The Solar Cells research group currently focuses on the investigation of novel photovoltaic concepts and the development of advanced multiphysics, multiscale tools for their analysis and design. Specifically, we are studying i) novel photonic management methods for solar cells including light-trapping, guided-mode resonance, and photon recycling; ii) electronic transport in Quantum-Dot based solar cells; iii) novel architectures for multiple junction solar cells. The capabilities in electrical and optical simulation include both the use of commercial tools (Synopsys TCAD Sentaurus; Rsoft (FullWave, DiffractMOD); COMSOL Multiphysics) and of in house developed tools for “quantum-corrected” carrier transport in nanostructured solar cells and coupled electrical-optical simulations of photonically-enhanced solar cells. The research builds on prior investigation in the modeling of dye sensitized solar cells and optoelectronic devices for telecom such as photodiodes and electro-absorption modulators. The group recently led and implemented the Horizon 2020 project Thin Film Quantum Dot solar cells (TFQD, 01/2016-12/2018) for the development of light-trapping enhanced III-V solar cells for space applications. Other topics of research are towards the development of QD infrared photodetectors. Multiple collaborations with other research institutions are ongoing, including Radboud University, Tampere University, and Università degli Studi di Milano-Bicocca.
