晶体硅光伏电池的标准测试

为了建立太阳电池的标准测试规范流程，对影响太阳电池标准测试不确定度的各类因素进行了评价和筛选。基于太阳光模拟器、分光感度仪、IV测试仪、标准太阳电池等二级太阳电池标准测试设备与器件，开展了多项标准测试技术的研究。对电池测量过程中太阳电池模拟光源的空间不均匀性、时间不稳定性、仪器测量重复性、扫描方向导致的不确定度、电池反射率和透射率、面积测量不确定度、量子效率等各类影响因素进行了测量，给出了高效晶体硅太阳电池测量不确定度的测量流程，最终导出在现有实验室测量条件下的扩展测量不确定度为±3.94%。基于对常规太阳电池测试数据的比较，对常规电池测量方法进行了改进，将测量不确定度降低了0.19%。最后，提出了双面电池的精确测试流程和方法，为其它双面光电池的标准化测量提供了借鉴。

Standard measurement of crystal silicon solar cells

To build a standard test specification for solar cells, various kinds of affect factors on the final uncertainty of solar cell standard tests were evaluated and selected. Based on the secondary solar cell standard test equipment and devices, such as sun simulator, spectral sensitivity, IV tester and standard solar cells, several kinds of testing technologies were researched. Some effect factors in measuring processing were discussed, including the spatial uncertainty of solar cell simulator, temporal stability, measuring repeatability, the uncertainty from sweep directions, the reflection and transparence of cell, the uncertainty for area and External Quantum Efficiency (EQE). Then, the measuring procedure of a high efficiency crystalline silicon solar cell was proposed and the extension test uncertainty of 3.94% was derived under the conditions of existing laboratory measurement.Based on a comparison to conventional solar cell test data, the conventional cell testing method was improved, and the uncertainty of measurement was reduced by 0.19%. Finally, a standard testing procedure for a double-side cell was proposed, which provides a reference for other related cell measurements.
