Advanced silicon raw material purification technology

Using JA Solar's proprietary technology to purify metallurgical grade silicon to make solar cells. Substantially upgraded silicon wafers produced by this technology are less expensive than those of electronic grade and make it possible to manufacture high quality silicon solar cells at low cost.

High‐efficiency crystalline‐based PV cells

Using various innovative approaches to develop crystalline silicon based solar cells with high conversion efficiency that can be mass produced in a cost‐effective way.

Large‐scale PV modules manufacturing technology based on the second generation cells

Partnering with equipment vendors in developing JA Solar's unique thin‐film based solar cell/module manufacturing process in large scale yet at low cost.

Long‐term research on more advanced third‐generation PV technology

Aims to decrease costs by significantly increasing efficiencies but maintaining the economic and environmental cost advantages of thin film and nanostructure based technologies.
