Conception and study of a galvanized tubes hybrid PV / T collector for building application

Abstract

During operation of a photovoltaic module, a heat is generated, which systematically increase the temperature of the photovoltaic cell with respect to the ambient temperature and this will cause a drop in performance. Several research projects aimed at developing solutions to limit the rise in temperature of photovoltaic modules, is born beyond the concept of hybrid photovoltaic thermal collectors / (PV / T), which is to superimpose both electrical and thermal energy functions. In this hybrid collector, the fluid flowing in the thermal part to be heated also cools the photovoltaic cells and thereby increases their electric yield. These absorber tubes can have different shapes: round, square and rectangular tubes. In this paper a new configuration of absorber is studied. A thermal and electrical model is performed and tested
