The external quantum efficiencies of three bifacial silicon solar cell structures were measured at various incident light angles. The resulting short circuit current densities and bifacialities of an a-Si/c-Si heterojunction cell were compared over front and rear faces to determine their relative performance and incidence angle modifier for energy yield calculations. The heterojunction cell had the highest bifaciality of the cells considered.
