In order to improve the competitiveness of photovoltaic products, one of the most effective ways is to increase the conversion efficiency of solar cells. In addition to improving the conversion efficiency of the cell itself through various technical means, considerable progress has also been made in improving the light transmittance and weather resistance of its packaging material-photovoltaic glass. The current mainstream technical solution is to coat the surface of the photovoltaic glass with an anti-reflection film, that is, use the sol-gel method to coat one or more layers of thin-film materials on the surface of the photovoltaic glass to reduce the reflection in a specific band of the spectrum, thereby improving the photovoltaic glass transmittance. The methods of coating the glass surface include roll coating, spraying, and surface etching, among which roll coating is the most widely used because of its convenient implementation.
However, all current technical methods cannot solve the problem of uniformity of the coating film. During the spray coating process, the coating solution in the center of the spray gun is more enriched, causing mottling; the surface etching method is difficult to uniformize the surface composition of the embossed glass, resulting in inconsistent etching reaction speeds and uneven film thickness;
Glovebox evaporation all-in-one machine. This system is integrated by the vacuum coating system and the glove box system, which can complete the film evaporation in the high vacuum evaporation chamber, and store and prepare the samples under the glove box high purity inert gas atmosphere and the detection of samples after evaporation. It is mainly used in experimental research and application of solar cell perovskite, OLED and PLED, semiconductor preparation, etc.
The combination of evaporation coating and glove box realizes the fully enclosed production of evaporation, encapsulation, testing and other processes, so that the entire film growth and device preparation process is highly integrated in a complete controllable environment atmosphere system, eliminating the organic large-area circuit preparation process. The influence of unstable factors in the atmospheric environment guarantees the preparation of high-performance, large-area organic optoelectronic devices and circuits.
