“…This was reasonable because the size of the test area was larger using the same light source. The light intensity around the test area would decrease the non-uniformity of solar simulator as [1], [2], [10], [14], and [28]. However, the experimental results were shown that the array detector scanning system measurements were more reliable because each measurement result in the same test-area were %uncertainty in average of 1.41% lower than that of the single detector (5.79%) significantly.…”

Solar simulator is used to analysis characteristic of the solar cells. The non-uniformity is its major performance. The traditional non-uniformity measurement calls single detector method. The paper’s objective is to design and construct an array detector scanning system and to determine the optimal scanning time to achieve the lowest uncertainty. To investigate the non-uniformity by our proposed method and the traditional method, our detector consisted of eight photodiodes mounted on an arm of a linear motion lead screw to guide the detector scaning onto the lighting area. A microcontroller applied for controling and measuring light irradiance in 64 points corresponding to IEC 60904-9 standard. The results showed that the array detector scanned at a speed of 33.33 mm/s to obtain the non-uniformity with the lowest uncertainty, less than 0.6%. Analysis results of the non-uniformity obtained from our system on the test areas of (mm×mm) 156×156, 166×166 and 200×200 compared with the single detector. It showed that the mean absolute error was 1.27. Our system provided a lower uncertainty than the traditional method. The measurement accuracy was acceptable. The advantage is for testing on different test areas within a single device. The measurement time is around 1/32 of the traditional method.

“…Single detector captures and scans light intensity at various locations on the test area [9]. It is appropriate for steady state non-uniformity [1], [2], [10], [11]. The advantages of this method are easy to measure and not complicated because it uses only one photo detector.…”
