Perovskite Solar Cell | Hejing Wins Bidding for an Energy Pilot Line Project in Guangdong

　　Perovskite photovoltaic cells in China have entered the eve of mass production. In the wave of continuous progress of photovoltaic technology, the iteration of solar cell technology is accelerating, and a perovskite structure material as a light-absorbing material of solar cells has attracted much attention, known as the representative of the third generation of thin film batteries, is the star material in the field of future photovoltaic BIPV, electric vehicle mobile power generation.

　　Compared with crystalline silicon batteries, perovskite batteries have the advantages of high conversion rate, low production cost, simple preparation process and high flexibility, which can be used in photovoltaic power generation, LED, mobile energy, intelligent 3C and other fields, and have broad prospects for development. At present, leading enterprises such as Beijing Oriental, Hete Optoelectronics, Ningde Times and Longji Green Energy have invested huge amounts of money to seize the opportunity of this emerging market.

　　With the increasing market scale of photovoltaic assembly machines, energy storage and lithium batteries, Hejing Intelligent Construction (Guangdong) Co., Ltd. has actively laid out, from lithium-ion batteries, power batteries to energy storage, crystalline silicon batteries, TOPcon, etc., to serve many excellent customers in the industry, and has accumulated rich experience in planning, design and construction, which has been recognized by many customers.

　　As perovskite solar cells have entered the key node of commercialization, the penetration rate of perovskite solar cells has also increased. As an important part of the production plant of solar cell industry chain products and a leader in the environmental construction of industrial plants, Hejing Construction actively develops its business market and strives to contribute to the development of the industry. Recently, Hejing Construction successfully won the bid for the clean plant construction project of perovskite solar cell pilot line of Guangdong Energy Technology Co., Ltd. It covers steel structure, heating and ventilation, electrical process, automatic control system, exhaust gas and so on. Hejing Construction will rely on the professional technology and rich construction experience of both sides, with "not built first", scientific planning, lean construction, and strive to build the industry benchmark future factory for customers.

　　The core business of the company is the research and development of large-area perovskite solar cell modules with high efficiency, long lifespan, and low carbon footprint. The current team has developed a large-area perovskite film printing technology with independent intellectual property rights, achieving the preparation of large-area perovskite components and leading the industry in comprehensive efficiency.

　　It is reported that the company has adopted an independent intellectual property ink formula project to solve the problem of perovskite crystallization from the source, improve the quality of perovskite crystals, and transform technical problems into engineering methods.

　　The person in charge of the Hejing Construction Special Group stated that the production process of thin-film cells is different from that of crystalline silicon cells. Thin film cells are another important branch of photovoltaic cell technology besides crystalline silicon cells, with high potential for conversion efficiency. One of the core production technologies of this project is airtightness, which achieves full packaging technology in a sealed environment to enhance the stability of perovskite cells. There are many professional contents involved in the construction of a clean workshop that conforms to its process. Hejing Construction mobilized a professional team to lead the project preparation. After multiple project discussions, the team worked overtime to quickly develop a full process construction solution that meets the requirements of the pilot line, which was highly recognized by Party A.

　　Mr. Mai stated that the signing of this project is an important breakthrough for Hejing Construction to explore the construction of perovskite (thin-film compound battery) factories, which has a positive impact on the company's opening up of the photovoltaic storage market.

　　Hejing Construction has always been driven by customer needs, taking technological innovation and lean management as important supports for the sustainable development of the enterprise, and contributing Hejing's strength to the development of the industry.
