第二届N型晶硅电池与双面发电论坛/2nd N-Type c-Si Cell and Bifacial Module Forum 2017

第二届N型晶硅电池与双面发电论坛/2nd N-Type c-Si Cell and Bifacial Module Forum 2017

很高兴向您介绍将于2017年12月12日在常州召开的“第二届N型晶硅电池与双面发电论坛”。

N型晶硅电池主要包括N-PERT/N-PERL电池、叉指状背接触电池(IBC)和异质结电池三大类。相比P型晶硅电池，N型晶硅电池的少子寿命高，无光致衰减，弱光效应好，温度系数小，是晶硅太阳电池迈向理论最高效率的希望。2016年9月，应用异质结和背接触技术，日本Kaneka公司HBC电池效率达到创纪录的26.33%。ITRPV 2017预测N型硅片的市场占有率将持续增加，2019年超过10%，2027年将超过26%。

N-PERT和N-PERL电池结构简单，效率提升潜力大，而且可以实现双面发电。英利、中来和航天机电等已经实现了N型单晶双面高效电池的量产。双面发电可以实现10%-30%的发电量增益，曾是N型电池独有的优势，但现在也在受到P型PERC双面电池的挑战。此外，N-PERT和N-PERL电池产线还可以在现有P型产线基础上升级改造而成，最大程度保留和利用现有设备和工艺，节省投资。

异质结电池是距离实现大规模量产最近的下一代太阳电池技术，其优势不仅在于能量转换效率高，还在于简单的低温制造工艺、薄硅片应用、温度系数和CTM低、可双面发电等。松下已实现异质结电池HIT系列组件的量产。2016年12月，福建金石能源6×100MW异质结电池产线投产;2017年5月，晋能集团2GW异质结电池及组件项目一期投产。随着产能扩张，异质结电池成本下降空间值得期待。

IBC电池P-N结和电极全部在背面，完全消除了前表面栅线的遮光，量产平均效率可达23%。但IBC电池对硅片质量要求高，且制程复杂，因此成本高昂。在制备过程中使用工业化技术，例如丝网印刷、管式扩散或离子注入，是实现IBC电池低成本的关键。中来规划10GW N型单晶IBC双面太阳电池项目，一期3GW将在2017年底前开工建设。

第二届N型晶硅电池与双面发电论坛将于2017年10月26日在江苏常州召开。会议将探讨光伏行业展望与N型电池和双面发电市场，N型硅片品质提升与成本下降前景，N-PERT/N-PERL电池、异质结电池与IBC电池技术进展与规模化生产，N型电池性能提升潜力与成本下降路径，N型电池金属化工艺与先进导电浆料，双面发电组件系统优化与真实发电收益等。

Dear Sir or Madam:

N-type c-Si solar cells mainly include N-PERT/N-PERL cell, interdigitated back contact (IBC) cell and heterojunction (HJT) cell. Compared to P-type c-Si cell, N-type c-Si cell has high minority carrier lifetime, no light-induced attenuation (LID), good low-light effect, low temperature coefficient, is expecting towards the theoretical highest efficiency of c-Si solar cells. In Sep. 2016, Kaneka’s HBC (HJT+IBC) cell efficiency has achieved a record of 26.33%. ITRPV 2017 forecasts N-type silicon wafer market share will continue to increase, with more than 10% in 2019, and more than 26% in 2027.

N-PERT and N-PERL cells have simple structure, large potential to enhance efficiency, and can achieve bifacial power generation. YingLi, Jolywood and HT-SAAE have been achieved mass production of high efficiency N-type mono-Si bifacial cell. Bifacial modules can achieve 10% -30% power generation gain, once was the unique advantages of N-type cell, but now challenged by the P-type bifacial PERC. In addition, N-PERT and N-PERL cell production lines can be upgraded from existing P-type lines, maximally retain and use the existing equipment and processes to save investment.

HJT is the next generation of solar cell technology that is closest to mass production. It has advantages of high conversion efficiency, simple low-temperature manufacturing process, thin wafer applications, low temperature coefficient and CTM, bifacial power generation. Panasonic has achieved mass production of HIT series modules. In Dec. 2016, Fujian Jinshi Energy started up 6×100MW production lines. In May 2017, Jinneng Group’s 2GW HJT cells and modules Phase 1 project put into operation. With the capacity expansion, cost reduction space of HJT cells is worth expecting.

IBC cell’s P-N junction and electrodes are all on the back, completely eliminating the gate line shading of front surface, the average mass production efficiency is up to 23%. But IBC cell requires high quality wafer, and production processes are complicated, so the cost is high. Using industrial technologies in the production line, such as screen printing, tube diffusion or ion implantation, is the key to achieving low cost IBC cell. Jolywood has planned 10GW N-type bifacial IBC cell project, 3GW will start construction by the end of 2017.
