In ten years, halide perovskite (PVSK) solar cells reached efficiency comparable to silicon photovoltaic (PV) on small area devices (active area less than 1 cm2). This promising new PV technology can further be considered for industrial exploitation and economical transition if the performance gap between laboratory cells and module devices will be nullify by overcoming the main scaling up issues: the module design, the interconnection patterning and the material/process engineering optimization. Materials processes, nucleation and crystal growth optimization play a substantial role to switch from non-scalable/glove box environment to scalable/ ambient air environment conditions. Here, a full semi-automatic scalable process based on meniscus coating techniques and assisted by green anti-solvent air quenching is demonstrated to fabricate efficient and stable PVSK solar modules in ambient conditions. The developed coating procedure permits the fabrication of several highly reproducible small area cells with an efficiency exceeding 17%. Corresponding reproducible modules with a 93% geometrical fill factor and optimized patterning process achieved a champion efficiency more than 16% on mini- and sub-modules. The reported method can pave the way for a scalable, mass production, and stable out of the glovebox PVSK module fabrication on large scale. Dye-Sensitized Solar Cells (DSSCs) appear very attractive for building-integrated photovoltaics (BIPV) application, because of unique features like tunable color and good transparency. The dreamed low-cost fabrication is realistic only if reliable and scalable processes by pilot line and/or plant factory) are designed, developed and optimized for large-area, efficient and stable devices. We demonstrated the reproducible fabrication of DSSC solar panel by screen-printing techniques. The module champion efficiency was 5.1% with 35.7% transparency (AVT- Average Visible Transmittance), and ISOS-D-2 and ISOS-L-1stability.
Luigi Vesce is Senior Researcher and Lecturer of Nanoelectronics at CHOSE (Centre for Hybrid and Organic Solar Energy), Department of Electronic Engineering, University of Rome Tor Vergata, where he received a PhD in Telecommunications Engineering and Microelectronics in 2011. In the last few years, he developed a pilot-line for a public/private consortium (Dyepower) to produce 10000 m2/year of dye-sensitized solar cell (DSSC) panel for BIPVs (Building Integrated PhotoVoltaics). He collaborates with research institutes and startup/spin-off companies on third generation PV devices and process engineering, and on quality control optimization. His research activity deals with the discovery, development, and fabrication by coating/printing techniques, and scaling- up of efficient and stable dye sensitized and perovskite solar technologies for outdoor and indoor applications. He is involved in national and international PV-related projects, author of several contributions for international journals and conferences and committee member/chairman of conferences about renewable energies.
