Steady-State
At neonsee, we offer customized solar simulation solutions meeting and even exceeding Class A requirements. Our unique system architecture enables the continuous adjustment of light intensity over the entire intensity range (0-120%) while remaining compliant with Class A requirements with regard to spectrum, homogeneity and temporal stability of irradiance (IEC 60904-9, ASTM E 927).
neonsee sun simulation technology is based on the steady-state principle. This allows for testing of cell materials with longer response times than crystalline p-n silicon material and is therefore successfully utilized in multi-junction photovoltaic cell testing, such as thermal balance testing.
