After 40 Years of Searching, Scientists Identify The Key Flaw in Solar Panel Efficiency

Science Alert  June 8, 2019
Silicon solar cells containing boron and oxygen are one of the most rapidly growing forms of electricity generation. However, they suffer from significant degradation during the initial stages of use. Using ab initio modeling, an international team of researchers (UK, Portugal, Belarus, Australia) proposes structures of the BsO2 defect which match the experimental findings. They argue that the dominant recombination process associated with degradation is trap-assisted Auger recombination. This assignment is supported by the observation of above bandgap luminescence due to hot carriers resulting from the Auger process…read more. Open Access TECHNICAL ARTICLE
