Some info re Paragraf partnership and Solar efficiency level - https://www.paragraf.com/partnerships/
Solar cell efficiency improvement – Verditek
Traditional solar cells have effectively reached their maximum level of efficiency, at around 23-24%. Improvements of <0.5% are considered highly significant. Performance is constrained by the metal mesh used to disperse current across the cell, and protect it from damage. The shading effect of the mesh prevents around 3% of the surface area from absorbing light.
Depositing optically transparent, highly conductive graphene directly onto the solar cell surface facilitates current dispersal and eliminates shading. In principle, this will improve solar cell efficiency by 3%. Paragraf is working in partnership with Verditek, which is supplying solar cells for graphene deposition. A project to prove the principle has been completed, and a further Joint Development Partnership has now been agreed to advance the technology for the first large-scale graphene silicon solar cell.
