Probing concentrator solar cell performance at high flux with localized irradiation

    Abstract

    The macroscopic parameters that characterize photovoltaic (PV) performance, including their spatial dependence, especially at high flux, are determined with extensive localized solar measurements on high-efficiency concentrator solar cells. We present two studies that explore (a) the impact of nonuniform flux distribution on PV behavior, (b) how PV parameters vary across the cell surface (of particular interest in many high-concentration optical systems) and (c) the sensitivity of PV parameters to the spatial variation of series resistance Rs that stems from irregular cell metallization. In so doing, we identify current-voltage trends unique to strongly inhomogeneous illumination and to Rs losses at high flux.
