OAI单脉冲太阳能模拟器和I-V测试系统是专为高效太阳能电池设计的。该测试系统通过提供高度优化的脉冲宽度和电压扫描速率来克服闪存测试的限制，以匹配电池的电介质响应速度。因此，该系统产生太阳能电池效率的非常精确的测量，导致更准确的分箱和增加的盈利能力。

单晶Si，多晶Si，HIT和背面接触型太阳能电池设计的进展已导致电池电容和电阻增加大于2个数量级。这导致电池的电介质响应速度的降低。大多数闪光测试仪提供极短的脉冲持续时间，并且需要快速的电压扫描速率。通过使用闪光测试仪测试太阳能电池，结果可能产生不一致的填充因子值和较低的电池效率测量。

 

高效率电池需要约75-200ms的脉冲宽度和<15V /秒的电压扫描速率的工作范围，这为闪存测试系统准确地确定这些先进电池的性能造成了重大挑战。 OAI的新型单脉冲太阳能模拟器和I-V测试系统克服了这些限制，并为高效太阳能电池提供了非常准确的测量。该测试系统适用于研发和生产，通过提供优化的长脉冲宽度和电压扫描速率以及独特的算法，解决了高效率和高电容太阳能电池独特的测量挑战。结果是I＆V曲线的准确测量以及确定太阳能电池的真实填充因子和效率的能力。

Single Long Pulse Solar Test System for High Efficiency Cells

The OAI Single Long Pulse Solar Simulator and I–V Test System is designed specifically for High Efficiency Solar Cells. This test system overcomes the limitations of flash testing by providing a highly optimized pulse width and voltage sweep rate to match the cell's dielectric response speed. As a result, the system produces extremely precise measurements of solar cell efficiency leading to more accurate binning and increased profitability.

Advances in mono-crystalline Si, multi–crystalline Si, HIT, and backside–contact type based solar cell design have led to an increase in cell capacitance and resistance by >2 orders of magnitude. This results in a decrease in the cell's dielectric response speed. Most flash testers provide extremely short pulse duration, and require fast voltage sweep rates. By testing solar cells with flash testers, the results can give inconsistent fill-factor values and lower cell efficiency measurements.

High Efficiency Cells require a pulse width in the range of ˜ 75–200ms and a working range of <15V/sec voltage sweep rates, creating a significant challenge for flash test systems to accurately determine the performance of these advanced cells. OAI's new Single Long Pulse Solar Simulator & I–V Test System overcomes these limitations and provides exceptionally accurate measurements for High Efficiency Solar Cells. Perfect for both R&D and production, this test system solves the unique measurement challenges of High Efficiency and High Capacitance Solar Cells by providing an optimized long pulse width and voltage sweep rate combined with a unique algorithm. The result is accurate measurement of the I&V curve and the ability to ascertain the true fill-factor and efficiency of a solar cell.
