The development of heterojunction will attach great importance to the protection of intellectual property rights

Island effect refers to the local grid photovoltaic (pv) grid inverter composition from the main grid, and photovoltaic (pv) grid inverter in the local power grid continue to power a load of a electrical phenomenon. Islanding phenomenon will have serious consequences

& other; Several report made no mention of the heterojunction all intellectual property rights, are all talking about photovoltaic heterojunction technology trends and the future development, is it because the heterojunction intellectual property isn't worth mentioning? ” On March 20, 2019, the fourth heterojunction weeks dean waves in the host cell and equipment industrialization BBS when mentioned about the heterojunction and other intellectual property rights; Worry & throughout; 。

it is well known that HIT in 1992 by Japanese sanyo succeeded in preparation, and application for trademark registration. Panasonic, sanyo, continue to HIT the battery development, heterojunction patents expire in 2015. Technical barriers to eliminate, is our country to develop and promote heterojunction technology a good time. It is worth noting that before 2015, all without consultation allows you to use the patent technology behavior belong to infringement. And also, after the patent expires will lose the protection of technology, perhaps at the appointed time has the public knowledge technology, but also need to pay attention.

, the rapid development of photovoltaic industry in China inevitably comes with large and small episode. Technological innovation process, the patent disputes will more or less influence on the enterprise image.

recently, hanwha prosecution crystal and longji for patent infringement events. On March 6, 2019, hanwha said in a statement the crystal energy, longji shares and REC three companies violated its passivation technology patents, longji has said in a statement that longji products is inconsistent with the patent technology involved methods, the patent is ALD technique, and longji is PECVD technology technique. Crystal, REC hanwha's charges also lack of legal basis and technical basis for similar response.

the truth we declined to comment, but actually is a dominated by the interests of disputes evolution & other Patent disputes & throughout; 。 Yet it is not similar event & other Rare & throughout; 。 China is the absolute leader of photovoltaic industry, hanwha the tort photovoltaic directed at China's two giants, similar things is not the first time but will never be the last.

in 2014, the installation of photovoltaic components WestinghouseSolar ( Westinghouse solar) To the United States international trade commission ( ITC) , who want to investigate artest solar and ZepSolar patent infringement, trina solar also risks being affected. Although the Westinghouse solar referred to in the case of two patents have been rejected the United States patent and trademark office. Artest also said that just because the application was affected, and in artest's share of sales of products is less than one over one thousand, which cause a trouble but also have to say.

China pv industry in a leading position in the world, inevitably have & other; Tall trees catch much wind & throughout; Phenomenon appears, only pay attention to the protection of intellectual property rights in the process of research and development production, blaze new trails, to reduce similar events.

China is the world's largest solar photovoltaic producer and exporter, solar photovoltaic industry is a world leader in the long run. Photovoltaic products in the global capacity is greater than the market demand, China pv capacity most of the world's inventory. Chinese photovoltaic products need for digestion in the global market, and the rise of trade protectionism, makes disputes appear constantly, the United States boycott of huawei inverter event is a good example, China pv enterprises to cope with the trend of the psychological and technical preparation.

just like it in the 4th heterojunction cell and equipment industrialization on the BBS, from co. , LTD. Was power equipment and the new energy industry, chief analyst at Mr Wang Ge said: & other; Trade war mainly aims at is the price of before, after a trade war is a struggle for dominance of the technology. University of the United States to the scientific research institutes to study as a kind of resource, not only for study, will eventually be converted into a kind of productivity. We are doing some technical research and development in the process, you should consider these questions in advance. The patent is as good as a means of is a means to protect themselves. ”
