This week pv magazine was in Amsterdam for the sixth edition of the BifiPV workshop, where the discussion focused on the impressive achievements made by bifacial solar modules and the challenges the technology faces as it moves toward mainstream adoption.

Among n-type manufacturers, SunPower, Panasonic, and LG had the leading roles in interdigitated back contact (IBC), heterojunction (HJT), and tunnel oxidized passivated contact (TOPCon), respectively. But Chinese cells with low cost and high efficiency trends have been on the rise. In the future expansion of n-type production lines, the power of Chinese cell manufacturers and equipment makers can’t be underestimated.

The PV maker plans to shift its 800 MW of E-Series production to its new NGT technology, as it records a massive loss on depreciation of its old equipment. The move was revealed in second-quarter figures featuring plenty of red ink.

Trina Solar has set a new record of 25.04% total area efficiency for an n-type interdigitated back contact (IBC) solar cell. The record has been independently verified by Japan Electric Safety and Environmental Technology Laboratory.

The decorated PV pioneer will step aside from his role as Trina Solar’s VP and chief scientist on February 12 in order to devote more time to his family life.

A team of researchers from École polytechnique fédérale de Lausanne (EPFL) and the Swiss center for Electronics and Microtechnology (CSEM) has developed a new process for fabricating cells with all electrical contacts at the rear. According to EPFL, the process has already achieved lab efficiencies in excess of 23%.
