Effect of Different Photovoltaic Materials on Energetic and Exergetic Performance of Photovoltaic Thermal Arrays

Abstract

Abstract. The study presents the effect of packing factor of Photovoltaic (PV) module on the room temperature, cell temperature and efficiency of a proposed Building Integrated Semi-transparent Photovoltaic Thermal (BiSPVT) and Building Integrated Opaque Photovoltaic Thermal (BiOPVT) systems with duct mounted on the roof of the building. Different PV materials like mono-crystalline silicon (m-Si), amorphous silicon (a-Si), poly-crystalline silicon (p-Si), cadmium telluride (CdTe), copper indium selenide (CIS) and hetero-junction with intrinsic thin layer (HIT) have been considered in the analysis under the cold climatic condition of India. Since Srinagar (India) has the cold climatic condition, therefore, its climatic data has been considered in the present analysis.

Energy efficient double-pass photovoltaic/thermal air systems using a computational fluid dynamics multi-objective optimisation framework

“…The design characteristics of the PV cells are [41][42][43][44][45]. In this study, poly-Si is used with a 0.83 packing factor value, 12.35 reference efficiency and 0.0041 K −1 temperature coefficient of power (𝛽 ref ) [8,46,47]. The type of material also affects the optical properties of the PV module, such as thermal emissivity (𝜀 ).…”

“…where 𝐼 𝑚 and 𝑉 𝑚 are the voltage and current at the maximum power point, respectively, 𝐹𝐹 is the Fill factor, 𝐼 𝑠𝑐 is the short circuit current, 𝑉 𝑜𝑐 is the open-circuit voltage [60], 𝐴 𝑠 is the total (aperture) surface area, 𝑉 𝑃𝑉 is the total volume of PV cells and the packing factor is PF = 0.83 (Poly-crystalline) [8,46,47]. 𝜏 𝑛 is the transmissivity of the glass which changes based on the type and number of glass covers.…”
