THEORETICAL AND EXPERIMENTAL STUDY OF SOLAR CELL TEMPERATURE CONDITION IN SPACEPV 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 threedimensional 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.
