China-based monocrystalline module producer Shanghai Aerospace Automobile Electromechanical Co (HT-SAAE) has completed a production line upgrade from three- to four-busbar technology.
The company said upgrading to the four-busbar design reduced current pathway losses, boosting cell and module efficiency. Although HT-SAAE did not provide efficiency figure gains, typically current loss reduction can be in the range of 10% when migrating from a three-busbar architecture to four with an overall module power increase of 5W and more.
HT-SAAE also noted that it expected improved product reliability through reducing the risk of hotspot generation via micro-cracks as there would be less residual stress on the busbars.
Vice president of HT-SAAE, Shi Lei said: “We made quite an effort to complete the production line upgrade before Renewable Energy 2015 India, in hopes of providing the best products to our strategic markets such as India. India is the next key market for HT-SAAE to put efforts on, HT-SAAE is quite optimistic about Indian PV market outlook and have already employed a local sales team. We are expecting a more promising future in India.”
Earlier this year HT-SAAE launched a high-efficiency N-type monocrystalline bifacial module using PERT technology that was said to have minimal LID degradation with very good long wavelength response for higher electricity generation.
