary to increase the overall efficiency and performance of solar cells (Werner et al., 2016a).
Throughout the years, the evolution of solar cells has marked numerous significant milestones, reflecting an unwavering commitment to enhancing efficiency and affordability. It began in the early days with the introduction of crystalline silicon cells and progressed to thin-film technology.
Dislocation is a common extended defect in crystalline silicon solar cells, which affects the recombination characteristics of solar cells by forming deep-level defect states in the silicon bandgap, thereby reducing the lifetime of minority carrier.
The technology of dismantling and processing crystalline-silicon solar cells is still very immature. The physical method is to roughly separate the solar cells. If the fine components are not processed, it will still cause a waste of resources and will not fully realize the secondary utilization of resources.
