SINGULUS TECHNOLOGIES developed a new machine concept with the product name MATERIA PCE/OCC for the cleaning of Si chunks, Si-Off-Cuts and ingot saw off cuts for the manufacturing of crystalline solar cells. The first MATERIA cleaning machine was delivered to a renowned US customer. The system was successfully installed at the customer’s site in the 1st quarter 2012. In the MATERIA, silicon is cleared of interfering particles, organic and metallic contaminations. With state-of-the-art technology, the fully automated and intelligent carrier management, which is operating in the absence of manual labor, achieves a maximum throughput with reductions of operators. With very good process results, the efficient process steps and the economical use of water and chemical substances as well as the low energy consumption reduce the cost of operation compared with the traditionally available machines.

The core of the current and future batch process applications is the alkaline texturing process of mono-crystalline silicon, generating pyramidaletched surfaces with optimal light trapping, passivation and contacting properties. The SILEX II ALTEX machine is designed to apply IPA-free texturing processes, offering substantial cost advantages compared to traditional etching systems. This texturing process completely refrains from using flammable, volatile solvents such as Isopropanol (IPA) and enables a stable, wetchemical texturing process for silicon wafers. Based on commercially available chemicals the process is adjustable to the individual requirements of standard and advanced cell technology.

The second pillar of wet batch process applications in front-end cell production are wet cleaning processes. Advanced cleaning steps are going to become an indispensable part of existing present and future cell lines as a key for further improvement of cell performance and cost reduction. Ozonebased cleaning operations, applied on SILEX wet bench, combine efficient organic and metal removal with appropriate surface conditioning. Due to low chemical cost and consumption, simple process control, and high metal removal efficiency, ozonized acidic cleaning bathes are the perfect substitute for traditional, expensive multi-step RCA cleanings, known from semiconductor industry.

前端电池生产中湿法批量加工应用的第二大核心在 于湿法清洗。在目前和未来电池生产线上,先进的 清洁程序将成为不可或缺的一环,成为进一步提高 电池性能和降低成本的关键所在。基于臭氧的清洁 操作在SILEX湿台架上进行,在进行表面修整的同 时能有效地去除有机和金属杂质。由于化学品的成 本和消耗量较低,工艺控制简单且金属去除效率较 高,根据半导体行业经验,臭氧化酸洗是传统工艺 中昂贵的多步RCA清洗的理想替代品。

LINEA II – Single Side Polish Etch | 单面抛光蚀刻

LINEA II Single Side Polish Etch 单面抛光蚀刻 SINGULUS TECHNOLOGIES cooperates with cell manufacturers worldwide and develops processes which improve the efficiency of solar cells and at the same time reduce production costs. Evolutionary improvement in cell concepts like PERC or PERT, n-type material, IBC cell or heterojunction cells will drive the future of crystalline solar cells. Standard silicon solar cells have a textured front and rear side. In order to optimize the light trapping within the cell and the conditions for a good rear side passivation with local contacts, a planar rear surface is most suitable. The differently structured front and rear surfaces of the wafer make the implementation of a single side etching process step essential. For the market of silicon solar cells, SINGULUS presents a new production solution for rear side passivated silicon solar cells (e.g. PERC – Passivated Emitter and Rear Cell). This solution was developed especially for the upgrade of existing cell production lines. For the upgrade of a production line, three additional production steps, which SINGULUS offers solutions for, are required. Before coating the rear side is smoothed with a wet-chemical polish in a LINEA II Single Side Polish Etch machine. The dielectric passivation layer is emitted in the ICP-PECVD machine SINGULAR. For the rear side contacts through a laser process, SINGULUS is closely cooperating with a partner.With the integration of these additional production steps into existing manufacturing lines PERC cells with levels of efficiency of up to 20 % can be achieved. SINGULUS TECHNOLOGIES offers for R&D single lanes and machine versions up to 10 lanes for high throughput.

PERCEUS – Production Package for PERC Solar Cells | PERC太阳能电池综合生产设备

Etch. The dielectric passivation layer on the rear of the solar cell, consisting of a layer stack of AlOx and SiNx, is coated by the ICP-PECVD production tool SINGULAR XP. For the final step, the rear contact formation done by Laser Contact Opening (LCO), SINGULUS TECHNOLOGIES is cooperating closely with partners. With the integration of these additional production steps into existing production lines, PERC cells with efficiencies of up to 20 % can be made. In March 2012, the Institute for Solar Energy Research Hameln (ISFH) increased the conversion efficiency of screen-printed silicon solar cells in cooperation with SINGULUS from today’s industry typical 18.5 % to a record value of 20.1 %. This was also confirmed by an independent measurement from the photovoltaics calibration laboratory of the Fraunhofer ISE (CalLab). An improved cell rear side with an ICP-AIOx/SiNy double layer (ICP: “Inductively Coupled Plasma”) enables this progress without “selective emitter” technology. 20.1 % is one of the highest efficiencies worldwide reported for industrial type silicon solar cells with screen-printed metallization.

德国新格拉斯科技集团为生产升级方案PERCEUS 而推出了附加的加工工序。在湿法化学加工工序 中,通过LINEA II 单面抛光蚀刻设备来抛光电池的 背面。太阳能电池背面由AlOx 和 SiNx组成的的电 介质钝化层通过ICP-PECVD生产工具SINGULAR XP 进行镀膜。在最后一步,通过激光开槽形成背面接 触,集团与合作伙伴进行了密切合作。通过将这些 附加的生产工序集成到现有生产线,PERC电池的 效能可提高到20 %。 2012年3月,哈默尔恩太阳能研究机构(ISFH)通 过与SINGULUS合作,将丝网印刷硅太阳能电池的 转换效率从行业内通常的18.5 % 提高到创纪录的 20.1 %。Fraunhofer ISE (CalLab)的光伏校准实验 室通过独立检测对这一点也进行了证实。改进后的 电池带有ICP-AIOx/SiNy双重镀层(ICP:“电感耦 合等离子体”),无需“选择性发射极”就能实现 这一转换过程。20.1 %是已报道的全球范围内采 用丝网印花金属化的工业类硅太阳能电池的最高转 化率。

SOLARE Turn-key Production System for Crystalline Cells 晶硅电池的交钥匙生产系统

SOLARE Turn-key Production Systems for Standard Cells as well as new PERC Cells

SOLARE 标准电池及 新PERC 电池的交钥匙生产系统

SINGULUS TECHNOLOGIES cooperates with cell manufacturers worldwide and develops processes which improve the efficiency of solar cells and at the same time reduce production costs. Evolutionary improvement in cell concepts like PERC or PERT, n-type material, IBCcell or heterojunction cells will drive the future of crystalline solar cells. A standard SOLARE system consists typically of the following production steps:

德国新格拉斯科技集团携手世界各地的电池制造商 共同改进生产工艺,在提高太阳能电池的效率的同 时降低生产成本。电池概念方面的进展,如PERC/ PERT,N型材料、全背面接触式电池或异质结太 阳电池将推动晶硅太阳能电池的未来。一个标准的 SOLARE系统一般包括以下生产步骤:

01 Wafer Stack Splitting, Loading/Inspection 02 Saw Damage Etch (SDE) and Texturing 03 Junction Formation 04 Phosphorus Silicate Glass Removal/ Edge Isolation 05 SINGULAR – ICP-PECVD Production Platform for Passivation and Anti-reflection Coatings 6/7 Printing/Firing 08 Testing/Sorting
