Using only 3–20 μm -thick silicon, resulting in low bulk-recombination loss, our silicon solar cells are projected to achieve up to 31% conversion efficiency, using realistic values of surface recombination, Auger recombination and overall carrier lifetime.
The theoretical limiting efficiency of the crystalline silicon solar cell under non-concentrating sunlight is about 29% . This is not far below the theoretical limit for any single junction solar cell.
According to these approaches (usually referred to as semi-empirical), the efficiency of a solar cell depends on the optical bandgap (E gap) of the semiconductor material indicating that, for crystalline Si (E gap ∼1.1 eV), the maximum efficiency stays in the ∼ 15–22 % range.
The reasons for silicon’s popularity within the PV market are that silicon is available and abundant, and thus relatively cheap. Silicon-based solar cells can either be monocrystalline or multicrystalline, depending on the presence of one or multiple grains in the microstructure.
Photovoltaics provides a very clean, reliable and limitless means for meeting the ever-increasing global energy demand. Silicon solar cells have been the dominant driving force in photovoltaic technology for the past several decades due to the relative abundance and environmentally friendly nature of silicon.
Additionally, it evaluates efficiency improvement techniques such as light management and spectral utilization. While the efficiency of Si-based solar cells has plateaued around 25%, the efficiency of III–V compound semiconductor-based multi-junction solar cells is increasing.
