It defines terminology and establishes standard tests, environmental conditions, procedures, and systematic methods for verifying the capability of a photovoltaic solar cell device to operate in the environment of space.
This standard is intended to be used to establish the minimum level of testing required to demonstrate that a solar cell type will operate in a predictable and understood manner. Success and failure criteria are defined for each qualification test.
This standard establishes qualification, characterization, and quality requirements for all solar cells intended for operations in space.
The measured values for voltage, current and temperature are recorded by separate and externally triggered calibrated multimeters. Both n- and p-type solar cells with edge lengths between 20 and 175mm and short-circuit currents of up to 15A are measured. Figure 2. CalTeC’s I–V curve measurement facility.
