Overview

HCPS-100 is a small illumination area solar simulator with AAA level performance. It is designed specifically for the research of advanced solar cells that require small lighting areas. It consists of a 100W xenon lamp light source, a homogenizer, and a high-performance power supply. The lighting area can be greater than or equal to 40mm; 40mm. According to ASTM, IEC, and JIS international standards, the irradiance spectrum and stability of irradiance over time are both ≤ 25%. The spatial uniformity of irradiance within a range of 400mm2 can also be better than ≤ 2%.

Product Details

feature

　　Spectral matching of irradiance is a key factor in solar simulators. In order to better evaluate the spectral performance of solar simulators, the IEC 60904-9 (2007) standard divides the solar spectrum from 400nm to 1100nm into different segments with a bandwidth of 100nm or 200nm. But with the development of efficient solar cell technology, spectral matching of irradiance in solar simulators has become increasingly necessary.

In 2020, IEC released the latest evaluation standard for solar simulators, IEC60904-9:2020This standard evaluates the irradiance spectrum of solar simulators using a wider wavelength range (300nm to 1200nm) and a narrower band. For detailed information on evaluation methods, please refer to our“Solar Simulator - Basic Knowledge and Working Principles”And the "What is AAA Solar Simulator" sectionICE needsPlease ensure that the deviation of each band is between 0.75 and 1.25, regardless of whether it is the old or new version of IEC 60904-9 standard. Both the old version of IEC 60904-9:2007 (older, easier) and the latest version of IEC 60904-9:2020 (newer, more difficult) achieved spectral matching evaluation of HCPS-100 within the range of 300nm to 1200nm≤25%Thanks to Enlitech's AM 1.5G filtering technology, the HCPS-100 solar simulator's irradiance spectrum and sustainability are far superior to other brands of solar simulators in the same class.

The wavelength range is from 400nm to 1100nm, divided into 6 bands.specificationRequire the evaluation values of each band to be within a deviation range of 0.75 to 1.25. The results showed that all band evaluations of the HCPS-100 solar simulator were A or A+.

The wavelength range is from 300nm to 1200nm, divided into six bands with a wider coverage, making it difficult to achieve good classification results. Nevertheless, the spectral matching performance of HCPS-100 is still outstanding. This proves that the key spectral performance of the HCPS-100 solar simulator is excellent, unrestricted by its compact size design.

≤2%Uniformity of spatial irradiance

The uniformity of spatial irradiance is the second indicator for the classification of solar simulators, and it is also the most difficult among all parameters. The hotspots of spatial irradiance uniformity can greatly affect the power conversion efficiency test results of solar cells and cause incorrect grading of solar cells. The HCPS-100 adopts Enlitech * equalization technology, which can convert irregular beam points into uniform spatial beam illumination areas, reducing the distribution of irradiance hotspots. The spatial irradiance uniformity of HCPS-100 solar simulator can meet IEC, ASTM, and JIS standards, which is 400mm 2inside≤ 2%.For more detailed information, please refer to our technical article:“Solar Simulator - Basic Knowledge and Working Principles“What is AAA Solar Simulator”PartialThe illumination area size of the HCPS-100 solar simulator is very suitable for many new solar cell research projects, most of which start from small effective areas such as 2mm x 2mm.

It displays the spatial distribution of equivalent solar irradiance, reaching within an area of 400 square millimeters≤2%.

≤2%Irradiance time stability

The third important parameter is the stability of irradiance over time. The time stability of the output light from the solar simulator directly affects the current voltage (IV) tracking curve of the tested solar cell. The unstable light on the tested device will affect the accuracy of the solar cell conversion efficiency value.

The HCPS-100 solar simulator adopts a high stability xenon lamp power supply system, which can maintain high time stability of xenon lamp irradiance output without the need for a light feedback control system.

The red and blue lines represent the lower and upper bounds of the A-class classification, respectively. The results indicate that HCPS-100 meets Class A requirements.

Maximum irradiation intensity ≥ 1400 W/m2(1.0 Sunlight)

With efficient optical design and components, the maximum output AM1.5G irradiance of HCPS solar simulator can exceed 1400 W/m ² (>1.0 solar). This is much higher than other compact solar simulators, which typically have less than 1.2 suns (1200 W/m ²).

According to IEC and ASTM standards, characteristic testing of photovoltaic and solar cells should be conducted under STC (Standard Test Conditions). The STC conditions are AM1.5G spectrum, 1000 W/m ² (1sun), and 25 degrees Celsius.

In general, when the output irradiance intensity of the solar simulator is less than one sun (1000 W/m ²), it is necessary to replace the lamp tube of the solar simulator. This makes it impossible to conduct characteristic testing of solar cells under STC conditions. At this time, the lamp is still emitting photons and irradiance, but cannot reach 1000 W/m ². The higher maximum output irradiance allows the HCPS-100 solar simulator to have a longer running time. This makes HCPS-100 more cost-effective than other compact solar simulators.

System Design

Adjustable output irradiance function

The HCPS-100 solar simulator can generate irradiance exceeding one solar intensity using an AM1.5G filter. The light intensity can be adjusted through the built-in mechanical aperture. By adjusting the aperture of the mechanical aperture, the irradiance can be set to AM1.5G per 1 sun (1000 W/m ²).

Users can also choose the optical plate and optical rod module to adjust the height and distance between HCPS-100 and the test plane. Changing the distance can easily change the light intensity, making HCPS-100 applicable to many research fields.

Figure 6 shows that the HCPS-100 solar simulator can be easily installed on optical rod modules and optical plates.

Manual optical shutter

The HCPS-100 solar simulator has a built-in optical shutter that can be used to turn on or off the HCPS-100 irradiance output.

Easy to install and maintain

Unlike other compact solar simulators, due to the imbalance of the system's mechanical mass center, these solar simulators must be screwed onto an optical breadboard or other board in order to be securely installed. The HCPS-100 solar simulator, due to its balanced mechanical design, can stand firmly on any plane. It also provides a screw slot for M6 screws, which can be fixed on any plane for users to conduct experiments. This greatly increases the flexibility for users to apply the HCPS-100 solar simulator to their application areas. The maintenance of HCPS-100 is also very simple. Xenon lamps are factory manufactured optical reflector types, so users do not need to adjust the position of the bulb inside the optical reflector when replacing the bulb.

4 flexible lighting directions: up, down, left, and right
Reference for irradiance calibration
A battery reference cell is a standard unit commonly used to calibrate the irradiance intensity of a solar simulator to 1 sun (1000 W/m ²). Enlitech provides various reference batteries, all of which are packaged in WPVS type. The calibration of these reference standard batteries can be traced back to NREL and SI units. Enlitech has obtained MRA certification and complies with ISO 17025:2017 calibration laboratory standards, providing users with reliable test results.
