THEORETICAL AND EXPERIMENTAL STUDY OF SOLAR CELL TEMPERATURE CONDITION IN SPACE PV MODULE WITH LINEAR FRESNEL LENSES

摘要

The results of theoretical and experimental study of solar cell temperature condition in a linear lens concentrator PV module are presented. The theoretical approach was based on a set of a heat-balance equations for heat-spreading plane as well as for a lens panel and accounted for the radiation heat transfer between module elements and with environments. For numerical solution of the thermal conductivity equation describing the three-dimensional field of a heat sink the finite difference method was used. Experimental study of the PV module temperature condition has been carried out on a specially designed test bench on the basis of a vacuum chamber with an inner nitrogen cryogenic screen and a steady-state solar simulator.
