“…Densely populated areas (in particular commercial buildings) are the core contributors to building energy consumption and emissions [2]. The tailored implementation of Building Integrated PhotoVoltaic (BIPV) solutions has the potential to highly increase the overall building energy efficiency [3][4][5] while improving the quality of life under multiple aspects [6,7], especially if a more rational use of energy is implemented [8][9][10]. Considering the wide-range of BIPV technologies, their tailored implementation has the potential to improve the quality of human life under multiple prospects [6,7].…”

The increasing trend towards decarbonization requires the reduction of the environmental impact of the building sector that currently accounts for approximately 40% of the total CO2 emissions of European countries. Even though Luminescent Solar Concentrator (LSC) panels could be a very promising technology to be installed in urban environments, there is still little implementation of LSC panels in building façades. Here, the realization of a Ventilated Façade (VF) integrating an LSC device as an external pane is presented and a preliminary numerical and experimental investigation is used to evaluate the interaction between the different structure components. Thanks to the realization of a dedicated mock-up finite element method, models are calibrated and validated against experimental measurements, showing a good correspondence between simulated and measured data. Moreover, the electrical characterization of the LSC panel confirms that large area devices can be used as an external skin of VF, reporting a photovoltaic efficiency of 0.5%. The system’s thermal and optical properties (estimated thanks to the software COMSOL Multiphysics) encourage the continuation of the research by considering different technologies for the VF internal skin, by scaling up the case study, and by running the simulation of an entire building considering winter and summer energy demands.

“…A possible solution to further decrease the cost of BIPV technologies is the manufacture of devices that have static or monoaxial concentrating components in the so-called buildingintegrated concentrating photovoltaic (BICPV) technology. Data from [27][28][29][30] estimated that systems with a low-concentration factor specifically designed for building integration can reduce the cost of the device by up to 40% with respect to similar non-concentrating devices. According to the most general definition, a solar concentrator is an object redirecting light rays from a larger area, namely the aperture area, to a smaller one, called the receiver of the absorber area [31].…”

Building-integrated photovoltaic technologies have considerable potential for the generation of onsite renewable energy. Despite this, their market penetration is in a relatively embryonic phase with respect to grounded or building-attached solutions, and they have limited commercial application. Their integration into building façades may represent a key asset in meeting the net-zero emissions by 2050 scenario, in particular for high-rise buildings in which the roof-to-façade ratio is unfavorable for the fulfillment of the energy load using only roof photovoltaic technology. Moreover, different façade orientations extend the production time throughout the day, flattening the power generation curve. Because of the present interest in BIPV systems, several researchers have conducted high-quality reviews focused on specific designs. In this work, various photovoltaic technologies and methods used to manufacture façade BIPV devices are reviewed with the aim of presenting researchers with the recent technological advancements and providing an overview of photovoltaic systems designed for different purposes and their applications rather than a detailed analysis of a specific technology. Lastly, future prospects and the limitations of building-integrated photovoltaic devices are presented.
