- Abstract
- Kesterite materials are a low-cost, eco-friendly alternative for thin-film solar cells but have stalled at ~12% efficiency due to a large open-circuit voltage deficit. This work replaces traditional physical deposition with molecular-ink solution processing, which improves film morphology, phase control, and allows germanium alloying for precise bandgap tuning without harming material quality. By combining temperature-dependent current-voltage measurements with SCAPS simulations, the study updates characterization and modeling approaches to match the enhanced optoelectronic properties of these solution-processed films. Overall, this work encompasses both the development of enhanced kesterite solar cells and their advanced opto-electrical characterization and modeling, very relevant to the next-generation of thin-film photovoltaic technologies.
