A Bibliographical View on Research and Developments of Photovoltaic and Thermal Technologies as a Combined System: PV/T System

摘要

In this hybrid photovoltaic thermal (PV/T) system, air or water is utilized as a circulating fluid which helps in maintaining electrical efficiency as well as utilization of thermal energy (space heating, crop drying, etc.) at the output. In this article, a review of innovative work in the field of PV/T system and thermal modelling of PV/T collector is presented. The thermal model having different equations for PV-integrated flat plate collector, energy balance for air or water heating system stored thermal energy, the instantaneous energy efficiency and the instantaneous exergy efficiency has been presented. Analytical articulations for different thermal parameters and electrical parameters, considering energy balance for several segments or components of PV/T collector is obtained. Various optimization techniques used in the field of PV/T collector, in view of the exergy concept is also presented.
