Electricity is bound to increase and as a consequence the increased demand on fossile fuels as well as possible regulations on CO2 emissions are bound to increase the wholesale electricity costs. A change of paradigm is now happing.
Solar cells based on chalcogenide films, such as CdTe and CIGS, are at the forefront in thin film solar cell technology in terms of commercial production and laboratory record effiency. However, reliance on the heavy metal Cd and nonabundant elements In presents a barrier toward meeting the multiterawatt scale target for renewable energy supplied by photovoltanics.
Kesterite thin film is an emerging alternative chalcogenide solar cell absorber that provides diversification away from the noe-earth-abundant elements.
In this seminar, I will talk about the R&D trend of thin film solar cells based on Kesterite thin films.
