SC04–Impact of surface texture on bifacial silicon heterojunction solar cell carrier loss

Tonita E. M., Valdivia C. E., Hinzer K.

We investigate the impact of surface texturing on current loss as a function of depth and wavelength in high efficiency bifacial silicon heterojunction solar cells operating at their maximum power output. We couple 3D ray tracing with TMM thin-film boundary conditions for optical simulations and solve Poisson’s drift-diffusion equations to calculate carrier recombination under both […]
