Second-Order Jahn-Teller Distortions and Dynamic Lattice Polarizability as the Origin of Broadband Emission in Bi3+-Doped Cs2SnCl6
Shruti Prasad, Pabitra Kumar Nayak, Dibyajyoti Ghosh
Lead-free vacancy-ordered perovskites (VOHPs) such as Cs2SnCl6 have emerged as promising materials for optoelectronic applications but typically suffer from wide band gaps and low…
Data-driven Discovery of Novel High-performance Quaternary Chalcogenide Photovoltaics
Nikhil Singh, Mohammad Ubaid, Pabitra Kumar Nayak +4
Photovoltaic materials facilitate the conversion of sunlight into electricity by harnessing the interaction between light and matter, offering an eco-friendly and cost-efficient en…
Experimentally observed defect tolerance in the electronic structure of lead bromide perovskites
Gabriel J. Man, Aleksandr Kalinko, Dibya Phuyal +3
Point defect tolerance in materials, which extends operational lifetime, is essential for societal sustainability, and the creation of a framework to design such properties is a gr…
A-site Cation Influence on the Conduction Band of Lead Bromide Perovskites
Gabriel J. Man, Chinnathambi Kamal, Aleksandr Kalinko +7
Hot carrier solar cells hold promise for exceeding the Shockley-Queisser limit. Slow hot carrier cooling is one of the most intriguing properties of lead halide perovskites and dis…
