Summary / Abstract: The 32% EU-wide binding target for renewables by 2030 [1] testifies the will to satisfy the growing need for energy by using renewable sources, and the market projections for the Building Integrated PhotoVoltaic (BIPV) sectors indicates these kind of technology as one of the most promising to reach this goal. Indeed, BIPV market is expected to grow at a CAGR (Compound Annual Grow Rate) of more than 14.79% during the forecast period of 2020 – 2025. In particular, among all PhotoVoltaic (PV) technologies Luminescent Solar Concentrator (LSC) panels represent a promising way to widen the BIPV sector. Indeed, they can serve different purposes with respect to mere power generation and contrary to standard PV modules they can be easily integrated in transparent or semi-transparent building façades. According to Lehmann & Peter report the building façades in the Europe have a potential area of 2411 Km2 equal to 3 m2 /cap in densely populated regions [2] . However, the application of LSC panels on an industrial scale is still immature, in fact there is no evidence of commercially available PV panels based on LSC technology. The main drawback is their uncompetitive price-to-watt ratio whit respect to the one of commercial BIPV devices, which range from 1.2 €/Wp, for glass-glass PV panels designed for architectural integration, to 8 €/Wp for PV glass based on a-Si technology [3]. The performances of standard PV technologies are highly affected by shading and, if bypass devices are not installed, the PV modules can suffer of permanent damage in case of partial illumination [4]. Thanks to the absorption and re-emission mechanism for which they can convert both direct and diffuse radiation, LSC panels are instead extremely tolerant to shading [5]. Therefore, they are perfect candidates for BIPV application, especially in the countries with a high population density or in which diffuse solar radiation is dominant [6]. Moreover, thanks to their optical propertiesthey have the potential to be exploited in greenhouse roof panels, to produce electricity while increasing agricultural productivity [7].
