Class AAA Small Area Solar Simulator
HCPS-100 is a small illumination area type solar simulator with class AAA performances. HCPS-100 is designed for many advancing solar cell researches which needs small illumination area, like perovskite solar cells.
HCPS-100 is composed with a 100 W Xe lamp light source with the light homogenizer and the high-performance power supply. With advanced optical optimization, HCPS-100 has very high performance with compact system size. The illumination area can be larger than ≥ 40 mm x 40 mm. The irradiance spectrum and irradiance stability with time are class A according to ASTM, IEC, and JIS several different international standards evaluations.

Class A irradiance spectral match
Irradiance spectrum match is one of the key factors of solar simulators. To better evaluate the spectrum performance of a solar simulator, the IEC 60904-9 (2007) standard divided the solar spectrum into different segments with 100nm or 200nm bandwidth from 400nm to 1100 nm. However, with the development of high-efficiency solar cell technologies, the irradiance spectral match of the solar simulator is becoming necessary.
On 2020, IEC released latest solar simulator evaluation standard IEC 60904-9:2020 which evaluate the irradiance spectrum of the solar simulator with broader wavelength range (300nm to 1200nm) and narrower band segments. The details of the evaluation method, please see our “Solar Simulator- Basic Knowledge and Working Principles” and the section “What is AAA solar simulator”. The Class A spectral match requires the deviation of each wavelength bands is within 0.75 to 1.25 both for the old and latest IEC 60904-9 standards. The spectral match evaluations of HCPS-100 by old IEC 60904-9:2007 (Old, easier) or latest IEC 60904-9:2020 (Latest, much difficult) are both reached Class A from 300 nm to 1200 nm. It is contributed by Enlitech’s advanced AM 1.5G filter technology which makes the irradiance spectrum and sustainability of HCPS-100 solar simulator be much better other brand solar simulators in the same level size.

Figure 2. The spectral match evaluation of HCPS-100 solar simulator with the old IEC 60904-9:2007.
The wavelength range is from 400 nm to 1100 nm and divided into 6 bands. The class A classification requires the evaluation values at each wavelength band are all within 0.75 to 1.25 deviation. The results show that all of band evaluation are A or A+ for HCPS-100 solar simulator.
Figure 3 The spectral match evaluation of HCPS-100 solar simulator with the latest IEC 60904-9:2020.
The wavelength range is from 300 nm to 1200 nm and divided into 6 bands. It covers much more wavelength range and make it be more difficult to get good classification. Evan that, HCPS-100 still has outstanding spectral match performance which is much better than class A level. It proofs that the vital spectral performance of HCPS-100 solar simulator is extra ordinary great not constrained by it’s compact size design.
Class A spatial irradiance uniformity
Figure 4 Class A spatial Uniformity of HCPS-100 solar simulator.
It shows the one-sun equivalent irradiance spatial distribution achieving class A (<2%) within 400 mm2 area.
Class A irradiance temporal stability
The third important parameter is the irradiance temporal stability with time. The temporal stability of the solar simulator output illumination directly affects the current-voltage IV tracing curve of solar cell under testing. The un-stable light illumination on the device under test will cause the accuracy of the conversion efficiency value of the solar cell.
The HCPS-100 solar simulator adapts high-stability Xe lamp power supply system, which can keep Xe lamp irradiance output with high temporal stability without needing optical feedback control system.

The red and blue lines show lower and upper limit boundary of Class A classification. The result shows that HCPS-100 achieves class A requirement.
Max irradiance intensity ≥ 1400 W/m2 (1.4 suns)
According to IEC and ASTM standard, the characterization testing of PV and solar cells should be proceeded at STC (Standard Testing Conditions) conditions. The STC conditions are AM1.5G spectrum, 1000 W/m2 (1sun), and 25 degree C.
In general, the time of replacing the lamp of the solar simulator is happened in the case that the output irradiance intensity of the solar simulator is less than one sun (1000 W/m2). It makes the characterizing experiment of the solar cell can not be proceeded under STC conditions. At this moment, the lamp is still emitting photons and irradiance, but cannot be 1000 W/m2. The higher maximum output irradiance makes HCPS-100 solar simulator has more operating time period. It makes HCPS-100 has more Cost-Performance value than other compact size solar simulator.
