On January 18, Longi Le Ye announced that the independent third-party certification and testing organization TUV SUD (TUV-SUD), Longi Le Ye 60 high efficiency PERC module photoelectric conversion efficiency of 20.41%, creating a new single crystal PERC module conversion efficiency world record.

It is understood that Longji Le Ye test for P-type single crystal PERC components, relying on efficient PERC battery technology and component innovation design ideas, to achieve the highest component conversion efficiency of 20.41%. It is worth paying attention to that this data is one-sided efficiency, and the technical advancement is at the leading level in the industry.

In recent years, with the increasing demand for high conversion efficiency solar modules in the photovoltaic market, photovoltaic high conversion efficiency technology has developed rapidly. In the Chinese market, under the guidance of the application leader and technology leader project, the photoelectric conversion efficiency competition is extremely fierce, and all mainstream enterprises are constantly refreshing the highest battery efficiency and component efficiency.

Most photovoltaic enterprises pay more attention to improving the power of modules, mainly by improving the battery efficiency and increasing the spacing between modules, which will inevitably affect the efficiency of modules. How to strike a good balance between high power and high efficiency, to meet the needs of customers with the optimal component efficiency and system efficiency, is the key problem that PV enterprises need to be committed to solve in the research and development of efficient modules.

Longji Leye President to election day lee said, longji le leaf efficient single crystal conversion efficiency world record in the PERC components, for the first time on the efficiency of the component made a major breakthrough, we will through continuous technological innovation, for the single crystal components market brings more efficient products, help photovoltaic investors earn more power, contributing to construction of clear water, blue sky.

In September 2017, the National Energy Administration proposed in the "Notice on the Requirements of Promoting the implementation of the" Leader "Plan for photovoltaic power generation and the construction of the Leader Base in 2017" that the photoelectric conversion efficiency of polycrystalline and monocrystalline silicon cell modules of the leader base should reach 17% and 17.8%, respectively. The photoelectric conversion efficiency of polycrystal and single crystal battery components should reach 18% and 18.9% respectively in the technology leading base.

According to this requirement, the 60 type PERC single crystal module published by Longi Le Ye fully meets and greatly exceeds the technical threshold limit of "technology leader". It is also understood that the current mainstream manufacturers launched 60 single-side high power components conversion efficiency is mostly concentrated in 17.9% to 19.86%.

Longji Le Ye vice President lu, "said Dr Longji Le Ye efficient single crystal components will effectively help leader of project construction, higher power generation efficiency of components, which will produce more power in plant life cycle, the corresponding KWH cost will be lower, it will bring higher returns to investors hydropower station, longji le leaf efficient single crystal components will be leading project optimization.

Previously, Longi Le Ye announced in October 2017 in Beijing, Germany's Fraunhofer ISE CalLab test certification, the company's single crystal PERC cell photoelectric conversion efficiency of 22.71%, a new PERC battery world record. Ten days later, the record was 23.26%, breaking the industry's consensus of 23% efficiency for PERC cells.

Recently, Longi Le Ye has introduced PERC battery technology with a 22% efficiency level to the production base, in order to mass produce photovoltaic products that meet the leading technology standards. Longji Le Ye said that while the efficiency of the module has reached a new high, in 2018 the company will stack new technology of the module to achieve higher module power, so that high efficiency and high power go hand in hand, and bring greater value return for the photovoltaic application market, leading the early advent of the photovoltaic affordable Internet era.

1月18日，隆基乐叶宣布，经独立第三方认证测试机构TÜV南德（TÜV-SÜD）测试，隆基乐叶60型高效PERC组件光电转换效率达到20.41%，创造了新的单晶PERC组件转换效率世界纪录。

据了解，隆基乐叶本次测试的为P型单晶PERC组件，依托高效PERC电池技术及组件创新设计思路，实现了最高20.41%的组件转换效率。值得关注的是，这一数据为单面效率，技术先进性处于业内领先水平。

近几年来，随着光伏市场对高转化效率太阳能组件的需求不断增大，光伏高转化效率技术快速发展。中国市场上，在应用领跑者、技术领跑者项目的引导下，光电转换效率竞争异常激烈，各家主流企业都在不断刷新最高电池效率及组件效率。

大多数光伏企业更多关注组件功率提升，主要是通过提高电池效率及增加组件片串间距实现的，而这势必会影响到组件的效率。如何在高功率和高效率之间做好平衡，以最优组件效率和系统效率来满足客户的需求，是光伏企业高效组件研发中需要致力于解决的关键问题。

隆基乐叶总裁李文学表示，隆基乐叶高效单晶PERC组件转换效率世界纪录诞生，首次在组件效率上作出了重大突破，我们将通过持续的技术创新，为市场带来更加高效的单晶组件产品，帮助光伏投资者赚取更多的发电收益，为碧水蓝天建设贡献一份力。

2017年9月，国家能源局在《关于推进光伏发电“领跑者”计划实施和2017年领跑基地建设有关要求的通知》中提出，应用领跑基地多晶、单晶硅电池组件的光电转换效率应分别达到17%和17.8%以上，技术领跑基地多晶、单晶电池组件光电转换效率应分别达到18%和18.9%以上。

根据这一要求，隆基乐叶本次公布的60型高效PERC单晶组件完全满足并大大超过“技术领跑者”技术门槛限制。另据了解，目前主流厂家推出的60型单面高功率组件转换效率大多集中在17.9%至19.86%之间。

隆基乐叶副总裁吕俊博士表示，隆基乐叶高效单晶组件将有效助力领跑者项目建设，更高的组件发电效率，在电站生命周期内将产生更多电量，相对应的度电成本也会越低，这将为电站投资者带来更高回报，隆基乐叶高效单晶组件将是领跑者项目的优选。

此前，隆基乐叶在2017年10月于北京宣布，经德国弗劳恩霍夫太阳能系统研究所(Fraunhofer ISE CalLab)测试认证，公司单晶PERC电池光电转换效率达到22.71%，创下新的PERC电池世界纪录。10天之后，再次将纪录刷新至23.26%，打破了行业普遍认为的PERC电池可量产效率23%的极限。

近期，隆基乐叶已经将22%效率水平的PERC电池技术导入生产基地，以批量生产满足领跑者前沿技术标准的光伏产品。隆基乐叶表示，在组件效率再创新高的同时，2018年公司将叠加组件新型技术，实现更高的组件功率，做到高效、高功率齐头并进，为光伏应用市场带来更大的价值回报，引领光伏平价上网时代的早日来临。
