Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
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 current efficiency record of c-Si solar cells is 26.7%, against an intrinsic limit of ~29%. Current research and production trends aim at increasing the efficiency, and reducing the cost, of industrial modules.
In fact, all aspects are in place for approaching 29% except for the existence of a suitable passivated contact technology. Conferences > Conference Record of the Thir... The so-called "limit efficiency" of a silicon solar operating at one-sun is well established at approximately 29%, and laboratory cells have reached 25%.
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.
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.
