Abstract

The effects of spectral albedo on bifacial silicon heterojunction photovoltaic cell performance is explored in six locations in North America using an optoelectronic drift-diffusion model. We model seven spectral albedos using the scaled rear irradiance method and compare to broadband values. Cell performance varies geographically, with the maximum efficiency of 22.6% calculated for Cambridge Bay (69°N) with snow ground cover, and maximum output power of 216 W/m2 for Mexico City (20°N) with white sand. Neglecting spectral effects of albedo can under or over-estimate power by >2%, which can significantly impact system-level energy yield.
