In the field of solar energy research and product development, solar simulators play a pivotal role. In this article, we will explore a comparison between the Class AAA single xenon lamp solar simulator and the LED simulator. Although the LED simulator possesses spectral adjustment characteristics, its adjustment process is quite complicated and requires a high level of expertise. Moreover, changes in the spectrum, impacts on uniformity, and differences in the perception of lifespan and light intensity may all affect its performance. In contrast, the single light source spectral adjustable solar simulator from Enlitech requires no complex adjustments and can more accurately simulate the spectral distribution of natural sunlight, providing more precise test results. Especially for the cutting-edge perovskite layer solar cells, precise measurement is a crucial step to ensure technological progress and innovation. Therefore, choosing a suitable solar simulator is very important. In the following content, we will specifically discuss the advantages of Enlitech’s single light source spectral adjustable solar simulator and its scope of application.
While LED multi-source simulators have the characteristic of “full-spectrum” spectrum adjustment, in practical applications, their adjustment process is quite complex and requires a high level of professionalism. For instance:
- The aging speed of different color LEDs varies, necessitating an additional illuminance spectrometer to ensure spectral consistency.
- The temperature coefficients of different color LED chips are different. After prolonged use, changes in the central wavelength and intensity will cause fluctuations in the spectrum mismatch factor, requiring regular checks.
- The aging speed of each colored light and its effect on uniformity.
- Adjusting the intensity of each colored light changes the spectral distribution on the irradiation area.
- There is a discrepancy in the understanding of a 10,000-hour lifespan and 1 sun light intensity.
- Considering the time cost of adjusting the spectrum and reducing the mismatch factor, is the “cost” of using an LED simulator really lower?
For laboratories with professional calibration and uncertainty testing capabilities, they may be able to effectively use the “ideal and perfect LED solar simulator” to test various types of multi-junction solar cells because they have a deep understanding of how to accurately measure the spectrum and the iterative calculation of the mismatch factor of the entire IEC specification, and have relevant tools for measuring solar simulators.

However, for most scientific research laboratories, their expertise lies more in device physics, chemical synthesis, or materials science, and they are less familiar with optics and spectroscopy, and most lack the tools to test simulator performance.
Therefore, how to accurately measure Perovskite-Silicon Tandem Solar Cells and enable the majority of researchers and research students in scientific laboratories to quickly and automatically adjust to the best test conditions is the main goal of Enlitech’s development of a single-source spectrum-adjustable solar simulator.Compared to the complicated adjustment process and professional requirements of LED simulators, Enlitech’s products are more in line with market needs and can provide more accurate test results.
When it comes to solar technology, especially for the cutting-edge perovskite tandem solar cells, precise measurement is not only a challenge but also a crucial step to ensure technological progress and innovation. In this field, choosing the right solar simulator is of paramount importance, and the PST solar simulator, with its unique advantages, is undoubtedly the best choice for such precise measurements.

Is the cost of setting up a single xenon lamp spectrum adjustable simulator higher than an LED simulator?
The answer can be approached from the following three aspects:
- For an LED solar simulator, if it is to cover the full spectrum from 300nm to 1500nm, with high spectral conformance and uniformity, the initial setup cost of such an LED solar simulator will not be cheaper than a single xenon lamp spectrum adjustable solar simulator!
- The initial setup cost of a single xenon lamp spectrum adjustable simulator may be higher than some low-end LED simulators. This is because single xenon lamp technology often involves more complex optical systems and high-precision spectral control technologies. However, considering long-term usage costs, maintenance convenience, measurement accuracy, and efficiency of the measurement process, single xenon lamp simulators may offer greater economic benefits.
- Although low-end LED simulators have lower initial costs, they may require more frequent maintenance and calibration, especially considering the spectral changes that may be caused by the aging of LED components over time. In addition, the adjustment process of LED simulators requires complex and professional knowledge and equipment, such as a full-spectrum spectrometer (300-1700nm), and for good heat dissipation, additional cooling devices such as independent water-cooling equipment are needed, all of which increase the cost of operation and maintenance.
In conclusion, although the initial investment of a single xenon lamp spectrum adjustable simulator is not cheaper than low-end LED solar simulators, in the long run, due to its stability and low maintenance requirements, the actual total cost of ownership may be more competitive. When assessing setup costs, it should be viewed from a comprehensive perspective, including measurement accuracy, operation convenience, maintenance needs, and the impact of potential measurement errors on the research or production process.
