第五届PERC+ 与TOPCon技术论坛2019

 第五届PERC+ 与TOPCon技术论坛2019

5^th PERC+ and TOPCon Forum 2019

 

会议背景

 

钝化发射极和背面（PERC）技术已经成为太阳电池新一代的常规技术，2019年全球PERC电池产能将超过100GW。通过集成选择性发射极（SE）技术、先进浆料与金属化工艺等，2019年PERC电池量产效率已经达到22.5%以上。为了实现更低的生产成本，制绒与背面抛光工艺、背钝化工艺、激光工艺、导电浆料与金属化工艺的供应商们持续改进技术和设备，以提升设备生产能力和在线率，并降低物料和能量消耗。

 

与此同时，选择性发射极、多主栅和隧穿氧化层钝化接触(TOPCon)等技术也正在被引入标准PERC电池工艺，通过应用钝化接触技术，晶科于2018年实现创当时纪录的23.95%效率PERC电池。目前先进P型PERC电池最高效率已经提升到以前难以想象的24%以上。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。

 

对于N型电池，TOPCon技术通过电池背面的隧穿氧化层和掺杂多晶硅层实现整面的背钝化，而且多子可以穿透两层钝化层，无需开孔，避免了开孔处硅材料损伤和金属接触区域的复合。钝化接触技术也被认为是PERC电池极具潜力的发展方向，梅耶博格(Meyer Burger)开发了升级现有PERC产线的技术方案，可使PERC电池量产效率提升至23%以上。

 

第五届PERC+ 与TOPCon技术论坛将于2019年8月8日在杭州召开。会议将探讨全球与中国光伏行业展望与双面PERC市场份额，先进PERC技术的持续优化——SE技术、多主栅技术、制绒与背面抛光工艺、背钝化工艺、激光工艺、导电浆料与金属化工艺，24%以上效率PERC电池展望，单晶与多晶PERC电池LID和LeTID机理与解决方案，TOPCon技术在PERC电池的应用前景，PERC产线升级钝化接触技术的工艺方案等。

Background

 

Passivated emitter and rear cell (PERC) has become a new generation of conventional technology for solar cells. In 2019, global PERC cell capacity will exceed 100GW. PERC mass production efficiency in 2019 has reached more than 22.5% with selective emitter (SE) technology, advanced paste and metallization process. In order to achieve lower production costs, suppliers of texturing and rear polishing, rear passivation, laser, pastes and metallization process suppliers continue to improve technology and equipment, to increase equipment throughput and uptime, and reduce material and energy consumption.

 

At the same time, SE, MBB, and Tunnel Oxide Passivated Contact (TOPCon) are also being introduced into standard PERC cell process. By applying passivated contact technology, Jinko achieved PERC cell efficiency record with 23.95% in 2018. At present, the highest efficiency of PERC cell has been raised to more than 24%. Bifacial PERC achieves double-sided power generation with 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.

 

For N-type cell, TOPCon technology achieves back surface field passivation through tunnel oxide and doped poly-Si layer without laser opening, avoiding silicon material damage at the opening and recombination of metal contact areas. TOPCon technology is also considered to be a potential development trend for PERC cell. Meyer Burger has developed passivated contact technical solution to upgrade existing PERC line, which will increase PERC mass production efficiency to over 23%.

 

5^th PERC+ and TOPCon Forum 2019 will be held on 8 August, 2019 in Hangzhou, China. The conference will discuss global and China PV industry outlook and bifacial PERC market share, continuous optimization of PERC technology - SE, MBB, texturing and rear side polishing, back passivation, laser, paste and metallization processes, more than 24% efficiency PERC cell prospects, mono and multi PERC LID and LeTID mechanism and solutions, TOPCon technology application prospects on PERC, PERC upgrades to TOPCon process plan, etc.
