Presenting its MoNo 2 solar cell technology as providing a competitive edge to module makers on day 3 of the 4-day TaiyangNews High Efficiency Solar Technologies 2024 Conference was JTPV's R&D Manager Xinrui An. Solar cell manufacturer JTPV’s MoNo 2 solar cell technology empowers its customers to compete in the market, according to An as he claimed it maximizes customer ROI and enhances power generation efficiency.
The MoNo 2 cell incorporates advanced metallization, improved edge passivation, and rear optical optimization. Key advancements over MoNo 1 include half-cut edge passivation (HEP), super thin fingers, multi-busbar metallization, among others.
Use of narrower fingers with smaller spacing helps with reduced resistive losses in the grid, and allows for higher emitter sheet resistance. According to An, super thin fingers lead to a 0.1% efficiency gain with optimized contact patterns.
A popular choice of late, HEP is increasingly preferred by module manufacturers to reduce risk losses in modules. An claims that the use of HEP in its MoNo 2 solar cell increases power output by around 5W for both single-glass and double-glass modules.
Another technological advancement it uses is the wave back surface field (WBSF) that reduces parasitic absorption by optimizing rear passivation layer properties. It leads to improved cell characteristics and bifaciality by up to 90%. This works best for various applications including solar farms, and carports.
JTPV currently operates a 40 GW solar cell production capacity in China. It is now expanding overseas with a 5 GW solar cell production in Oman, construction ongoing.
