When Are Capacitance–Voltage, Drive‐Level Capacitance Profiling, and Fast‐CV Actually Insensitive to Interface and Bulk Defects?

Solar RRL, Volume 10, Issue 6, 29 March 2026.
Capacitance‐based techniques are widely applied to profile doping in one‐sided semiconductor junctions, yet defect states can distort interpretation. Time‐dependent simulations compare capacitance–voltage, drive‐level capacitance profiling, and Fast‐CV, revealing their sensitivity to trap dynamics and providing guidance for interpreting capacitance ...

Overview of Ge-incorporated kesterite solar cells [PDF]

Chinese Science Bulletin, 2020
Kesterite (CZTS(e)) solar cell has attracted tremendous interest for its feature: Earth-abundant composition, convenient fabrication process, environmental friendliness and low cost. However, the severe large voltage deficient in CZTS(e) solar cell remains a challenge for further enhancement of the power conversion efficiency (PCE).

Li Incorporation Induces Surface Chemical Disorder in Solution‐Processed Cu2ZnSn(S,Se)4

Advanced Materials Interfaces, Volume 13, Issue 5, 4 March 2026.
Lithium incorporation into Cu2ZnSn(S,Se)4 (CZTSSe) thin‐film semiconductors is highly beneficial for solar power conversion efficiencies, although directly visualising its impact on the absorber is difficult. Energy‐filtered photoemission electron microscopy measurements reveal lithium alloying induces surface chemical disorder of CZTSSe, highlighted ...
