Simulated performance of SHJ solar cell was improved from 0.098 to 22.58% for LiF x work functions. Wide bandgap with low work function-based materials are widely used as an electron transport layer to achieve high efficiency in silicon heterojunction (SHJ) solar cells.
What are solar absorbers used for?
These absorbers are promising for applications like solar cells and electromagnetic cloaking because they need unit cell size in the nanometer range, which is feasible using nanofabrication techniques (Hossain et al., 2023). The efficiency of solar cells made of perfect metamaterials can be increased by amplifying the solar waves that hit the PMA.
How efficient are silicon solar cells in the photovoltaic sector?
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)).
Are silicon solar cells efficient in low-light conditions?
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).
Are silicon wafers better than c-Si solar panels?
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.
