Abstract
Through the H2020 BE-SMART project, we work on the validation and industrialization of new materials (and processes) for manufacturing next-generation cost-efficient, reliable and highly aesthetic/performing BIPV. On this basis, we aim at introducing novel multifunctional and transformative BIPV elements, in the concept/form of Energy Positive Glazing (EPoG). The project's developments so far indicate the high potential of e.g. using colored encapsulants, interferential filter technique and/or ceramic-based colored glazing for implementing novel “transformative” BIPV with high aesthetic quality. Yet, since BIPV's primary function is electricity production, we need to understand and quantify the impact of such coloration solutions on the performance (and reliability, in longer terms) of future BIPV. In this paper, we present an experimental comparative study on the optical and electrical performance of multiple color coated and patterned BIPV glazing solutions, towards their upscaling and commercialization. In particular, we performed optical transmission measurements and light intensity-/angle-depent IV characterization on 25 different colored glass samples and 10 different colored/patterned glass PV laminates respectively. The measurement results and their discussion presented in this paper provide valuable insights into the optical-electrical performance of the investigated colored BIPV glazing, as well as a first identification of BIPV industry-relevant colors and patterns with the best potential “compromise” between aesthetics and performance, for future energy positive glazing applications.

Summary
À rationale and aim of the studyBIPV industry has intensified R&D efforts, the last few years, towards the technical maturity and commercialization of several off-the-shelf products for façade and roof integration. With a closer look at the BIPV market and R&D landscape, we identify certain barriers and setbacks of diverse origins, throughout the whole BIPV value chain, that eventually have been holding back the To address such challenges, a shift in mindset from PV to the building industry is an essential first step. A shift in mindset from PV to the building industry is an essential first step With this in mind, through the EU-funded project BE-SMART we aim to introduce novel multifunctional and transformative BIPV, in the concept/form of Energy Positive Glazing (EPoG) [3]. Through the EU-funded project BE-SMART we aim to introduce novel multifunctional and transformative BIPV, in the concept/form of Energy Positive Glazing (EPoG) [3] The latter shall replace (or transform) traditional passive building materials (e.g. tiles, aluminum façade or standard architectural glass) by innovative active elements. A central R&D activity in BE-SMART is to validate and industrialize new materials
