GAME CHANGING TECHNOLOGY
A simplified manufacturing process and high efficiency cells make HJT a game-changing, commercially-proven technology. With significantly less degradation than PERC and TOPCon modules, HJT provides new levels of reliability and lifetime value. Plus, HJT cells are more efficient than PERC or TOPCon cells, requiring fewer modules and less acreage for a given project size (on a MW basis).
HJT enables a longer runway of technological superiority and increases the share of automated manufacturing functions. Less equipment is needed compared to TOPCon cells, taking up less space in a facility, and a simplified process reduces the amount of labor required, reducing operating costs and lowering the burden of training a new workforce, substantially reducing startup risk.
Since HJT had not been commercialized at scale until very recently, Calypso was taking a ‘wait-and-see’ approach with regards to the technology. Now that there is clear proof and success of it being implemented at scale, Calypso has decided to take advantage of this innovative technology.
BENEFITS OF CALYPSO’S HJT MODULE
To meet the strong demand for highly-efficient HJT modules, over 17 GW of HJT module factories are already operational globally. Based on sustained customer demand for the efficiency, longevity, and reliability of these modules, more HJT factories are being built with 66 GW of HJT factories expected to be operational by the end of 2023 and even more in 2024, including Calypso’s initial 3 GW cell and module factories.
HIGHER EFFICIENCY LEADS TO HIGHER POWER
DENSITY AND LOWER CONSTRUCTION COSTS
Due to high module efficiencies exceeding 23%, HJT modules produce more power per square meter than PERC modules which only have efficiencies of up to 21.5%. A solar project built using HJT modules could use 20% fewer modules than a PERC project and save on Balance of System costs including fewer trackers, piles, grading, and electrical cables, all while using 7% less land, which decreases lease and vegetation management costs throughout the lifetime of the project. Alternatively, higher-capacity projects can be built on the same land area to increase revenues without the risk of finding and permitting additional land.

LIFETIME PERFORMANCE
HJT modules have a lower warranted annual degradation of 0.25% compared to the 0.45% annual degradation of PERC modules and 1% lower first year degradation. After 30 years of operations, HJT modules could still produce 91.5% of their nameplate power capacity while PERC modules would only produce 84.5% of their nameplate power capacity after 30 years of operations..
TEMPERATURE COEFFICIENT
HJT modules perform better in higher temperatures than PERC modules due to their lower Maximum Power Temperature Coefficient of -0.24%/⁰C compared to PERC’s -0.34%/⁰C. A smaller negative temperature coefficient for HJT modules means that there will be a smaller decrease in how much power HJT modules can produce in hot environments, thus maximizing all-day power generation of solar projects.
BIFACIALITY
HJT modules have a bifaciality factor of approximately 90%, compared to typical bifaciality factors of 65-70% for PERC modules, which leads to an average HIT bifacial energy gain of 5-9% for projects compared to a typical PERC bifacial energy gain of 4-7%.
PRODUCTS DESIGNED WITH PURPOSE
FWe are launching with Calypso Hermes line of heterojunction solar modules to meet the most pressing needs of utility scale, commercial & industrial, and community solar projects with two available sizes—the CALYPSO HERMES HJT 695-715W 66 CELL module and CALYPSO HERMES HJT 630-650W 60 CELL module—built to capture the maximum amount of solar energy and maintain that high performance throughout its lifetime.

66 CELL HALF-CUT BIFACIAL MODULE
N-type HJT technology for lower LCOE
The higher efficiency, lower temperature coefficient, and better low irradiance performance of HJT technology can effectively reduce LCOE.
Class A Fire Rating, harsh environment adaptability
The back of the dual-glass module uses highly transparent glass, which can adapt to all kinds of harsh environments, and the fire rating can reach Class A.
30-year power warranty
The average life of dual-glass modules is 30 years, 5 years longer than that of single-glass modules.
Double-sided power generation, higher income
The dual-glass HJT module are designed for 90% bifaciality, compared to typical PERC bifaciality of 65-70%, leading to a 25-40% higher bifacial gain.

INCREASED POWER DENSITY AND ENERGY PRODUCTION GENERATES VALUE ACROSS THE US
Projects that use HJT modules will benefit from increased power density, which lowers construction costs, and increased lifetime capacity factor, which increases energy production. Regardless of location, the value delivered will be signification. For two typical US projects, one in the Northeast and one in the Southwest, additional value creation is estimated to be between the range of $0.09–$0.19/Wp.
