The PVsquared² research group – led by Prof. Giulia Grancini – is a highly multidisciplinary team composed of chemists, physicists, and engineers dedicated to the development of Perovskite Solar Cells for next-generation photovoltaics. The group’s focus spans from fundamental physics to advanced material design and fabrication, in a collective effort to deliver high-efficiency, long-stability, and environmentally sustainable photovoltaic devices. The main research activities are:

• Investigate the photophysical properties of perovskite films using advanced spectroscopic techniques and computational models, to gain a deeper understanding of charge dynamics and material behavior.
• Explore innovative material solutions – lead-free perovskites, low-dimensional structures, hybrid interfaces – to develop efficient perovskite solar cells that are custom-tailored to their intended application, such as IoT powering via indoor photovoltaics.
• Implement green chemistry principles to the establish sustainable recycling protocols and to improve the existing manufacturing processes, mitigating the toxicity and environmental concerns around the scale-up and end-of-life management of perovskite-based technologies.

Operating at the cutting edge of frontier research, the PVsquared² group represents a leading example of Italian scientific excellence in solar energy research, with a strong impact on the energy transition, and with a clear vision for the future perspectives of the transformative technology that are Perovskite Solar Cells.
