Title:
ESTIMATING METHOD FOR CURRENT-VOLTAGE CHARACTERISTICS OF PHOTOELECTRIC CONVERSION ELEMENT, PROGRAM FOR CAUSING COMPUTER TO EXECUTE SAID ESTIMATION METHOD, RECORDING MEDIUM IN WHICH SAID PROGRAM IS RECORDED, AND CHARACTERISTICS ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/168165
Kind Code:
A1
Abstract:
Provided is a characteristics estimation device with which it is possible to easily estimate the current-voltage characteristics of a photoelectric conversion element. The characteristics estimation device 10 is provided with a measurement control unit 2 and a measurement unit 4. A characteristics estimation unit 20 of the measurement control unit 2 derives at least the series resistance of a solar cell 6 from first current-voltage characteristics measured at illuminance G1 and temperature T1 by the measurement unit 4. The characteristics estimation unit 20 estimates a data point comprising the current value and the voltage value of the solar cell 6 at illuminance G2 different from illuminance G1, and temperature T1, using the serial resistance of the solar cell 6 and current values and voltage values in the first current-voltage characteristics, and estimates second current-voltage characteristics of the solar cell 6.
