产品说明

分享到:
电致发光,又称场致发光,英文名为Electroluminescence,简称EL。电致发光依靠从扩散区注入的大量非平衡载流子不断地复合发光,放出光子;再利用CCD相机捕捉到这些光子,通过计算机目前,电致发光成像技术已被很多太阳能电池和组件厂家使用,用于检测产品的潜在缺陷,控制产品质量。而便携式EL设备由于其方便携带,可用于户外EL测试,对光伏系统进行检测和诊断,不断受到光伏业内的人士的关注。

System's Benefits
• No need to demount the Solar Module (save time/cost)
• Direct outdoor Measurements possible
• Excellent Sensitivity and Image Quality
• Quick Measurements (~2sec for c-Si Solar Modules)
• No dark Box or Cover needed
• Mobile Solution, no Transport Vehicles needed
• Battery based System allows independent Operation
Successfully tested on various Solar Cell/ Module Types
• Monocrystalline Silicon (mono-Si)
• Polycrystalline Silicon (poly-Si)
• Amorphous Silicon (a-Si)

Battery-powered LumiSolarOutdoor System
The battery based version of the LumiSolarOutdoor system does not need any external power source. A powerful battery generates the electricity for both, camera and the solar
module being measured. It is possible to apply up to 100V and 7.5A to the module.
