Management of energy consumption for building's air conditioning is a vital issue for resource saving and environmental protection. The use of solar energy to generate electricity by solar cells is essential nowadays. However, the disadvantage of solar panels is the elevated temperature in work, especially in the hot sunny climate that leads to efficiency decline. Also, there is a problem with heating during the night and cloudy days. For the last 20 years, there has been a rapid development in the field of integrated solar technologies. A hybrid PV/Trombe wall (PV/ TW) system suggested being an efficient and durable conversion system of solar energy. The design of the PV/TW system considered one of the focusing areas of the present research to make it more economically feasible. The idea of building the photovoltaic-Trombe wall has appeared as one of the green technologies. Several published works at that time are included for integrating PV/TW system. This chapter devoted to reviewing the theoretical and practical studies conducted on this system for developing and improving electrical and thermal performance.

“…The results showed that double glazing filled with argon PV‐TW gave the maximum photovoltaic efficiency at a roof pitch angle of 20° and an air gap thickness of 0.2 m. Ventilated PV‐TW and PV cell installed through the roof also reduced the cooling load of the room up to 50%. The optimum thickness of the PV‐TW was recommended to be 0.3–0.4 m for thermal heating under the decrement factor about zero and thermal load leveling of 0.01 . The influence of the air channel thickness on the ventilation and heat transfer rates was investigated computationally in the built‐in PV‐Trombe wall channel .…”

Global energy demand for the future can be met using renewable energy resources, and one of its harvesting tools is the photovoltaic (PV) technology. The combination of solar cell technology and Trombe wall is one of the most important research topics at present. PV-Trombe walls are receiving great attention because of their applications for simultaneous electricity generation and heating. In this article, a review of available literature covers different designs of a PV-Trombe wall system besides its thermal and electrical applications. The review covers in detail the influence of design and operational parameters including the glass cover, use of direct current fan, facade width, air vent, air gap thickness, thermal insulation, packing factor, coverage, heat storage, air mass flow rate, PV cell cooling, southern windows, and tilt angle of solar cell on the performance of PV-Trombe walls. Furthermore, comparison between the PV-Trombe wall system and classical Trombe wall as well as the applicability of this novel system are revealed. This review article is beneficial to engineers and researchers and can provide information for future studies.

“…They found maximum of 2:0 kW h useful thermal energy gain for SPVT roof which reflects its higher heat removal characteristics. Taffesse et al (2016) reported the periodic analysis of SPVT thermal-trombe wall (SPVT-TW) in order to analyze the thermal heating of a single room for winter conditions for the New Delhi (India) climatic conditions. For thermal heating as per requirement, they conclude that the optimum thickness of the wall should be in the range of 0:3-0:4 m for thermal load leveling of 0:01 with nearly zero decrement factor.…”
