Problem

Residential and light commercial PV markets continue to require high-efficiency but cost competitive PV modules in markets with FiT regression as well as unsubsidised emerging markets.

Solution

JA Solar’s PERCIUM cell has surpassed a conversion efficiency of 20.3%, 1.3% higher than average mono-Si” solar cells by 20W, according to the company. The cell efficiencies’ have been independently confirmed and certified by the Fraunhofer ISE's photovoltaic calibration laboratory (CalLab) in Freiburg, Germany, and sets an industry-leading mark for industrial size (156×156 mm2) solar cells using p-type mono-Si wafers. The PERCIUM module is claimed to produce 8% more power output per unit area than the average. It is claimed to produce 1% more power due to improved yield in low-light conditions. The company claims a reduction in transportation, installation and BOS costs.

Applications

The PERCIUM module is suitable for residential and commercial rooftops (small and medium-sized).

Platform

All its products are manufactured in-house, a procedure inspected and certified by PI-Berlin and Solar-IF. Apart from PID test, products of the company also passed long-term reliability tests, harsh climate environment endurance tests, and other tests certified by TUV, SUD and ETL. The PERCIUM cell employs a passivated, local back surface field (BSF).

Availability

February 2014 onwards.
