Embodiment 1

[0030] (1) Preparation of semiconductor electrodes

[0031] Semiconductor nanocrystalline thin film and fluorine-doped tin dioxide conductive glass at a concentration of 3×10 - Soak in 4 mol / liter N3 dye aqueous solution for 24 hours to form a dye layer in the semiconductor nanocrystalline film to obtain a semiconductor electrode.

[0032] (2) Preparation of counter electrode

[0033] The conductive glass coated with fluorine-doped tin dioxide film (FTO conductive glass with a square resistance of 15 ohms manufactured by Qinhuangdao Yaohua Glass Co., Ltd., with a thickness of 4 mm) was cut into small pieces of 5 cm × 2.5 cm. Clean the conductive glass with water first, and then put in H2 with a concentration of 10% by weight. 2 SO 4 activated in. Put the activated conductive glass into the electrolytic tank for electroplating. The electroplating temperature is controlled at 80°C, the current density is controlled at 0.036 A / cm2, and the electroplating time is 2 minutes. A ...

Embodiment 2

[0039] The 100 dye-sensitized solar cell boxes obtained in the above-mentioned Example 1 were subjected to appearance inspection to determine the yield rate of the product, and the results are shown in Table 1.

[0040] Product Yield Calculation

[0041] Product yield (%) = number of qualified products / number of all products

[0042] The qualified product is a product without broken conductive glass.

Abstract

The invention provides a sealed method of a dye-sensitized solar cell (DSSC), comprising the following steps of: coating encapsulant materials on a semiconductor electrode and / or the periphery of a counter electrode and then pressurizing, leveling and solidifying the semiconductor electrode and the counter electrode after film synthesis to form a box body with a cavity in the middle. In coating the encapsulant materials on the semiconductor electrode or / and the periphery of the counter electrode, part(s) of the semiconductor electrode and / or the periphery of the counter electrode is not coated with the encapsulant materials and the partial positions of the semiconductor electrode and the periphery of the counter electrode coated with no encapsulant materials are corresponding to each other, forming an injection hole. The sealed method provided by the invention leaves out the drilling step on conductive glass in the prior art, does not require a thin glass sheet to seal and cover a pore and dramatically improves the quality rate of products at the same time of lowering operation difficulties and enhancing appearance effect.

Description

technical field [0001] The invention relates to a battery sealing method, more specifically, to a dye-sensitized solar battery sealing method. Background technique [0002] Dye-sensitized solar cell refers to a semiconductor photoelectrochemical cell that uses dye-sensitized porous nanostructured titanium dioxide film as a photoanode. Dye-sensitized solar cells do not require silicon as a raw material, and have low cost, simple manufacturing process, and high photoelectric conversion rate. specialty. [0003] The dye-sensitized solar cell mainly includes a semiconductor electrode, a counter electrode, an electrolyte between the semiconductor electrode and the counter electrode, and an encapsulation material. The dye layer in the crystal thin film, the semiconductor electrode and the counter electrode are sealed by an encapsulation material to form a space for containing the electrolyte, and the electrolyte is contained in the space. Due to the complex internal physical and...
