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 ...

Investigating synthesis of Cu2ZnSn(Se1-x,Sx)4 for values of 0≤x≤1 by S for Se substitution and direct sulphidisation of metallic precursors [PDF]
Thin layers of Cu2ZnSn(Se1-x,Sx)4 were produced by selenisation and subsequent sulphur substitution of DC sputter-deposited metallic CZT precursors on soda-lime glass. Values of x=(0, 0.07, 0.12, 0.17, 0.28, 1) were measured by EDS.

Decoupling of optoelectronic properties from morphological changes in sodium treated kesterite thin film solar cells [PDF]
Sodium is typically used during the synthesis of kesterite thin films to enhance the performance of solar cells. As sodium tends to affect grain growth and morphology, it is difficult to analyse solely the electronic effects of sodium as dopant.

Overview of Ge-incorporated kesterite solar cells [PDF]
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
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 ...
