In recent years, JA Solar increasing costs of R & D, develop scientific research, independent research and development of solar cell conversion efficiency rising, costs continue to decrease and the international competitiveness of enterprises growing.

JA independent research and development of new monocrystalline solar cells Secium, the average conversion efficiency of 18.5%, highest 19.2%, the level of leadership in their domestic and foreign counterparts. In addition, the judge also continue to strengthen cooperation in R & D projects, such as the Energy Research Centre of Netherlands (ECN) and other world-class R & D institutions to develop solar cell conversion efficiency of over 20% of the battery.

Polycrystalline silicon solar cells are concerned, the improvement of the justice of poly production technology of solar cells and manufacturing technology, began to bring into production a new generation of polycrystalline silicon solar cells, the average conversion efficiency reached 16.6%, the highest conversion efficiency of over 17%. Production and use of technology efficiency of conversion of 16.2% over revenue, which is a big step forward, the components can increase solar energy production and reduce production costs. JA Solar and established a technology map clear the road, maintain the generation of transfer, research and development production, reserve generation, solar energy technology leadership in manufacturing.

JA developments suggest it will continue to walk in high efficiency solar cell technology and advanced line of commercial production.
