Implication

Experimental study demonstrates 14.8% active area efficiency in ZnO/CdS/CuInSe2 thin-film cells, highlighting how optimized coevaporation improves grain orientation and reduces recombination.

Key Points

Develop high-efficiency single-junction thin-film solar cells by optimizing CuInSe2 layer synthesis and heterojunction properties.
Fabricated n-ZnO/n-CdS/p-CuInSe2 cell structures on soda-lime glass substrates.
Applied controlled deposition rate and substrate temperature profiles during the coevaporation process to produce the CuInSe2 absorber layer.
Achieved an active area conversion efficiency of 14.8%, representing the highest reported efficiency for a single-junction thin-film solar cell.
Produced large-grained absorber films with strong <112> orientation and low porosity, resulting in reduced recombination rates alongside higher open circuit voltage and fill factor.
