TheSmall Solar Simulatoris a precision laboratory device designed for the controlled simulation of solar radiation. You can use it to replicate sunlight intensity and spectrum for research and development or production testing of photovoltaic cells, materials, and modules. This simulator enables accurate performance evaluation, material aging tests, and chemical or photocatalytic reaction studies. Its compact design, adjustable irradiance, and stable output make it ideal for laboratory environments requiring reliable and repeatable solar simulation.
Applications
Photovoltaic Device Testing: Measure short-circuit current (Isc), open-circuit voltage (Voc), fill factor (FF), and photovoltaic conversion efficiency (η) for solar cells or modules.
Photocatalysis & Chemical Research: Conduct photocatalytic degradation, photochemical synthesis, and material response experiments under controlled light conditions.
Material Weathering Assessment: Simulate prolonged sunlight exposure to evaluate aging resistance of coatings, plastics, and cosmetics.
R&D of Photovoltaic Materials: Test new solar materials such as DSSC, PSC, and perovskite under standardized solar spectra.
Ground Testing for Spacecraft: Provide irradiation for solar sensors, thermal control systems, and satellite component verification under near-space conditions.
