Embodiment Construction

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0034] The application principle of the present invention will be further described below with reference to the drawings and specific embodiments.

[0035] Such as figure 1 Shown: A manufacturing method of natural dye-sensitized solar cells,

[0036] S101: Dye preparation: fully grind the purple cabbage in a mortar and transfer it to a beaker, add 25% ethanol solution until it is submerged, seal with plastic wrap, heat it in a 55℃ water bath for 2 hours, take it out and filter, and avoid the filtrate. Keep it light for 24 hours. The other plants use similar methods to adjust the ethanol ratio to obtain the best leaching r...

Abstract

The invention discloses a natural dye-sensitized solar cell apparatus and a manufacturing method thereof. The manufacturing method comprises steps of preparing dye, preparing a sizing agent, preparing photo anode, preparing an electrolyte, preparing a counter electrode by using a piece of graphite-plated conducting glass, and assembling a cell. Meanwhile, the invention also discloses a natural dye-sensitized solar cell apparatus. In order to overcome defects in the dye molecule, the manufacturing process, and the structural design of the dye-sensitized solar cell in the prior art, the apparatus and the process employ the available natural dye molecule with the low cost as a sensitizer and an ultraviolet curing resin encapsulation process is developed; and the non-woven fabrics are used to manufacture a diaphragm. Therefore, the cost of the dye-sensitized solar cell is reduced substantially; the power generating efficiency is improved; and the applicability of dye sensitization is enhanced.

Description

Technical field [0001] The invention belongs to the technical field of energy-saving batteries, and particularly relates to a natural dye-sensitized solar cell device and a manufacturing method thereof. Background technique [0002] Solar energy is a primary energy and renewable energy. It is not only rich in resources, but also clean and pollution-free. Solar cells can use sunlight to directly generate electricity. At present, the most widely studied and used solar cells are mainly silicon solar cells, but such cells have high raw material costs and complex production processes. Dye-sensitized solar cells (DSSC) have simple manufacturing processes, high photoelectric conversion efficiency, low light conditions, and cost about 1 / 5-1 / 10 of silicon cells, so they have higher application prospects. [0003] The working principle of dye-sensitized solar cells is similar to the photosynthesis of leaves. When sunlight irradiates the dye-sensitized solar cell, the dye molecules are exci...
