Organic and perovskite semiconductors for energy technologies. ERC Grantee (StG2016, CoG2021); Wallenberg Academy Fellow 2017; SSF Future Research Leader 2020; Tage Erlander Prize 2020; Wallenberg Scholar 2024.

Prof. Gao’s group dedicates its efforts to energy devices, with the ambition to both improve device performance and understand the underlying fundamentals. Their current investigations include organic semiconductors and metal halide perovskites, with research focuses such as: Fullerene-free organic solar cells, including low voltage losses, green solvent processing and new applications. Perovskite solar cells, with a focus on understanding and improving the stability Perovskite LEDs, with the motivation to improve the device performance and also explore new applications Lead-free perovskites, aiming to tune the optoelectronic properties and explore their magnetic properties Perovskites for other applications, e.g. X-ray detection and lasers
