PVTIME - In 1Q 2020 Hevel Group has launched production of heterojunction
solar cells based on M2+ silicon wafers. A slight area increase has allowed to
raise the HJT solar cell peak power up to 5,88 Wp with maximum cell efficiency
rate of 23,8%, while maintaining an average of 23,3%.
At the same time Hevel HJT modules have retained their
respective dimensions, while receiving a boost in yield and efficiency thanks
to the M2+ transition. HJT modules with increased power output of 330 Wp and
390 Wp were introduced to existing glass-backsheet 60-cell and glass-glass
72-cell module series, respectively. Enhanced performance combined with
minimized annual degradation, better yield in hot climate conditions and
aesthetic appearance make these HJT modules a solid pick for any project, where
efficiency matters.
Thinking several steps ahead Hevel R&D centre in Saint
Petersburg, Russia, has already started testing M6 wafer-based HJT solar cells,
designed for multi-busbar / multi-wire interconnection technology. Hevel Group
expects the peak power for HJT solar cell based on M6 silicon wafer, which is
6% larger than M2, to reach at least 6,71 Wp. Hevel Group believes that in the
coming years there will be a surge in market demand for PV modules with highest
possible performance and Hevel will make sure that such a product is available
to its partners and clients.
