㈠ 鋰電池充電管理IC中3種reference電壓都具體是干什麼用的
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 標准太陽能電池
在光電器件分析測試過程中，通常採用標准太陽能電池測試光源光照強度，有了光照強度，就可以測量計算出被測太陽能電池的光電轉換效率，進而進行分析對比。
在太陽能電池電流電壓特性測試中，通常採用標准太陽能電池對光源光密度進行標定。
標准太陽能電池通常包括封裝外殼、太陽能電池、溫度感測器和保護窗口。太陽能電池類型、溫度感測器類型以及保護窗口的材料都是可以選擇的，同時還可以提供美國再生能源實驗室對標准太陽能電池的校準數據。
