Competition Between Controllable Non-Radiative and Intrinsic Radiative Second-Order Recombination in Halide Perovskites
Dengyang Guo, Alan R. Bowman, Sebastian Gorgon +13
Halide perovskite solar cells have demonstrated a rapid increase in power conversion efficiencies. Understanding and mitigating remaining carrier losses in halide perovskites is no…
Distinguishing Inner and Outer-Sphere Hot Electron Transfer in Au/p-GaN Photocathodes
Fatemeh Kiani, Alan R. Bowman, Milad Sabzehparvar +2
Exploring nonequilibrium hot carriers from plasmonic metal nanostructures is a dynamic field in optoelectronics, driving photochemical reactions such as solar fuel generation. The…
Spatially resolved photoluminescence analysis of Se passivation and defect formation in CdSeTe thin films
Alan R Bowman, Jacob J Leaver, Kyle Frohna +3
CdTe is the most commercially successful thin-film photovoltaic technology to date. The recent development of Se-alloyed CdSeTe layers in CdTe solar cells has led to…
Relaxed current matching requirements in highly luminescent perovskite tandem solar cells and their fundamental efficiency limits
Alan R. Bowman, Felix Lang, Yu-Hsien Chiang +8
Here we use time-resolved and steady-state optical spectroscopy on state-of-the-art low- and high-bandgap perovskite films for tandems to quantify intrinsic recombination rates and…
