Khrypunov G. The physical and technological bases of the optimization thin film solar cells on cadmium sulfide and cadmium telluride base

The object is thin film solar cells on cadmium sulfide and cadmium telluride base. The aim is the development of physical and technological bases of the optimization of thin film solar cells on cadmium sulfide and cadmium telluride base, which are aimed at the advancement of their efficiency, longevity and manufacturability and also at the creation of new types of such instrumental structures, which are adapted to the industrial manufacturing and wide application in overland and transatmospheric conditions. The methods are the magnetron dispersion, thermal vacuum vaporization, X-ray diffractometry, electron microscopy, secondary ion mass-spectroscopy, dual-channel optical spectroscopy, dark-field volt-farad characteristics, bright-field and dark-field volt-ampere characteristics. The results: it is established that the evolution of initial crystalline and power structure of frontal electrodes is capable to limit the efficiency factor of instrumental structures. The new type of thin film solar cells oncadmium sulfide and cadmium telluride base, which has double-sided photosensitivity and is able to be used in tandem photoelectrical converters is created. Application of the achievements to production: Isumskiy state instrument-making factory, Ukrainian optical company "Eurooptics", Technological institute of The National space agency of Ukraine. Field of application: solid state physics, physics of semiconductors, solar power engineering
