MATERIA PCE/OCC Poly Silicon Chunk Etching, Cleaning & Drying 用于硅块蚀刻、清洁与干燥的湿处理

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.

SILEX – Batch-Type IPA-Free Wet Process Equipment | 间歇式无异丙醇（IPA）的湿法处理设备

SEMI roadmap guidelines for front-end cell process in silicon solar technology.

目前和未来的批量加工应用的核心在于单晶硅的碱性制绒加工，生成的角锥形蚀刻表面具有最适宜的陷光性和接触性。

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 rapping and contacting properties. The SILEX ALTEX machine is designed to apply a new IPA-free texturing process, 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, wet-chemical texturing process for silicon wafers on the basis of commercialized additives. The application of this alkaline texturing process increase the etching bath lifetime significantly. At the same time, the texture etching can be operated in a shorter time. The resulting higher machine availability, outstanding texture performance and last but not least easier facility handling of process chemicals compared to traditional systems reduce the production costs for mono-crystalline silicon solar cells substantially.

SILEX ALTEX设备应用了新的无异丙醇变形工艺，较之传统蚀刻系统，能显著节省成本。这一制绒工艺完全不使用异丙醇（IPA）之类易燃、挥发性溶剂，主要采用市场有售的添加剂来对硅晶片进行湿法化学制绒加工。通过这种碱性制绒工艺，可显著提高腐蚀液寿命，并同时减少制绒所需的时间。与传统系统相比，机器的可靠性更高，制绒性能更出色，而且不可忽视的一点是，工艺化学品的设备操作更为简单，从而使单晶硅太阳能电池的生产成本大大缩减。

The second pillar of wet batch process applications in front-end cell production are wet cleaning processes.

SILEX – Batch-Type IPA-Free Wet Process Equipment | 间歇式无异丙醇（IPA）的湿法处理设备

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. Ozone-based 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, ozonated 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支柱在于湿法清洗。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。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，根据大家熟知半导体行业经验，臭氧化酸洗成为传统昂贵的多步RCA清洗的理想替代品。德国新格拉斯科技集团为扩散和表面钝化之前的湿法清洁提供了集成的臭氧处理方案，可集成到新设备中并为现有SILEX湿台架提供升级。

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 up to 10 lanes for high throughput production tool.

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。太阳能电池背面的电介质钝化层由AlOx 和 SiNx 堆积而成，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层，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 %据说是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。
