Ultrafast reconfigurable topological-modulators-based photonic processing accelerator
Abstract The rise of artificial intelligence has triggered exponential growth in data volume, demanding rapid and efficient processing. High-speed, energy-efficient, and parallel-scalable computing hardware is thus increasingly critical. We demonstrate a wafer-scale non-volatile photonic computing chip using topological modulators.

TOPCon-based bottom cells for perovskite/silicon tandem solar cells
Keywords perovskite/silicon 2T tandem solar cells Si bottom cells TOPCon SHJ bi-poly TOPCon Introduction Electricity and heat generation account for approximately one-fourth of global greenhouse gas emissions, primarily driven by CO2 emissions from fossil fuel consumption.1 As we seek to decarbonize the electricity mix to mitigate climate change, renewable energy sources such as solar, wind, geothermal, and hydroelectric power are becoming increasingly critical.
Additive-assisted perovskite crystallization on industrial TOPCon silicon for tandem solar cells with improved efficiency
|
Abstract Thin silicon wafers used in tunnel oxide passivated contact tandem solar cells have reduced thermal mass and higher thermal conductivity, which accelerate heat transfer during perovskite subcell deposition. This rapid heat transfer induces fast crystallization of the perovskite layer, compromising film quality and tandem performance. Here we introduce 2-mercaptobenzothiazole, which exhibits dual-mode binding with perovskite organic cations, to modulate crystallization dynamics.

Bifacial tunnel oxide passivating contacts for silicon and perovskite/silicon tandem solar cells with improved efficiency
Abstract The power conversion efficiency (PCE) of conventional tunnel oxide passivating contact (TOPCon) solar cells is fundamentally constrained by front-side recombination losses in both contact and non-contact regions. Here we demonstrate full-size bifacial TOPCon solar cells incorporating patterned front n-type TOPCon fingers and a full-area rear p-type TOPCon emitter, achieving a certified PCE of 26.34%.
