Solar-energy conversion by combined photovoltaic converters with CdTe and CuInSe2 base layers

Development of Back and Front Contacts for CdTe Layer in Tandem Flexible Photoelectric Converters on Basis of CdTe/CuInSe2

“…Polyimide/ITO/CdS/CdTe/-Cu/ITO SCs with different thicknesses of the CdTe base layer were investigated. As shown in [12], the maximum efficiency of the SC is observed when the cadmium telluride layer is d CdTe = 2 5 μm. In [24,25], it was also found that at a given thickness of the cadmium telluride layer, optimization of the photoelectric conversion is observed at a well-defined thickness of the cadmium chloride layer and the time of the "chloride" treatment.…”

“…At present, laboratory samples of tandem photoelectric converters based on CdTe/CIS have been tested only when formed on glass substrates [12]. At the same time, the problem of electrical connection of two solar cells to the instrumental tandem structure has not been solved.…”

Investigating an alternative electricity supply system for preventing emergencies under conditions of limited capacity

“…It is shown that such solar cells have not yet reached their theoretical maximum but they demonstrate high values of degradation stability [5]. The authors of works [5,6] suggest the production of solar cells based on CdS/CdTe using the electrochemical method. However, the application of this method also did not make it possible to improve the effectiveness of such instrument structures.…”
