第四届PERC太阳电池与双面发电论坛2018

 第四届PERC太阳电池与双面发电论坛2018

4^th PERC Solar Cell and Bifacial Module Forum 2018

 

钝化发射极和背面（PERC）技术正在成为太阳电池新一代的常规技术。制造工艺的成熟和较低的资本投入使PERC电池产能易于扩张，加上下游市场对高功率组件的需求，光伏行业积极扩张PERC电池产能。2017年全球太阳电池产能约125GW，其中PERC电池产能达35GW。2018年新建或升级的P型晶硅太阳电池产线，基本都将采用PERC技术。

 

与常规电池产线相比，PERC技术仅需增加背钝化和激光开槽工段，以及金属化工艺的适当配合，就能有效提升太阳电池转换效率。PERC技术使P型晶硅太阳电池的效率提升到以前无法想象的地步。晶科能源2017年10月宣布了创纪录的多晶PERC电池22.04%效率，隆基乐叶2018年2月宣布了创纪录的单晶PERC电池23.6%效率。

 

PERC技术的优势还体现在与其他高效电池和组件技术兼容，持续提升效率和发电能力的潜力。通过与多主栅、选择性发射极和TOPCon等技术的叠加，PERC电池效率可以进一步提升；组合金刚线切割和黑硅技术，可以提高多晶电池性价比。而双面PERC电池在几乎不增加成本的情况下实现双面发电，在系统端实现10%-25%的发电增益，极大地增强了PERC技术的竞争力与未来发展潜力。

 

与此同时，PERC产线设备的持续完善和国产化，以及适用于PERC工艺的导电浆料和金属化技术的不断进步，也有利于PERC技术的推广应用，PERC单晶与多晶电池量产效率近期将普遍超过22%和21%。但PERC电池要保持竞争优势，仍然需要进一步提升转换效率，降低成本，提升良品率，并解决光致衰减（LID）问题。

 

第四届PERC太阳电池与双面发电论坛将于2018年6月28日在江苏无锡召开。会议将探讨全球与中国光伏行业展望与PERC技术前景，多晶与单晶PERC电池的竞争力分析与市场份额，PERC电池产线优化与关键技术装备，双面PERC电池技术挑战、测试标准与背面发电优化，双面PERC电池组件实际发电投资回报，PERC电池LID机理与解决方案，PERC电池效率提升展望，PERC电池导电浆料与金属化工艺等。

Background

 

Passivated emitter and rear cell (PERC) is becoming the new generation of solar cell technology. Mature manufacturing processes and low capital investment make PERC capacity easy to expand, coupled with the downstream market demand for high-power modules, the PV industry to actively expand PERC capacity. In 2017, global solar cell capacity is about 125GW, including PERC capacity of 35GW. The new or upgraded P-type crystalline silicon solar cell production line in 2018 will basically use PERC technology.

 

Compared with the conventional cell production line, PERC technology can increase the solar cell conversion efficiency effectively by only increasing the rear passivation and laser grooving steps and the cooperation of the metallization process. PERC technology makes P-type crystalline silicon solar cell efficiency improved to unimaginable. In Oct.2017, JinkoSolar announced record-breaking multi-Si PERC solar cell efficiency of 22.04%. In Feb.2018, LONGi LERRI announced record-breaking mono-Si PERC solar cell efficiency of 23.6%.

 

The advantages of PERC technology are also reflected in the potential to be compatible with other high-efficiency cell and module technologies to continually improve efficiency and power generation. PERC solar cell efficiency can be further enhanced by using technologies such as MBB, selective emitter and TOPCon; combined diamond wire sawing and black silicon technology to increase the competitiveness of multi-Si cells. Bifacial PERC achieves double-sided power generation with almost no increase in cost and 10%-25% power generation gain at the system end, greatly enhancing the competitiveness and future development potential of PERC technology.

 

Meanwhile, continuing improvement and localization of PERC equipment, as well as the maturity of PERC metallization paste technology, are also conducive to the rapid application of PERC technology, and the mass production efficiency of mono-Si and multi-Si PERC cell recently will be more than 22% and 21% respectively. However, in order to maintain competitiveness, PERC cells need to further enhance the conversion efficiency and reduce costs, improve yield and commit to solving the problem of light induced degradation (LID).

 

4^th PERC Solar Cell and Bifacial Module Forum will be held in June 28, 2018 in Wuxi, Jiangsu, China. The upcoming conference will discuss global and China PV industry outlook and PERC prospect, competitive analysis and market share of multi-Si and mono-Si PERC cell, PERC solar cell production line optimization and key technology equipment, bifacial PERC solar cell technical challenges, test standards and rear side generation optimization, bifacial PERC module real power generation return on investment, PERC LID mechanisms and solutions, PERC solar cell efficiency improvement outlook, PERC solar cell paste and metallization technology, etc.
