Solar cell component and its module

Abstract

The invention provides a solar cell component, comprising a first tubular structure, an electron transporting layer which is coated on the first tubular structure, a second tubular structure, a metallic layer coated on the second tubular structure, a dye layer coated on the electron transporting layer, electrolyte filled in a gap, wherein, the first tubular structure and the second tubular structure are different in tube diameter; the electron transporting layer and the metallic layer are arranged correspondingly, and the gap formed between the two tubular structures. The invention also provides a solar cell module comprising a plurality of solar cell components.

Description

Solar cell components and their modules technical field The present invention relates to a solar cell assembly, in particular to a tubular solar cell assembly and its module. Background technique At present, in the development of solar cell technology, it is developing in the direction of (1) cost reduction, such as the development of thin-film solar cell technology, and (2) the direction of improving photoelectric conversion efficiency, such as the development of multi-junction solar cell technology. In thin-film solar cell technology, dye-sensitized solar cell (dye-sensitized solar cell, DSSC) (also known as Graetzel Cell) has the powerful advantages of low raw material cost and relatively simple manufacturing process, which attracts many research institutions or companies to invest in technology and products. develop. At present, the energy conversion efficiency of dye-sensitized solar cells can reach up to 11%. The conversion efficiency of dye-sensitized solar cell...

AI Technical Summary

Problems solved by technology

Because the dense titanium dioxide layer 16 on the electrode makes the adsorption area of ​​the dye monolayer 18 small, the amount of absorbed solar energy is very little, and the photoelectric conversion efficiency is not high (less than 1%)
