My group’s current research is centered on understanding the fundamental processes involved in converting solar energy. We focus on studying photophysical phenomena in various types of solar cells, including excitonic solar cells with polymers, small organic molecules, hybrids, and perovskites. Key processes like exciton dissociation, charge carrier generation, transport, recombination, and triplet state formation are explored using techniques such as broadband transient absorption (TA) pump-probe spectroscopy, time-resolved photoluminescence (TRPL) spectroscopy, and other steady-state and transient experiments. Additionally, our team explores the device physics of solar cells by using a variety of time and frequency domain experimental techniques such as transient photocurrent or voltage (TPC/TPV), Impedance spectroscopy (IS), and Intensity modulated photocurrent spectroscopy (IMPS). We have a keen interest in the characterization of thin film morphology and microstructure using different microscopy and scattering methods to elucidate the structure -property relationship. We strive to enhance existing spectroscopic methods and develop new measurement tools to gain unprecedented insights into photophysical phenomena.
