METHOD OF PRODUCING PHOTOVOLTAIC CELLS BASING ON HYBRID NANOCOMPOSITE MATERIAL Russian patent published in 2014 - IPC H01L31/06 B82Y40/00 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of manufacturing photovoltaic cells and can be used in solar panels. The claimed method is based on a step-by-step manufacturing a sensibilising layer on the basis of a nanocomposite hybrid structure, containing mesoporous TiO₂, semiconductor quantum points and an organic dye, and consists in the fact that in order to reduce the thickness of the QP layer, adsorbed on the TiO₂ surface, a technological stage of the preliminary removal of an excess quantity of molecules of a solubiliser of the semiconductor quantum points from the solution and partly from the surface of quantum points, is introduced. It makes it possible to avoid the formation of dendrite structures on the surface of mesoporous TiO₂ and results in the formation of thin layers of the quantum points on the surface of mesoporous TiO₂, providing conditions for highly efficient transfer of the charge.

EFFECT: increased efficiency of energy transformation in a photovoltaic cell.
