ABSTRACT:
Disclosed is an optical thin film for a thin-film solar cell, which is formed directly on a top surface of the thin-film solar cell having a transparent conductive film layer to provide a high infrared emissivity and a lower solar absorptivity to the thin-film solar cell. The optical thin film is formed through a vacuum vapor deposition process. The thin film makes it possible to provide enhanced infrared emissivity based on its reduced thickness, while suppressing unnecessary incoming solar radiation in a simplified structure to achieve a reduced solar absorptivity so as to maintain desired cell efficiency. The optical thin film of the present invention is capable of achieving reduction in weight of a solar cell, and suitable for use, particularly, in space environments.
