KEY BENEFITS OF HETEROJUNCTION TECHNOLOGY (HJT)
THE TECHNICAL SUPERIORITY OF HJT ENABLES COST SAVINGS, MORE POWER AND HIGHER ENERGY YIELDS FOR END-CUSTOMERS
TECHNICAL SUPERIORITY
Cell efficiency of 24%: Exceptionally high efficiencies are achieved through combining
the advantage of crystalline silicon cells (c-Si) with their good light absorption and the
superior passivation characteristics of amorphous silicon (a-Si)

BENEFIT FOR END-CUSTOMER
Cost savings for BOS5 components, because higher efficiency technology requires less
modules/area for same power
B
More power, because higher efficiency technology deploys more power on same area
Temperature coefficient of -0.25%/K: The high passivation of amorphous silicon results
in an exceptionally low temperature coefficient; the possibility to use thin wafers for HJT
cells (e.g., 120 μm) can further reduce the temperature coefficient
Higher energy yield, because lower efficiency loss at operating temperature
Lowlight sensitivity: The amorphous silicon in HJT cells increases the cells ability to
capture a larger proportion of diffuse light than pure crystalline silicon cells
Higher energy yield, because more diffuse light is converted into electricity6
Relatively low first year (<2%) and annual degradation (<0.25%): Immunity to LID¹ of
the n-type silicon wafer and protection against PID2 through the extremely conductive
TCO³ that acts like a Faraday cage reduces year 1 and annual overall degradation
respectively
Higher energy yield, because actual efficiency remains closer to nameplate efficiency during lifetime
of technology
*
Exceptional bifaciality factor of >90%: The symmetric structure of HJT cells makes
them bifacial 'by nature', significantly increasing the bifaciality factor relative to bifacial
PERC cells (e.g., c. 75%)
Higher energy yield for bifacial modules, because more of the incident light on the rear surface can
be converted to electricity
1) Light-induced degradation; 2) Potential-induced degradation 3) Transparent conductive oxide; 4) Ratio of the nominal efficiency at the rear side, with respect to nominal efficiency of the front side; 5) Balance-of-system; 6) This impact is not accounted for in the value driver analysis and
business plan (upside potential)
