“…A possible alternative for increasing fluid PVT outlet temperature without decreasing PV electrical efficiency, may consist in the use of a heat pump, which uses part of the PV electricity to increase PVT outlet temperature [1,2,9]. Although the basic idea of the PVT was developed about 40 years ago, this product is still far from mature commercialization [10]. Thus, several researchers are investigating several novel PVT arrangements [10][11][12][13].…”

This paper presents a design procedure and a simulation model of a novel concentrating PVT collector. The layout of the PVT system under investigation was derived from a prototype recently presented in literature and commercially available. The prototype consisted in a parabolic trough concentrator and a linear triangular receiver. In that prototype, the bottom surfaces of the receiver are equipped with mono-crystalline silicon cells whereas the top surface is covered by an absorbing surface. The aperture area of the parabola was covered by a glass in order to improve the thermal efficiency of the system. In the modified version of the collector considered in this paper, two changes are implemented: the cover glass was eliminated and the mono-crystalline silicon cells were replaced by triple-junction cells. In order to analyze PVT performance, a detailed mathematical model was implemented. This model is based on zero-dimensional energy balances. The simulation model calculates the temperatures of the main components of the system and the main energy flows Results showed that the performance of the system is excellent even when the fluid temperature is very high (>100 °C). Conversely, both electrical and thermal efficiencies dramatically decrease when the incident beam radiation decreases.

“…Additionally, the adverse effect of crosswinds could be eliminated as the absorber surface is isolated from the ambient by the glazing cover. e. Ventilated PV facades Photovoltaic (PV) cells/modules are nowadays widely used in buildings for the electricity generating capacity from solar radiation [29]. A building integrated photovoltaic/thermal (BIPVT) system which combines building envelopes and photovoltaic (PV) modules, can not only generate electricity in situ, but also reduce the heating load in winter and cooling load in summer for a building's air-conditioning system There are mainly two application methods to construct a DSF based BIPVT system, one is suitable for new buildings, which uses PV modules to replace the external façade of a DSF system in the external envelope directly to constitute a BIPVT system; while the other is suitable for energy-saving reconstruction work for existing buildings, in which the PV modules are added on existing external walls or glass curtain walls to form a BIPVT system.…”

“…When the operating temperature rises, the efficiency falls. Every 1 K increase in operating temperature results in a 0.25% efficiency decline for the amorphous silicon PV cells [29] and around 0.4-0.5% for the crystalline silicon PV cells [30]. Thus it is essential to remove the accumulated heat from the PV cell for the purpose of increasing the electrical efficiency.…”

“…It improved flexibility and lower manufacturing cost than silicon based PV cell. Besides, thickness of CIGS thin film solar cell can be as thin as a few nanometers and very light weight [25]. Based on previous literates, the CIGS based PV/T system is still not comprehensively studied, therefore present study will use the thin film-CIGS type of solar cell combined with flat plate solar collector.…”

Abstract. This paper deals with the efficiency improvement of Copper Indium Gallium Selenide (CIGS) Photovoltaic (PV) and also solar thermal collector. Photovoltaic thermal (PV/T) can improve overall efficiency for PV and also solve the problem of limited roof space at urban area. Objective of this study is to clarify the effect of mass flow rate on the efficiency of the PV/T system. A CIGS solar cell is used with rated output power 65 W and 1.18 m 2 of area. 4 set of experiments were carried out, which were: thermal collector with 0.12 kg/s flow rate, PV/T with 0.12 kg/s flow rate, PV/T with 0.09 kg/s flow rate and PV. It was found that PV/T with 0.12 kg/s flow rate had the highest electrical efficiency, 2.92 %. PV/T with 0.09 kg/s flow rate had the lowest electrical efficiency, 2.68 %. It also had 2 % higher overall efficiency. The efficiency gained is low due to several factors. The rated output power of the PV is low for the area of 1.18 m 2 . The packing factor of the PV also need to be considered as it may not be operated at the optimal packing factor. Furthermore, aluminium sheet of the PV may affect the PV temperature due to high thermal conductivity. Further study on more values of mass flow rate and also other parameters that affect the efficiency of the PV/T is necessary.
