Glass, arguably one of the greatest inventions of mankind.
From helping our windshield windows to important pieces of electronic information, the glass shines with irreplaceable light.
But have you ever seen a glass that can generate electricity yourself?
Recently, returnees Dr. Chengdu, China Building Materials Photoelectric Materials Co., Ltd. General Manager Pan Jingong and his team led it to become a reality:
A piece of 1.92 square meters weighing 30 kilograms of 'power generation glass' can generate electricity nearly 300 degrees per year, if used on two or three, it basically can meet a family annual electricity!
Oil fields hanging on the wall
Power generation glass, also known as cadmium telluride thin film solar cells, known as 'hung on the wall of the oil field'!
Each Xiao Bian learned that the production of a 1.6 meters long and 1.2 meters wide power generation glass, only 55 seconds, while its photoelectric conversion efficiency is as high as 17.8%, comparable to the traditional traditional silicon solar panels. Even the light is very Weak cases, but also through the photoelectric conversion of electricity.In other words, three or four thousand this glass produces electricity, equivalent to a normal oil wells a full year of oil can convert electricity.
On January 17, Yin Xinjian, party secretary of Chengdu Building Materials Optoelectronic Materials Co., Ltd., in an interview with Rongcheng Government (Wechat: znaitz) said that the glass from colorless to yellow then black is the process of installing the battery power generation process The formation of the battery, because the power generation layer coated Yin Xin explained:
Thin-film low-power glass products are plated on ordinary glass of cadmium telluride photoelectric materials, so that ordinary glass from the insulator into a conductive conductor, and then become a building material can generate electricity to achieve an organic combination of glass and materials. Block power generation layer of glass after laser etching, the formation of 214 small batteries in series, that is, visible on the black glass white lines .One piece of glass, through the back electrode junction box to collect electricity, can generate electricity, Into the inverter can be used directly.
Previously, the world's largest monolithic cadmium telluride thin film power generation glass is 0.72 square meters, has not been able to achieve a breakthrough.We should be 4 microns thick, equivalent to one percent hair thickness of cadmium telluride thin film uniform and uninterrupted Placed on the glass, the difficulty is very large.
According to the Sichuan Daily's earlier report, Pan Jin Gong promoted the supply revolution of the traditional glass industry in more than six years: breaking the monopoly of foreign giants and transforming the flat glass from building materials into functional materials capable of generating electricity and filtering. The building exterior Become a 'power station'.
Gu Zhen'an, an academician of the Chinese Academy of Engineering, commented that this laid the foundation for China to upgrade itself from a large building material glass powerhouse to a powerful electronic glass powerhouse and strong country for semiconductor materials.
