高精度激光划线

是钙钛矿电池量产线的核心制程

钙钛矿太阳能电池是以钙钛矿晶体为吸光材料的一种新型太阳能电池技术，可实现30%以上的光电转换效率，其兼备高效率和低成本以及对环境造成的影响较小等特点，被认为是极具潜力的高效率低成本光伏技术之一。

光伏玻璃是制造太阳能光伏电池组件必不可少的重要原材料，主要用于光伏组件的透光面板，覆盖在光伏组件上的光伏玻璃经过镀膜后，可以确保有更高的光线透过率，同时经过钢化处理的光伏玻璃具有更高的强度，可以使太阳能电池片承受更大的风压及较大的昼夜温差变化。

常规的光伏电池组件盖板使用光伏玻璃，双玻组件的盖板和背板都使用光伏玻璃，且背板光伏玻璃必须在特定位置打孔才能把光伏电池组件的电流导线引出到接线盒。

激光划线是通过激光将整片电池分割成一定大小数量的子电池，并形成串联结构。激光划线速度、效率、良率更高，相比较于机械划线而言不会因为熔渣而造成短路。另外，激光划线是非接触式加工的方式，不会对基材造成损伤，特别是P1、P2、P3衬底的材质、硬度、厚度等都有不同，激光划线优势更加明显。

当下，高精度激光划线是大幅面钙钛矿电池量产线的核心制程之一，且对于电池死区面积控制极为重要。该工序要求在形成子电池串联结构的同时，对不同膜层在不同的位置进行刻蚀，对激光工艺、系统稳定性和精度要求极高。

Illuminating the Future of Smart Manufacturing

On August 8th, the highly anticipated grand exhibition and trade event of the photovoltaic and energy storage industry, the 2023 World Solar Photovoltaic and Energy Storage Industry Expo, commenced with glory at Zone B of the China Import and Export Fair Complex in Guangzhou, China. UWLaser presented its brand-new photovoltaic glass laser scribing machine, as well as a series of intelligent manufacturing solutions for solar cells including P1,P2,P3,glass perforation, TOPCON laser film removal, TOPCON laser SE, and TOPCON laser oxidation. This dazzling display heralds a fresh start and a new direction!

In the new era of energy transition, the significance and economic viability of the photovoltaic and energy storage industry in the realm of new energy consumption and applications are further emphasized. This industry has become the hottest arena for future energy competition.

Perovskite solar cells are a novel type of solar cell technology that utilizes perovskite crystals as the absorbing material. They can achieve an efficiency of over 30% in photovoltaic conversion. These cells combine high efficiency, low cost, and minimal environmental impact, making them one of the most promising high-efficiency, low-cost photovoltaic technologies.

Photovoltaic glass is an essential raw material for manufacturing solar photovoltaic cell modules. It is primarily used for the transparent panel of photovoltaic modules. When coated and treated, photovoltaic glass on the modules ensures higher light transmittance. Additionally, tempered photovoltaic glass possesses greater strength, allowing solar cells to withstand higher wind pressures and larger day-night temperature variations.

Conventional photovoltaic cell modules utilize photovoltaic glass for cover plates, and both cover and back plates of bifacial modules are made from photovoltaic glass. Perforations must be made in specific positions on the back plate's photovoltaic glass to route the current-carrying wires of the photovoltaic cell module to the junction box.

Laser scribing is a process that involves using lasers to divide the entire solar cell into a specific number of smaller cells, forming a serial connection structure. Laser scribing offers higher speed, efficiency, and yield compared to mechanical scribing. Unlike mechanical methods, laser scribing doesn't result in short circuits due to molten residues. Additionally, laser scribing is a non-contact processing method, preventing damage to the substrate. This advantage is particularly evident for various substrate materials, hardness, and thickness, especially for P1, P2, and P3 substrates.

Currently, high-precision laser scribing plays a pivotal role in the production process of large-area perovskite solar cells and is crucial for controlling the dead zone area of the cells. This process requires the formation of a serial connection structure for the sub-cells while simultaneously etching different layers at various positions. It places extremely high demands on laser processes, system stability, and accuracy.

Key Exhibit: Photovoltaic Glass Laser Scribing Machine

UW The newly launched photovoltaic glass laser scribing machine further simplifies the process, enabling fast, precise, and consistent laser perforation. It eliminates issues such as microcracks and debris detachment, leading to increased production output and reduced defect rates. This technology eliminates the need for additional process steps and chemicals, and it boasts high precision, efficiency, and non-contact capabilities. This contributes to the high-efficiency, high-quality, and low-cost production and processing of solar panels.
