Polymer material solutions provider Cybrid Technologies supplies the global PV industry with its solar backsheets. Recently, while speaking on day 3 of the 4-day TaiyangNews High Efficiency Solar Technologies 2024 Conference, the Senior Manager Marketing for Cybrid Technologies, Anurag Mishra pitched the company’s proprietary RayBo film for TOPCon presenting it as the solution to the technology’s UVID issue thereby improving its performance and financial returns. Mishra shared RayBo’s origins saying in its original form, it was invented by Dr. Onouchi Hisanari in 2013 and patented by Nitto Denko. Cybrid started developing it further, supported by Nitto Denko. Since 2023, Cybrid has been producing RayBo under exclusive rights for its commercialization from CHOSHU that bought the patents from Nitto Denko for the UV conversion agent and POE film. According to Mishra, Cybrid devised its RayBo film especially for HJT and TOPCon modules as a light wavelength conversion film, embedded into light-conversion agents into materials like EVA, EPE and POE. The way it works is through an orbital transition mechanism, converting UV light into visible blue light boosting energy generation. This way it offers protection to the solar module from damaging UV rays. Under damp heat (DH) tests, it has shown less than 10% degradation in its light-conversion ability even after more than 2,500 hours of exposure. This, he said, proves its usefulness in high-humidity environments like coastal areas. For TOPCon modules, Cybrid said its UV conversion film demonstrates up to 0.53% improvement in energy output, thus proving its ability to withstand environmental stresses. Mishra claimed that nearly all the HJT makers currently use its RayBo film while the trend is picking up among TOPCon makers as well. In India especially, all major tier I manufacturers are already testing this film for TOPCon production.For more presentation videos and conference summaries for all 4 days of the TaiyangNews High Efficiency Solar Technologies 2024 Conference, click here for days 1 and 2, and here for days 3 and 4.
