Photo-generation profiles in deeply-etched, two-dimensional patterns in interdigitated back contact solar cells

Interdigitated back contact (IBC) crystalline silicon solar cell model has been developed by using SILVACO in order to achieve design optimization in non-conventional device configurations. The SILVACO software was employed to evaluate performance of IBC solar cell as a function of texture while kee...
