Embodiment 1

[0014] A random copolymer sealing film of polyethylene and polymethacrylic acid with a thickness of 100 microns is selected, laid flat on a metal plate, and a sealing film of a certain shape is prepared by laser scribing technology. Then it is accurately positioned between the photoanode and the counter electrode, heated to 100°C under a flat press, heated and sealed for 20 minutes, and then taken out to form a sealed battery case. The dye photosensitizer and electrolyte are injected into the sealed battery box through the small hole on the battery box, and then the small hole on the battery box is sealed by heat sealing with a polymer sealing film and a thin glass sheet.

Abstract

This invention relates to a sealing method for a dye sensitization nm film solar cell which takes polymer film or adhesive as the sealing material to seal the cell box and the hole and seal the electrolyte solution between the anode and cathode to finished the process of a dye sensitization nm film solar cell, solving the key problem of seal to realize large scale cell process.

Description

technical field [0001] The invention relates to a battery sealing method, in particular to a dye-sensitized nano film solar battery sealing method. Background technique [0002] In 1991, the laboratory of Professor M.Gr tzel of the Swiss Institute of Technology in Lausanne reported a new dye-sensitized nano-thin film solar cell on nature (O'Regan, B.; Gr tzel.M, 1991, 353, 737). The results immediately received widespread international attention and attention. Since 1991, it has been an international research hotspot. [0003] Dye-sensitized nano-thin-film solar cells use organic photosensitive functional molecules combined with semi-semiconductor nanomaterials to photoelectrically convert solar energy. It combines the functions and characteristics of organic and inorganic photoelectric materials: using organic photosensitive dyes to efficiently collect light The advantages of fast charge transfer and separation of semiconductor materials, combined with the porosity and hi...
