ApplicationCybrid’s RayBo film has been adopted by several HJT module manufacturers, including Maxwell and Huasun. A comparative analysis of power output variations between HJT modules using high-transmittance films, UV-cut-off films, and UV-conversion films revealed that while transparent films deliver high output, they tend to be less durable. In contrast, UV-cut-off films are durable but do not provide the same high output. RayBo, however, strikes the perfect balance, offering both reliability and performance, resulting in a 1.5% power gain per module. Additionally, the Huasun HJT module, which incorporates RayBo light conversion film, demonstrated less than 5% power degradation in an extended UV stress test (3 x IEC), further substantiating the film’s long-term reliability. Along with higher UV stress resistance, Cybrid’s comparative analysis of the extended damp heat (DH2000) test between Huasun’s UV-cutoff and Raybo film HJT modules showed that both exhibited the same level of output decay, demonstrating resilience under prolonged damp heat conditions. However, the Raybo film module exhibited higher output power than the UV-cutoff films, likely due to the Raybo film’s superior blue light transmittance property, added Mishra.Following recent trends of TOPCon modules degrading due to UV rays, Cybrid announces that it is extending the benefits of RayBo encapsulant’s ability to absorb UV light, convert it into visible light, and protect the module to TOPCon modules. Cybrid’s internal data shows that while the RayBo film’s UV cut performance is comparable to that of UV cut films, increasing the concentration of UV conversion agents in the RayBo film enhances its UV cut performance. This improvement is attributed to RayBo’s more than 100% blue light transmittance. Additionally, the TOPCon module combined with RayBo UV light conversion film has demonstrated measurable power increases, with up to a 0.53% improvement in energy output compared to the standard high-transmittance film module. It shows that this has a significant impact on the overall ROI of large-scale projects, explains Mishra.
