Reference Cells 标准太阳能电池
在太阳能电池分析测试过程中，通常采用标准太阳能电池来校准光源的绝对光照强度，从而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。
尤其是测试太阳能电池I—V特性时，通常采用标准太阳能电池对太阳模拟器的光照强度进行标定。
标准太阳能电池通常由封装外壳、太阳能电池、温度传感器和保护窗口等组成。其中，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用户自己选择的，同时还可以提供对标准太阳能电池的校准数据。

Reference Cells 标准太阳电池
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 modules 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.
We provide reference cells with calibration data.
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
Other options are available; please contact us to discuss your requirements.
