Modified Back Contact Interface of CZTSe Thin Film Solar Cells: Elimination of Double Layer Distribution in Absorber Layer

Advanced Science, 2018
Double layer distribution exists in Cu2SnZnSe4 (CZTSe) thin films prepared by selenizing the metallic precursors, which will degrade the back contact of Mo substrate to absorber layer and thus suppressing the performance of solar cell.

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 ...

Effect of the Order-Disorder Transition on the Seebeck Coefficient of Nanostructured Thermoelectric Cu₂ZnSnS₄

Nanomaterials, 2019
Bulk samples of kesterite (Cu2ZnSnS4, CZTS) were produced by cold-pressing and sintering of CZTS powders obtained via reactive ball-milling. An increase in the Seebeck coefficient of more than 100 μV/K, almost doubling the expected value, is noticed
