Single-Photon Avalanche Diode Image Sensors for Harsh Radiation Environments
The space industry has experienced substantial growth in recent years, leading to rapid advancements in space exploration and space-based technologies. Consequently, the study of electronics and sensor performance in extreme environments has become crucial ...
EPFL2024Chemical Trend of Nonradiative Recombination in Cu(In,Ga)Se2 Alloys
Nonradiative recombination in Cu(In,Ga)Se2 (CIGS) solar cells has long been attributed to the antisite defects MCu (M = In, Ga), but the underlying mechanism is still elusive. Using rigorous first-principles calculations, we demonstrate that the antisites ...
AMER PHYSICAL SOC2023Perovskite Solar Cells with Carbon-Based Electrodes - Quantification of Losses and Strategies to Overcome Them
Ulf Anders Hagfeldt, Bowen Yang, Jiajia Suo, Dmitry Bogachuk
Carbon-based electrodes represent a promising approach to improve stability and up-scalability of perovskite photovoltaics. The temperature at which these contacts are processed defines the absorber grain size of the perovskite solar cell: in cells with lo ...
WILEY-V C H VERLAG GMBH2022Fabrication of Single-Crystalline InSb-on-Insulator by Rapid Melt Growth
Anna Fontcuberta i Morral, Nicholas Paul Morgan, Heera Menon
InSb has the smallest bandgap and highest electron mobility among III-V semiconductors and is widely used for photodetectors and high-frequency electronic applications. Integration of InSb directly on Si would drastically reduce the fabrication cost and en ...
2021Perovskitoid-Templated Formation of a 1D@3D Perovskite Structure toward Highly Efficient and Stable Perovskite Solar Cells
Ulf Anders Hagfeldt, Dongqin Bi, Haibing Xie
Longevity is a long-standing concern for organic-inorganic hybrid perovskite solar cells (PSCs). Recently, the use of low dimensional perovskite has been proven to be a promising strategy to improve the stability of PSCs. Herein, it is demonstrated that 1D ...
