Our group’s research spans from the investigating novel earth-abundant compounds to demonstrate their applicability in operational devices and also concentrates on solving the major issues in improving their performances by deeply studying their different properties.
Sputtered-based Earth-Abundant Copper Chalcogenides (CZTSSe, and CTS) Thin Film Solar Cells
Thin film solar cells based on CdTe and CIGS are amongst the most promising second generation solar cell technologies. However, availability of tellurium and indium in the earth's crust may limit the terrawatt-scale production of thin film solar cells based on CdTe and CIGS. Our group is working on the development of high efficiency CZTSSe and CTS-based thin film solar cells using scalable sputtering method. This involves the preparation of absorber layers via annealing of sputtered-deposited precursor layers under the S/Se vapor atmosphere.
Recently, our group has achieved ~ 11.8% efficiency for CZTSSe thin film solar cells, which is very close to the record efficiency of 12.7% by IBM group. Based on these achievements, we have established a partnership relationship with many research institutes and schools that are actively involved in research and development both at home and abroad to develop thin film solar cells with record efficiency.
