“…This prototype satisfies the highest classifications (better than AAA from 400 to 750 nm) with an illuminated area of 18 cm × 18 cm with the maximum irradiance of about 2,435 W/m 2 Novickovas. [1] reported on an efficient design of a light-emitting diode (LED)-based AAA class solar simulator, employing only 19 high-power emitters for a usable illuminated area of at least 5 cm in diameter with 1 sun irradiance. The number of LEDs used in this design was very low and was able to include several wavelengths of the LED groups (400-950 n.m.) and taking advantage of wide emission angle for others.…”

“…The disadvantage of the conventional lamp is short life time (~1,000 hours), complex optical device is needed, high power consumption, low luminous efficiency, and high maintenance cost. [1] On the other hand, LEDs have more specific advantage, such as high luminous efficiency, low operating voltage, low power consumption, long life time (~5,000 to 10,000 hours) and absence of complex optical devices. Moreover, the LEDs have specific light spectral, and is easier to control light intensity.…”

Abstract-This article presents the optical design of a six-spectral LED-based solar simulator. The study focuses on the measurement methods of spectral match, the non-uniformity and the temporal instability on the test plane. The proposed six-spectral LED solar simulator has an illuminated area of 900 cm 2 and can characterize medium size photovoltaic devices under variable irradiance. The spectral range covered is between 400 nm and 1100 nm which offer the capability of characterizing silicon PV technologies. The evaluation method is in accordance with IEC 60904-9. The Solar Power meter was used to measure the irradiance and a Compact Array Spectrometer and Fiber optic spectrometer were applied for the spectral match test. The irradiance is controlled via LabVIEW which can adjust the power to drive all LEDs in the constant current mode. The irradiance of 1000 W/m 2 was applied during testing. The results found that the spectral match classification is of class B. The non-uniformity of irradiance is of A-class across the illuminated area. The temporal instability of irradiance is capable of reaching class A. This idea is perfectly appropriate for the application of the testing of I-V characteristic of the silicon solar cell. For future work, the author has to improve the spectral match to reach an A Class.

A modular array of light emitting diodes of six different wavelengths is modelled and experimentally tested to provide Class AAA solar simulator illumination over an area of 20 cm2. The module demonstrates uniform distribution of light flux density across the sample test plane region, achieving Class A AM 1.5 G irradiance (100 mW/cm2) across the 400 to 1100‐nm wavelength range. The new system has a spectral match of 99.5%, a spatial non‐uniformity of 2.0%, and a temporal instability of <0.2%. The performance of the design (which will allow for large area simulators to be cheaply assembled from multiple modules) is then critically assessed in terms of the existing solar simulator standards and benchmarked against a conventional simulator.
