Solar simulator
Compact, LED Solar Simulators for Small Area PV
Description:
A compact LED‑based solar simulator designed for small‑area photovoltaic (PV) device characterization provides a reliable and cost‑effective alternative to traditional xenon‑lamp systems. The simulator uses a carefully calibrated array of high‑power LEDs to generate a steady‑state artificial solar spectrum with excellent spectral match, spatial uniformity, and temporal stability.
Designed in accordance with IEC 60904‑9:2020 international standards, this type of solar simulator delivers Class AAA performance over a small illuminated area, making it well suited for laboratory research on thin‑film, perovskite, organic, and emerging photovoltaic technologies. Its small footprint, long operational lifetime, and minimal maintenance requirements make it ideal for high‑density research laboratories and educational environments.
