㈠ 锂电池充电管理IC中3种reference电压都具体是干什么用的
This photovoltaic reference cell is a radiometer used for measuring illumination levels when assessing the performance of photovoltaic devices. By quantifying the amount of light reaching a test device, it enables the light-to-electricity conversion performance of solar cells and moles to be measured and compared.
Reference cells are most commonly used to set the intensity of a light source to a particular test condition (e.g. one-sun) for I-V measurements.
Reference cells include a rugged enclosure, solar cell, temperature sensor, and protective window. Cell type, temperature sensor, and window material can be selected to meet your requirements.
CrownTech, Inc. provides reference cells with calibration data from the National Renewable Energy Laboratory.
Features of Most Common Configuration
• May be used outside (not designed for continuous outdoor use) or with solar simulators
• 2-cm by 2-cm square silicon solar cell
• Close thermal contact between solar cell and enclosure
• Temperature sensor
• 4-wire contact to the solar cell
• BK7 glass window
• Broad-spectrum, low-reflectivity coating behind window and surrounding solar cell
• Mounting hole pattern (62 mm X 62 mm) compatible with WPVS reference cell design
Options
• GaAs solar cell (instead of silicon) for testing GaAs and CdTe devices
• Customer-provided solar cell
• Quartz window or colorglass filter for customizing spectral response to resemble that of a particular test material such as amorphous silicon (instead of BK7 glass)
• RTD temperature sensor or alternative thermocouple type
• Cable termination using your preferred connector
• Different size solar cell or aperture placed over solar cell
Reference Cells 标准太阳能电池
在光电器件分析测试过程中,通常采用标准太阳能电池测试光源光照强度,有了光照强度,就可以测量计算出被测太阳能电池的光电转换效率,进而进行分析对比。
在太阳能电池电流电压特性测试中,通常采用标准太阳能电池对光源光密度进行标定。
标准太阳能电池通常包括封装外壳、太阳能电池、温度传感器和保护窗口。太阳能电池类型、温度传感器类型以及保护窗口的材料都是可以选择的,同时还可以提供美国再生能源实验室对标准太阳能电池的校准数据。
