China state-owned aerospace firm, Shanghai Aerospace Automobile Electromechanical Co (HT-SAAE) has revealed verified record solar module efficiencies for both N-type PERT (passivated emitter, rear totally diffused) and P-type multicrystalline modules.
HT-SAAE said that TUV Rheinland had verified that its 60-cell (N-type PERT) modules employing 156mm x 156mm commercial monocrystalline wafers achieved peak output power (Pmax) of 335.6Wp. HT-SAAE claims this to be a new industrial record.
In tandem, HT-SAAE said that TUV Rheinland had verified 156mm x 156mm commercial P-type multicrystalline wafers in a standard 60-cell format to achieved peak output power of 310.5Wp.
Doctor Zhang Zhongwei, CTO of HT-SAAE said, “To realize sustainable business and become a global first-class enterprise with leading technology is the mission of HT-SAAE. Since the 1960s, HT-SAAE has spent half a century gaining abundant experience in the photovoltaic industry. With R&D as its starting engine and lean production as the core competency, HT-SAAE has realized remarkable quantity of high quality projects worldwide.”
The modules are part of HT-SAAE’s in-house developed ‘HIGHWAY Plus’ PV module series that the company said would be commercially available in key markets around the world and will be first featured at Japan's 2015 PV EXPO tradeshow.
Although cell technical details were limited, HT-SAAE noted that it still employed ‘upgraded’ conventional bus bars and a solar cell matching technique, which was claimed to improve efficiency by reducing electricity loss.
The cells also included a ‘light trapping technique’ to enhance optical absorption, and advanced integration packaging technology at module assembly stage.
HT-SAAE has been supplying modules to various PV projects in China and overseas after establishing in 2010 a dedicated solar division with over 700MW of capacity and is venturing further to become an internationally recognised player.
