China’s path to innovate solar encapsulation materials

Zhao Shijie, majoring in chemistry, failed to expect that a profession will be begun by him in photovoltaic encapsulation materials upon graduation. Despite being in his 40s, Zhao was operating companies within the solar industry across Asia for over 2 full decades and has now his own success tale that is solar.

Witnessing the development of solar encapsulation materials in China, Zhao experienced the time of reliance on encapsulation materials imported from international nations about 20 years ago.

Influenced by Ding Kongxian, founder of shenzhen-based power that is new Jiawei, additionally initial business to perform solar lights business in China, Zhao began exploring encapsulation materials of solar panel for lights.

He had been cobbled as he founded Dongguan Yonggu Insulation Material Co in 1998 to r&D that is complete epoxy resin glue for solar lights panels due to the fact industry was totally blank then. Upon 100 failed experiments, Zhao finally exercised a glue known as 111A/B, which dominated industry that is domestic years later on, Zhao stated.

Since 2000, medium- and small-sized companies that are solar sprung up like mushrooms after a springtime rain, regardless of the country’s solar industry still being in its initial stage.

A type of material utilized in photovoltaic modules encapsulation, were monopolized by some key manufacturers including Specialized tech Resources (STR) from the US, Mitsui Chemicals and Bridgestone from Japan, and SKC and Hanwha from South Korea throughout that time, EVA.

Up against such conditions, domestic component factories had to manage issues such as for instance high costs, extended distribution time and after-sales woes. As one of the marketing participants, Zhao saw advertising potential and hoped which he could resolve dilemmas for his consumers.

Zhao wanted to copy their successes which are previous started his exploration on EVA materials, which tend to be softer and more expense effective than plastic. Issue, “How can the monopoly is broken by us of international companies?” confused Zhao for a long time.

Breaking the monopoly

Zhao then founded a company that is brand new Jiangsu Sveck New Materials Co in 2005 to perform EVA R&D. Zhao and his group lived in the factory and went every where to seek materials which are suitable. They drew design paper and did welding by themselves simply because they could not get required equipment for production.

Throughout the Chinese Spring Festival that 12 months, Zhao and their group consumed noodles that are immediate order to resolve their tech issues. After failing tens of thousands of times, they eventually succeeded.

Nevertheless, he came across problems that are brand new because so many customers doubted the caliber of their products. Zhao recalled that certain of their consumers told him that their company would make use of Zhao’s items only when the leading solar-panel that is chinese during those times (Suntech Power) respected their products.

Zhao afterward understood the importance of production line self-design and mastered formula know-how. Upon completing multiple tests being strict Zhao’s EVA materials finally got the commercial leaders’ recognition and later brought Zhao success, making their company one of the leading EVA providers globally.

Meanwhile, Zhao comprehended the lack of EVA commercial requirements in Asia ended up being one of many reasons that domestic elements businesses only trusted suppliers which can be international. As well as other product that is solar, energy channels along with other relevant participants, Zhao drafted EVA industrial standards and its own relevant evaluating requirements in order to manage the industry.

Under the guidance of commercial policy and driven by market need, China’s photovoltaic industry has accomplished development that is quick and has become mostly of the companies that has advantage on its global competitors, in accordance with a study released by the Asia Photovoltaic business Association (CPIA) in February.

As vice manager associated with photovoltaic auxiliary materials and elements items committee under CPIA, Zhao noted that the industry should avoid overcapacity as upstream and downstream companies need healthy competition; and, just with advanced technology can the industry keep a task globally that is leading.

Particularly for key equipment and materials, domestic companies should enhance cooperation and coordination to avoid limitations by foreign nations.
