Tandem Electrolysers for High‐Efficiency CO2‐to‐Acetate Conversion Driven by Full‐Spectrum Solar Energy

Carbon Energy, EarlyView.
A full‐spectrum solar‐driven tandem electrolysis system enables efficient CO2‐to‐acetate conversion by spectrally splitting sunlight and coupling high‐temperature SOEC CO2‐to‐CO electrolysis with ambient CO reduction. The integrated design achieves a solar‐to‐acetate efficiency of 15.8%, demonstrating effective energy‐quality matching for solar carbon ...

Multiple Synergistic Effects Enabling Efficient Kesterite Solar Cells via Introducing a Cu2O‐Bi2O3 Sacrificial Interlayer

Carbon Energy, EarlyView.
The Cu2O‐Bi2O3 thin film as a sacrificial interlayer at the back contact of kesterite solar cells achieves multiple synergistic optimizations in bulk defects, interface defects, back‐contact band offset, and MoSe2 properties. This enhances carrier separation, suppresses interface recombination, and enables DMSO‐processed kesterite devices to reach a ...
