光伏玻璃是制造太陽(yáng)能光伏電池組件必不可少的重要原材料，主要用于光伏組件的透光面板，覆蓋在光伏組件上的光伏玻璃經(jīng)過(guò)鍍膜后，可以確保有更高的光線透過(guò)率，同時(shí)經(jīng)過(guò)鋼化處理的光伏玻璃具有更高的強(qiáng)度，可以使太陽(yáng)能電池片承受更大的風(fēng)壓及較大的晝夜溫差變化。

常規(guī)的光伏電池組件蓋板使用光伏玻璃，雙玻組件的蓋板和背板都使用光伏玻璃，且背板光伏玻璃必須在特定位置打孔才能把光伏電池組件的電流導(dǎo)線引出到接線盒。

激光劃線是通過(guò)激光將整片電池分割成一定大小數(shù)量的子電池，并形成串聯(lián)結(jié)構(gòu)。激光劃線速度、效率、良率更高，相比較于機(jī)械劃線而言不會(huì)因?yàn)槿墼斐啥搪?。另外，激光劃線是非接觸式加工的方式，不會(huì)對(duì)基材造成損傷，特別是P1、P2、P3襯底的材質(zhì)、硬度、厚度等都有不同，激光劃線優(yōu)勢(shì)更加明顯。

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. UW?Laser 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.
