Apparatus and Method for Measurement of Radiation Intensity for Testing Reliability of Solar Cell, and Method for Testing Reliability of Solar Cell

A method for measurement of radiation intensity for testing reliability of a solar cell, comprising:

• sensing a temperature of one of at least two solar cells which receives light in a reliability testing apparatus, with the other solar cell covered not to receive light;
• exposing the other solar cell to receive light;
• controlling a temperature of the other solar cell exposed to receive light according to the sensed temperature of the one solar cell;
• and
• measuring intensity of radiation applied to the other solar cell.

A method for testing reliability of a solar cell, comprising:

• measuring intensity of radiation of a solar cell by a method for measurement of radiation intensity for testing reliability of the solar cell;
• and
• testing a degree of deterioration of the solar cell according to the measured intensity of radiation,
