| Outline of Final Research Achievements |
Aiming at improving the performance of next-generation chalcogenide thin-film solar cells, which have the advantages of low resource constraints and low cost of raw materials, the film fabrication technology was investigated. I have developed 3S method, which is a new film-fabricating technology to produce CZTSSe thin-film solar cells by sulfurizing the precursor deposited with CZTSe compound. In the 3S method, the open-circuit voltage of CZTSSe thin-film solar cells could be improved to 720 mV by performing high-temperature sulfurization and addition of alkali metals. For CTS thin-film solar cells, I achieved the world's highest open-circuit voltage of 302 mV by high-temperature sulfurization of a precursor containing silver and alkali metals.
