Please cite this article as doi: 10.1002/ep.13370 A state of the art review of PV-Trombe wall system: Design and applications Omer Khalil Ahmed * Khalaf Ibrahim Hamada ** Abdulrazzaq M. Salih ** Raid W. Daoud * * Northern technical University ** Tikrit University Abstract 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 paper, 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 paper is beneficial to engineers and researchers and can provide information for future studies.
