Critical review on the controllable growth and post-annealing on the heterojunction of the kesterite solar cells

JPhys Energy
Kesterite-structured solar cells have drawn significant attention due to their low-cost and environmental friendly composition. Recently, a remarkable certified power conversion efficiency (PCE) of 14.9% has been achieved, indicating a broader prospect ...

Silver‐Alloyed Wide‐Bandgap (Ag,Cu)(In,Ga)S2 Thin‐Film Solar Cells With 15.5% Efficiency

Progress in Photovoltaics: Research and Applications, EarlyView.
This study reports improvements in compositional homogeneity, microstructure, enhanced radiative recombination, and extended carrier lifetime of CIGS absorber via Ag incorporation. The optimal Ag‐alloyed CIGS solar cells achieve 15.5% PCE and 948 mV VOC, competing with the VOC of the Ag‐free reference sample from the same batch.

A Study of Energy Band Gap Temperature Relationships for Cu2ZnSnS4 Thin Films

, 2011
The temperature dependent band gap energy of Cu2ZnSnS4 thin film was studied in the temperature range of 77 to 410 K. Various relevant parameters which explain the temperature variation of the fundamental band gap have been calculated using empirical and
