"The Bird's Nest Water Cube, the Ice Ribbon, the National Theater for the Performing Arts and the Burj Khalifa in Dubai all have our Jinjing figures." Wang Xiaoming, deputy general manager of Tengzhou Jinjing Glass Co., Ltd., told reporters,"Currently, our most prominent product in China or internationally is TCO photovoltaic conductive film glass, because this is a breakthrough in foreign 'stuck neck' technology. Previously, only Japan One line can be done. After we made a breakthrough, there are already three lines that can be done." Speaking of corporate technology, Wang Xiaoming is very proud.

Tengzhou Jinjing Glass Co., Ltd. is located in Tengzhou, Zaozhuang, and is a holding subsidiary of Jinjing Technology, a company listed on the main board. The factory has four high-quality float glass production lines using international advanced technology, mainly producing ultra-white glass of various specifications and models of 3-19mm, color glass, Low-E coated glass, TCO conductive film glass, etc., with an annual output of 18 million high-quality float glass. Weight boxes, high-end Low-E glass 10 million square meters, and TCO coated glass 15 million square meters. Jinjing has successively won titles such as "China Famous Brand Products","China Famous Trademark","Shandong Province Governor Quality Award" and "Shandong Province Famous Brand".

According to Wang Xiaoming, the construction of the Tengzhou second-line ultra-white TCO photovoltaic conductive film project will be completed and put into operation in October 2023. The single-line investment will be 350 million yuan, the designed production capacity will be 15 million square meters, and the annual output value will reach 800 million yuan, which can meet the requirements of 3GW of thin film photovoltaic cell production capacity such as cadmium telluride and perovskite. Four rounds of trial production and research and development will be carried out in the first half of 2024. In June, the products were successfully rolled off the production line, and batches of products have been sent to the United States. The TCO conductive film glass mentioned by Wang Xiaoming is a new type of glass material coated with a transparent conductive oxide film. It is mainly used in thin film batteries such as perovskite batteries and cadmium telluride. It is an irreplaceable material for this type of battery substrate, accounting for more than 40% of its cost. TCO conductive film glass is different from traditional photovoltaic rolled glass applied to monocrystalline silicon and polycrystalline silicon. It belongs to the special glass manufacturing technology of new materials. It is known as the "stuck neck" technology of the world's third-generation photovoltaic industry. Only Japan in the world. A company grasps it. After 20 years of research and development and spending 500 million yuan, Jinjing Group has successfully developed ultra-white TCO conductive film glass. It currently accounts for more than 90% of China's thin-film battery market share, achieving a zero breakthrough in this technology in China.
