To summarize, silicon semiconductors are currently playing a critical role in the large-scale manufacturing of solar cells with good efficiency and durability. In the future, all-perovskite tandems are expected to become more prevalent as they are cheaper to produce compared to silicon cells.
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).
