tunnel oxide passivated contact

JA Solar has announced a plan to construct a project in the Ordos High-Tech Zone, with an annual production capacity of 30GW ingots, 10GW silicon wafers, and 10GW modules. The total investment amounted to about RMB6.02 billion (US$870.1 million). 

Chinese module manufacturer Jolywood has claimed that it had achieved a power conversion efficiency of 26.7% for its n-type M10 (182mm) solar cell.

Solar module manufacturer Seraphim Energy Group has launched a new TOPCon (tunnel oxide passivated contact) series of solar PV modules.

German research institute Fraunhofer ISE has claimed a new record conversion efficiency for a 20mm x 20mm N-type multicrystalline cell using process match wafer and its TOPCon (Tunnel Oxide Passivated Contact) developed technology.
