 2019钙钛矿和叠层电池与组件论坛

Perovskite and Tandem Cell and Module Forum 2019

 

——30%以上效率太阳电池的低成本量产之路

——30% Efficiency Solar Cell Low-cost Mass Production Road

 

会议背景

 

钙钛矿电池是极具潜力的下一代光伏发电技术,并且正在快速走向市场。20187月,纤纳光电钙钛矿组件转换效率提升至17.9%,同年12月,牛津光伏钙钛矿/硅基叠层电池实现了28%的光电转化效率。20192月,协鑫纳米已建成10兆瓦级别大面积钙钛矿组件中试生产线,并已开始100兆瓦量产生产线的建设工作,计划于2020年实现钙钛矿光伏组件的商业化生产。

 

钙钛矿最初是指含钙、钛和氧的矿物,于1839年首次被发现。此后,钙钛矿指代一大类具有与此类矿物相同晶体结构的化合物。其化学成分简写为ABX3,其中A通常代表有机阳离子,B代表金属离子(如Pb2+Sn2+),X代表卤素阴离子(如Cl-Br-)。

 

与晶硅太阳电池需要高纯硅相比,钙钛矿电池只需材料的纯度达到90%,而且采用的低温工艺可以降低能耗,单位面积钙钛矿组件消耗的钙钛矿材料也远低于晶硅组件。因此钙钛矿电池及组件具有极大的成本降低潜力。公开信息显示,当钙钛矿组件产能达到1GW以上时,其成本有望降低到0.7/W

 

随着技术走向成熟,晶硅电池正在趋于其理论效率极限,进一步提升至27%以上的电池效率成本高昂。而钙钛矿电池与晶硅电池组成叠层电池,可以实现30%以上的光电转换效率。采用晶体硅作为底电池和钙钛矿作为顶电池的叠层电池是一项在技术和经济上均可行的选项,而且双结叠层电池技术与双面发电技术相容。

 

钙钛矿电池面临的挑战主要是稳定性和规模化制造,以及相关测试标准和测试技术尚未完善。产业链上的企业正在努力行动,以期尽快完善钙钛矿电池和组件技术。贺利氏公布其正在开发一系列产品,如低温银浆、PEDOT:PSS和导电胶,助力钙钛矿叠层电池成为新一代太阳能电池技术。

 

2019钙钛矿和叠层电池与组件论坛将于1212日召开。会议将探讨全球与中国光伏行业展望与钙钛矿技术前景大面积钙钛矿电池与组件制造工艺——涂布工艺、真空工艺、激光工艺与金属化工艺,钙钛矿电池测试标准、测试技术与长期稳定性研究,钙钛矿电池与组件成本下降潜力和投资回报、钙钛矿叠层电池组件结构设计方案与效率极限分析

Background

 

Perovskite solar cell is a promising next-generation photovoltaic technology and is rapidly entering the market. In July 2018, Microquanta’s perovskite module conversion efficiency was increased to 17.9%. In Dec. 2018, Oxford PV’s perovskite/silicon-based tandem cell achieved a conversion efficiency of 28%. In Feb. 2019, GCL Nano has built a pilot production line for 10MW large-scale perovskite modules, and has begun construction of a production line of 100MW. It is planned to commercialize perovskite modules by 2020.

 

Perovskite originally referred to minerals containing calcium, titanium and oxygen, was first discovered in 1839. Hereinafter, perovskites refer to a large class of compounds having the same crystal structure. Its chemical composition is abbreviated as ABX3, where A usually represents an organic cation, B represents a metal ion (such as Pb2+ or Sn2+), and X represents a halogen anion (such as Cl- or Br-).

 

Compared with crystalline silicon solar cells that require high-purity silicon, perovskite solar cells require only 90% purity of the material, the low-temperature process can reduce energy consumption, and the perovskite material consumed per unit area module is also much lower than crystalline silicon module. Therefore, perovskite solar cells and modules have great potential for cost reduction. According to public information, when the capacity of perovskite modules reaches more than 1GW, the cost is expected to be reduced to RMB 0.7/W.

 

As technology matures, crystalline silicon cells are moving toward their theoretical efficiency limits, and the efficiency that is further increased to more than 27% is costly. Perovskite/silicon-based tandem cell can achieve conversion efficiency of 30% or more. A tandem cell using crystalline silicon as the bottom cell and perovskite as the top cell is a technically and economically viable option, and tandem cell technology is compatible with bifacial power generation technology.

 

The challenges of perovskite solar cells are mainly stability and large-scale manufacturing, and related test standards and test techniques have not been perfected. Companies in the industrial chain are working hard to improve the perovskite cell and module technology as soon as possible. Heraeus announced that it is developing a range of products, such as low-temperature silver paste, PEDOT:PSS and conductive adhesive, to help the perovskite/Si tandem cell become a new generation solar cell technology.

 

Perovskite and Tandem Cell and Module Forum 2019 will be held on December 12 in China. The conference will discuss global and China’s PV industry outlook and perovskite technology prospects, large-area perovskite solar cell and module manufacturing processes - coating process, vacuum process, laser process and metallization process, perovskite solar cell test standards, test technology and long-term stability studies, perovskite solar cell and module cost reduction potential and return on investment, perovskite tandem cell & module structural design and efficiency limit analysis.
