Efficient photovoltaic battery core technology lack of restriction authors

“ Authors efficiency & throughout; Is the developing direction of photovoltaic technology. On March 28, in & other; Efficient battery technology development and equipment application in 2019 conference & throughout; Photovoltaic industry, industry experts said, China is not only to take the lead in applying new technology, but also break the efficient battery the situation of the core technology of others, only in this way, can a boost as a decline in the cost of photovoltaic (pv).

according to introducing, theoretical studies have shown that silicon limit efficiency in 29. Around 4%, and the laboratory, polysilicon highest efficiency can reach 22. Efficiency of 9%, the single crystal is 26. 7%, close to the theory of limit. , artest sunshine power group chief technology officer XingGuoQiang said in an interview, solar component and equipment integration is relatively high, in the pursuit of efficiency at the same time, industrial feasibility and economic feasibility is issue to consider. “ Parity on the Internet and the efficiency of the component is not a simple relationship, reduce KWH cost, system cost is the key. ”

in the face of the technical requirements, in recent years, the efficient casting single crystal technology, efficient PERC battery technology, Topcon battery technology, efficient silicon heterojunction photovoltaic efficiency such as battery technology emerge in endlessly. Among them, in order to & other; The cost of the polycrystalline, efficiency of single crystal & throughout; For ingot casting of single crystal technology has received the widespread attention recently.

the GCL System Integration Technology Co. , Ltd. , chief Technology officer Zhang Chun introduction, after several years of upgrades, compared with czochralski single crystal, ingot casting single crystal obvious advantages in terms of low cost, decay resistance.

photovoltaic new material battery technology is also the focus of the industry. In mid-march, ministry of science and high technology research and development center issued a renewable energy and hydrogen technology proposed project project list for 2018, including both ends of perovskite/silicon laminated flexible copper indium gallium selenide thin film solar cells, solar cells, efficient P type and N type polysilicon batteries of controllable damping research subject.

in view of the ministry of science and the science and technology projects, crystal secco energy holdings co. , LTD. , vice President of jinhao said: & other; According to the current strategic thinking, advanced key technology and industrialization demonstration, advanced crystal silicon thin-film batteries industrialization of key technology, basic research new solar cells and photovoltaic modules recycling technology and equipment of photovoltaic battery technology will be the future development direction of the big four. ” More than

the expert points out, although our pv industry to realize the size of the shipments in the world, but it remains to be a breakthrough in the field of core technology and equipment. “ Topcon from r&d, the advanced battery technologies such as PERC is not independent research and development in our country, further enhance core parts localization rate is the key to the sustainable development of the industry. ” Jinhao said.
