Multiscale Modeling and Back Contact Design of Bifacial Silicon Heterojunction Solar Cells

A back contact of bifacial silicon heterojunction solar cells was investigated and sensitivity of design studied by means of optical and electrical simulations. With 3-D optical simulations the realistic bifacial silicon heterojunction solar cell with metal fingers at the front and back was simulated. Specular illumination was applied at the front and Lambertian diffuse illumination at the back si...
