In general, conversion efficiency of such solar cell architecture has a plateau around 18–19% for mono-crystalline Si (c-Si) and 17–18% for multi-crystalline Si (mc-Si) solar cells . In fact, the Al-BSF results in fairly high rear recombination losses and has a high degree of parasitic absorption of light .
Furthermore, Multiple researchers have conducted reviews on diverse cooling technologies that enhance the performance of solar cells. For instance, a review paper by Ghadikolaei provides an overview of various cooling technologies and their impact on the performance of commercially available photovoltaic (PV) cells (Anon (2002)).
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).
The photovoltaic sector is now led by silicon solar cells because of their well-established technology and relatively high efficiency. Currently, industrially made silicon solar modules have an efficiency between 16% and 22% (Anon (2023b)).
1.8W. The process requirements for manufacturing SHJ solar cells have several advantages compared with those for conventional homojunction c-Si solar cells. The first advantage is the low thermal budget during the heterojunction formation; the deposition temperature of a-Si:H and ITO layers is usually less than 250°C.
Solar cells of this kind, characterized by reduced material usage, lower manufacturing costs, and flexibility, typically achieve conversion efficiencies ranging from 6% to 15% (Jaiswal et al., 2022).
