Laser-Annealing and Solid-Phase Epitaxy of Selenium Thin-Film Solar Cells [PDF]
ACS Appl. Energy Mater. 2023, 6, 17, 8849-8856, 2023 Selenium has resurged as a promising photovoltaic material in solar cell research due to its wide direct bandgap of 1.95 eV, making it a suitable candidate for a top cell in tandem photovoltaic devices. However, the optoelectronic quality of selenium thin-films has been identified as a key bottleneck for realizing high-efficiency selenium solar cells ...

Selenium and the role of defects for photovoltaic applications [PDF]
Phys. Rev. Mater. 8, 015402 (2024), 2023 We present first principles calculations of the electronic properties of trigonal selenium with emphasis on photovoltaic applications. The band gap and optical absorption spectrum of pristine selenium is calculated from many-body perturbation theory yielding excellent agreement with experiments.
