Trina Solar says it has begun evaluating potential infringements of a few of its patents for tunnel oxide passivated contact (TOPCon) tech. One of the patents focuses on the variety of busbars and their width in TOPCon photo voltaic panels.
Chinese photo voltaic module maker Trina Solar is actively making an attempt to find out whether or not different producers are presently infringing a few of its patents for TOPCon photo voltaic cell expertise.
“In Trina’s opinion, it’s essential to create a good ecosystem the place mental safety performs an essential function,” the overall director of Trina Solar for Latin America and the Caribbean, mentioned pv journal. “What Trina finds troublesome to simply accept is that some firms entry this ecosystem illegally or by avoiding investments.

Our patented expertise clarifies the ratio between the variety of busbars and their width, optimizing the output effectivity of photo voltaic cell modules. It additionally maximizes the conversion of photo voltaic vitality into electrical vitality, whereas making certain the steadiness and longevity of the answer that may stand up to years of operation.
García-Maltrás additionally mentioned that the manufacturing of TOPCon panels required a sequence of patents.
“I do not suppose any producer has developed 100% of the patents it makes use of in manufacturing,” he mentioned. “There are agreements between producers who wish to cooperate and wish to shield R&D investments. This is the form of industrial atmosphere that we wish to assist.”
Trina’s current transfer follows First Solar’s announcement final week that it’s investigating potential infringements of its TOPCon patents. First Solar secured the patents by its acquisition of TetraSun in 2013.
Bill Mulligan, CEO of Singapore-based IBC photo voltaic module maker Maxeon, additionally spoke pv journal in June that the corporate is able to implement the mental property rights of all present and new back-contact (BC) rivals who allegedly use its applied sciences.
In February, Trina Solar and its South Korean rival, Hanwha Qcells, reached an settlement to settle a patent dispute launched by the Chinese module maker in January. In a joint assertion, the 2 firms mentioned they’ve reached a patent licensing and switch settlement on their mental property.
