Research from the MSE and Chemistry departments at UCF has been featured on the cover of physica status solidi (a). This work was carried out by Geoffrey Gregory (Graduate Student, MSE), Corbin Feit (Graduate Student, MSE), Zhengning Gao (Postdoctoral Researcher, MSE), Prof. Parag Banerjee (Associate Professor, MSE and REACT Cluster), Prof. Titel Jurca (Assistant Professor, Chemistry and REACT Cluster), and Prof. Kristopher O. Davis (Assistant Professor, MSE and RISES Cluster). The team showed that by precisely inserting hydrogen in a few monolayer aluminum oxide passivation layer during atomic layer deposition (ALD), charge carrier recombination lifetimes of over one millisecond can be achieved. Coupling this layer with an ALD hole‐selective molybdenum oxide film results in a low resistivity, fully transparent, passivating hole contact. This film stack helps pave the way for more efficient and cost-effective solar energy technologies by reducing optical and recombination losses in these devices, with other potential applications for photodetectors, displays, and transparent electronics.
