HIGHLIGHTS
- who: Ha Kyung Park from the Published in partnership with Nanjing Tech University have published the research work: Flexible kesterite thin-film solar cells under stress, in the Journal: (JOURNAL)
- what: This study investigated the implications of Na on the electrical characteristics of flexible CZTSSe photovoltaic devices under mechanical stress. The decrease in VOC may be the main reason for the degradation in the performance of the photovoltaic device.
- how: The results showed that the height of the electron barrier decreased under mechanical stress the carrier separation at GBs weakened which can result . . .
