Today, as photovoltaic cells move from the laboratory to GWh-sized super factories, and in an era where aerospace components need to withstand "panoramic" sunlight tests, when a calcium titanate module of several square meters or an entire drone wing is placed on the test bench... We suddenly realize that the traditional "point light source" type solar simulator has become a bottleneck restricting the efficiency of research and quality inspection.
Its light spots cannot cover the entire sample; its uniform areas, like a luxurious "island", force the test to become a cumbersome "jigsaw puzzle game"; its existence seems to remind us: true innovation should not be constrained by the size of "light".
How to obtain a vast, uniform and stable "artificial sky" that enables large-scale and integrated precise testing? Savant Optics has provided a groundbreaking solution - a large-format solar light simulator.
What is a large-format device? - A revolution in perspective from "gazing" to "overlooking"
If a conventional solar light simulator is like a precise "laser pointer", then the large-format solar light simulator produced by Sevan Optoelectronics is like an "artificial sun" suspended in the dome of the laboratory.
Spatial scale transition: We have redefined the "illuminated area". From the standard 10cm x 10cm, to 50cm x 50cm, and even to ultra-large formats of 1m x 2m or larger, the product matrix of Sevan Optoelectronics can meet the testing requirements of different scales, ranging from micro-components to building components.
Full-area uniform light curtain: The core breakthrough lies in that it no longer creates a localized "uniform light spot", but generates a continuous "uniform light curtain" with highly consistent spectrum and intensity. Under this light curtain, any position of the sample is bathed in standard daylight, completely eliminating the data discontinuities and error accumulation caused by the splicing test.
Systematic perspective: This is not merely an upgrade of the equipment, but an innovation in the testing concept. It treats the test object as an inseparable whole, allowing us to evaluate its comprehensive performance in a large area and gain insight into the subtle interrelationships between the local and the overall.
The core advantages of Sefan Optoelectronics' large-format solution: Spanning vast areas without any error
Controlling such a large light field is the ultimate test of an enterprise's optical design and system engineering capabilities. Sefan Optoelectronics, leveraging its profound accumulation, transformed the challenge into an advantage, creating the four major fortresses of the large-format simulator.
An extremely large and uniform field enables us to "see everything at a glance" from the data.
Patented optical path homogenization technology: Our unique multi-layer lens array combined with compound eye lens technology can divide and superimpose the light emitted by the source billions of times. Eventually, it "evenly spreads out" all the light intensity differences on a huge plane, achieving a spatial irradiation uniformity of over 90%.
Bid farewell to "edge effect": For large-sized samples, the performance attenuation at the edge area is an important indicator. Our simulator ensures that every point from the center to the edge meets the testing standards, making the quantitative assessment of edge performance simple and reliable for the first time.
2. Modular array light source: Stability is the foundation of its wide application scope.
"Beehive-style" redundancy design: We assemble an array of multiple high-performance sub-light source modules instead of a single large-scale light source. This not only reduces the failure risk of individual components, optimizes thermal management and power consumption, but also through an intelligent control system, enables hundreds of light-emitting units to work collaboratively as if they were "one entity", ensuring long-term irradiation stability over an extremely large area (better than ±1%).
Intelligent thermal management: To address the heat generated during high-power operation, we have designed an efficient liquid cooling/wind cooling system. This ensures that the spectral characteristics of the light source remain stable even when operating at full load for an extended period, significantly extending its lifespan.
3. Highly customized and systematized integration capabilities
Sizes are determined as needed: Sefan Optoelectronics deeply understands that each customer's sample is unique. We can tailor the irradiation area and optical path structure based on your sample size, shape, and even special layout, truly achieving "tailoring to the individual".
Building an "optical-electrical-mechanical" integrated testing platform: Our capabilities extend beyond just the light source. We can deeply integrate large-scale simulators with IV testing systems, high-precision mobile scanning frames, environmental chambers (with temperature and humidity control), etc., to create a fully automated, unmanned值守 large-scale comprehensive testing system， meeting all your needs from research and development to production in one go.
4. Excellent cost-effectiveness, reducing your one-time testing costs
Exponential improvement in efficiency: Imagine that the testing process, which previously required dozens of assemblies, can now be completed with just one exposure. This not only saves precious time but also eliminates the human and system errors introduced by multiple operations.
Reduction in single-point costs: For production line quality inspection that requires extensive testing, the unit area testing cost of a large-format system is much lower than that of multiple small devices combined. The return on investment (ROI) is immediately clear.
Application scenario: Enabling innovative practices that illuminate vast horizons
Saifan Optoelectronics' large-format solar light simulator is providing the strongest support for those "big-sized" dreams:
Next-generation photovoltaic manufacturing: Conduct comprehensive I-V, EL, and quantum efficiency measurements on large-sized perovskite/stacked solar cells and BIPV (building-integrated photovoltaics) modules, and evaluate their overall power generation capabilities and defect distributions under real light conditions.
Aerospace and Defense: Conduct full-scale thermal vacuum and irradiation combined tests on satellite solar panels, large composite material skins, unmanned aircraft wings, etc., to simulate their comprehensive performance in orbit or high-altitude environments.
Architecture and Automotive Glass: Evaluate the insulation, light transmission and power generation capabilities of large-area Low-E glass, photovoltaic glass, and skylights, providing data support for the design of green buildings and intelligent cabins.
Research on material aging and corrosion: Conduct simultaneous or sequential tests of light aging and salt spray corrosion on large coating samples and polymer plates to study their durability in complex environments.
With light as the backdrop, it carries out grand narratives.
The progress of research and industry is shifting from meticulous refinement of a single point to the overall control of complex systems and macroscopic objects. The Sefan Photovoltaic Large Area Solar Light Simulator is precisely designed for this purpose.
What it offers is not merely a greater amount of light, but also a broader perspective, a more efficient path, and more reliable global data. It enables us to stand at a higher level and examine our creations, measure the distance between us and the future.
