Scalable High-transparency Perovskite for Integrated Energy-building Photovoltaics

Project description

Transparent perovskite windows for energy-generating buildings

Modern buildings are increasingly expected to generate their own clean energy without compromising design, comfort or natural daylight. Semi-transparent photovoltaic technologies, such as perovskite-based glazing, can be used to transform windows into energy-producing elements without changing visual transparency and colour neutrality. With the support of the Marie Curie Actions programme, the SHINE project aims at developing windows based on perovskites with high concentration of chlorine and able to let visible light and absorb UV energy. Its goal is to advance the use of power-generating glazing with high visible light transmittance.

Objective

Buildings need glazing that generates electricity without compromising daylight or colour neutrality. Metal-halide perovskites—thanks to tunable band gaps and excellent optoelectronic properties—are strong candidates for power-generating windows with high visible transmittance (AVT ≥ 80%). In particular, chloride-rich perovskites (Eg ≈ 3.0 eV) can harvest UV while transmitting visible light, yet current devices remain small-area (~1% PCE) and hard to scale. SHINE tackles the key bottlenecks—crystallisation control and interfacial charge transfer—by (i) establishing blade/slot-die processes that deliver highly uniform Cl-perovskite films with AVT ≥ 80% on 10×10 cm2 substrates, (ii) engineering deep-HOMO, low-absorption hole-transport layers with targeted passivation to minimise voltage losses, and (iii) demonstrating series-connected 100 cm² semi-transparent modules with PCE ≥ 2.2%, Voc ≥ 1.85 V, AVT ≥ 80%, and ISOS-L2 durability. Mechanistic insight will be obtained through in-depth characterization, including XRD for crystallographic analysis; SEM and AFM for surface and morphological mapping; PLQY and TRPL for probing recombination dynamics; and KPFM together with UPS for energy-level and work-function mapping—complemented by FTIR and ssNMR to elucidate chloride-related defect chemistry. Leveraging the host’s upscaling capability and the fellow’s expertise in Cl-based wide-bandgap perovskites, the project will deliver validated modules, open recipes/datasets/scripts, and clear exploitation routes for BIPV. In parallel, the fellow will gain advanced technical training, leadership and project-management experience, and exposure to the host’s extensive European industrial and academic network—substantially enriching their career trajectory and positioning them as a future leader in the field of renewable energy.
