In this work we report first results of successful conversion of Hevel LLC micromorph production line to Si HJ technology with production kicked-off in Q1 2017. Implementation of in-house Si HJ cell technology developed by R&D Center TFTE using Gen5 (1.4 m2) KAI PECVD reactors with rear emitter bifacial cell design, O3 based IPA free texturing technology from Singulus, PVD tools and SmartWire module assembly line from Meyer Burger allowed to reach average cell efficiency of 21,7% with respective average 60 cell module power of 300W at production level and cell efficiencies as high as 22,77% at R&D. Achieved average module power after conversion from TF to Si HJ technology has almost doubled the annual line capacity from 97 to 160 MWp.
