Patent ID: 8598903

Claim:
A testing device for testing a photoelectric conversion die, the testing device comprising: a laser source configured to emit a laser beam irradiating on the photoelectric conversion die; a current testing device configured to measure current values output by the photoelectric conversion die; and a processor in communication with the current testing device and the laser source, the processor comprising: a user interface configured for receiving user inputs, thus to determine control parameters of the laser source corresponding to the user inputs; a control unit configured for receiving the control parameters and controlling the laser source to emit the laser beam according to the control parameters, the laser beam having an optical output power value P, the control unit also controlling the current testing device to measure a current value I output by the photoelectric conversion die after the laser beam irradiating on the photoelectric conversion die; a calculation unit configured for calculating a photoelectric conversion efficiency F according to the formula: F=P/I; and a data generation unit configured for processing the photoelectric conversion efficiency F which indicates the electro-optical property of the photoelectric conversion die.
