| Outline of Final Research Achievements |
In order to fabricate next-generation CZTSSe thin film solar cells which consist of earth-abundant elements (Cu, Zn, Sn, S and/or Se), the preparation conditions of the sequential evaporation method using compounds were examined. The S content in the CZTSSe thin film was controlled by changing the amount of sulfur evaporation in the second step. CZTSSe and CZTSe thin film solar cell were fabricated and demonstrated the efficiency of 1.55% and 3.93%, respectively. These values were updated our previous performance. Moreover, the open circuit voltage was improved by adding the thermal treatment after the sequential evaporation.
