External magnetic eld effect on bifacial silicon solar cell's electric power andconversion efficiency

Abstract

This article presents a modelling study of external magnetic eld effect on a bifacial silicon solar cell's electricpower and conversion efficiency.After the resolution of the magnetotransport equation and continuity equation of excess minority carriers, wecalculate the photocurrent density and the photovoltage and then we deduce the solar cell's electric power beforediscussing the in uence of the magnetic eld on those electrical parameters.Using the electric power curves versus junction dynamic velocity we determine the maximum electric power, theoperating point of the solar cell, and the conversion efficiency according to magnetic eld intensity. The numerical datashow that the solar cell's maximum electric power and conversion efficiency decrease with magnetic eld intensity.
