Problems solved by technology

However, if the amount of electrolyte is less, the distance between the conductive glasses will also be reduced, and the working electrode will easily contact the counter electrode and cause a short circuit. Such a battery will be more difficult to package.

Embodiment 1

[0030] The transparent conductive substrate adopts the FTO (F-doped tin oxide) conductive glass of Japan Nippon Sheet Glass Company. The conductive glass is cleaned in an ultrasonic water bath and then dried.

[0031] Preparation of TiO 2 Nanoparticle Slurry: Preparation of Nano-TiO by Sol-Gel Method 2 slurry. Prepare a certain concentration of triethylamine solution 50mL and 0.1mol / L titanium acetate solution 250mL. Under vigorous stirring, the triethylamine solution was added to the titanium acetate solution; in order to make TiO 2 The particles are uniform to prevent rapid agglomeration of the particles, and the triethylamine solution is slowly added to the titanium acetate solution using a dropping funnel. With the addition of triethylamine solution, white flocs were formed. Constantly stirring, after about 15h, it becomes a stable sol. Then filter to remove large particles of TiO 2 .

Abstract

The invention discloses a method for packaging a dye-sensitized solar cell, which comprises the following steps of: adopting a screen printing technique to print a TiO2 nano-particle sizing material on a piece of FTO conductive glass for manufacturing a working electrode so as to form a plurality of isolated rectangular flaky TiO2 films; sintering the TiO2 films printed in the first step (S1) and soaking the TiO2 films in a dye; doping a certain proportion of spacing agent into a liquid packaging adhesive to serve as a packaging material, and uniformly coating the packaging material in gaps of the TiO2 films; covering a counter electrode on the working electrode and applying a uniform pressure to the counter electrode; and injecting an electrolyte into spaces limited by the packaging material, sealing the spaces, and finishing the solidification of the packaging material. The scheme can improve the performance and the service life of the dye-sensitized solar cell, and is helpful for efficient and large-area production and processing of batteries.

Description

technical field [0001] The invention relates to the field of solar cell production, in particular to a packaging method for dye-sensitized solar cells. Background technique [0002] A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. With the increasing global population in recent years, energy depletion and global pollution have become problems that cannot be ignored. As an inexhaustible renewable energy source, solar energy plays an irreplaceable and important role in the process of human beings seeking new energy sources. More and more countries have begun to implement the "Sunshine Plan" to develop solar energy resources and find new impetus for economic development. [0003] The phenomenon of photoelectric conversion was first observed by French scientist Henri Becqμerel in 1839. It was not until the advent of the first practical semiconductor solar cell in 1954 that the conversio...
