20%-efficient polycrystalline Cd(Se,Te) thin-film solar cells with compositional gradient near the front junction

Nature Communications, 2022
Bandgap gradient is a promising approach to improve the open-circuit voltage in thin film solar cells. Here, authors incorporate a Cd(O,S,Se,Te) region to realize the bandgap gradient at front interface and demonstrate Cd(Se,Te) solar cells with reduced ...

Large Transverse Thermoelectric Effect in Weyl Semimetal TaIrTe4 Engineered for Photodetection

Advanced Functional Materials, EarlyView.
This experimental work shows that the anomalous scanning photocurrent response patterns of the Weyl semimetal TaIrTe4${\rm TaIrTe}_4$ under visible and long‐wave infrared illumination are due to a large transverse thermoelectric response of the material.

Self‐Adaptive Anhydrous Passivation Mitigates Open‐Circuit Voltage Loss in Pb‐Sn Mixed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
In this report, a self‐adaptive anhydrous passivation strategy is introduced by incorporating trimellitic anhydride (TMAH) into the perovskite precursor. In situ hydrolysis of TMAH yields trimellitic acid (TMA); ‐C═O/‐COO− groups of TMAH/TMA form a chelate with undercoordinated Pb2+/Sn2+, regulate nucleation, promote (100) orientation, passivate ...
