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…
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…
Quantum-mechanical effects in photoluminescence from thin crystalline gold films
Alan R. Bowman, Álvaro Rodríguez Echarri, Fatemeh Kiani +6
Luminescence constitutes a unique source of insight into hot carrier processes in metals, including those in plasmonic nanostructures used for sensing and energy applications. Howe…
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…
