BaCd2P2: a promising impurity-tolerant counterpart of GaAs for photovoltaics
Gideon Kassa, Zhenkun Yuan, Muhammad R. Hasan +5
BaCd2P2 (BCP) has been recently identified as a new solar absorber with promising optoelectronic properties. This work demonstrates that, despite having a low precursor purity (98.…
Low-Temperature Synthesis of Stable CaZnP Zintl Phosphide Thin Films as Candidate Top Absorbers
Shaham Quadir, Zhenkun Yuan, Guillermo Esparza +14
The development of tandem photovoltaics and photoelectrochemical solar cells requires new absorber materials with band gaps in the range of ~1.5-2.3 eV, for use in the top cell pai…
Assessing carrier mobility, dopability, and defect tolerance in the chalcogenide perovskite BaZrS
Zhenkun Yuan, Diana Dahliah, Romain Claes +4
The chalcogenide perovskite BaZrS has attracted much attention as a promising solar absorber for thin-film photovoltaics. Here, we use first-principles calculations to evaluate…
Discovery of the Zintl-phosphide BaCdP as a long carrier lifetime and stable solar absorber
Zhenkun Yuan, Diana Dahliah, Muhammad Rubaiat Hasan +17
Thin-film photovoltaics offers a path to significantly decarbonize our energy production. Unfortunately, current materials commercialized or under development as thin-film solar ce…
Electrochemical Screening of Contact Layers for Metal Halide Perovskites
Moses Kodur, Zachary Dorfman, Ross A. Kerner +6
Optimizing selective contact layers in photovoltaics is necessary to yield high performing stable devices. However, this has been difficult for perovskites due to their complex int…
Dimethylammonium additives alter both vertical and lateral composition in halide perovskite semiconductors
Sarthak Jariwala, Rishi Kumar, Giles E. Eperon +3
Adding a large A-site cation, such as dimethylammonium (DMA), to the perovskite growth solution has been shown to improve performance and long-term operational stability of halide…
