Our History

Sun harmonics is established in April, 2010 and located in Hangzhou. It’s mainly engaged in the research, sales and production of flexible CIGS thin film solar cells, optical electronic technology and relevant products. It also provides some consultation service before or after sales and it’s a new generation of photovoltaic technology system solutions provider.

The company was founded by a number of overseas high-level talents, its research team includes some internationally well-known scientists, who are senior research and development engineers of former Bell laboratory or other outstanding enterprises like Seagate and IBM. 

With the scientific research team‘s rich experience and superior capabilities in the development of new nano-material formula, system technology equipment, heat treatment technology, laser processing technology, non-destructive testing, new materials and new energy industry work,etc , the company successfully developed a new generation of flexible CIGS (copper indium gallium selenide) thin film solar cells and the core technology is in the world's leading ranks. The product has been certified by the Chinese Academy of Sciences photovoltaic and power testing center, its photoelectric conversion efficiency has reached 18% and batch finished module photoelectric conversion efficiency of more than 12%. It’s expected when the G-watt scale realizes, the final price of battery will be only 1/5 of the traditional solar cell, very close to coal prices, thus become quite competitive in the market.

Our Factory

The company has spared no effort to promote the transformation of scientific research products, now it has about 100,000 square meters of modern production base, complete production equipment and all production facilities for manufacturing flexible thin film solar cells. With its mature production technology and increasingly-improved management mechanism ,it has gone through the ISO9001: 2008 quality management system certification. Different from the traditional CIGS solar cell glass substrate production process, our stainless steel base roll on the roll coating process, can really achieve a standardized flexible CIGS thin film solar cell mass production.
