Closed-Form Solutions and Parameterization of the Problem of Current-Voltage Performance of Polycrystalline Photovoltaic Modules Deployed at Fixed Latitude Tilt

Research output: Contribution to conferencePaper

Abstract

One obstacle to wider market penetration for thin-film polycrystalline photovoltaic (PV) modules is the lack of field performance data, notably temperature-coefficient data for the current-voltage (I-V) characteristics over all irradiance levels encountered in the field. Generally, temperature coefficient and performance data are available only in a restricted range of illumination around 1-sunintensity. In this paper, the I-V performance data are presented, analyzed, and parameterized across a wide range of illumination levels and temperatures, allowing the modeling of the performance for three polycrystalline PV technologies: cadmium telluride, copper indium diselenide, and polycrystalline silicon. The data are scrutinized for clear-sky and diffuse-illumination conditions.
