METHOD FOR DETERMINING AN EQUIVALENT CIRCUIT FOR A SOLAR CELL

摘要

The invention relates to a method for calculating the equivalent circuit of a solar cell. According to the method, a pulse-like radiation effect is directed onto the solar cell and the properties of the solar cell are measured by measuring the decreasing portion of the pulse. According to the invention, the time-dependence of the radiation signal is measured and the measurement of the voltage and radiation signals is continued until the intensity of the radiation has at least halved since the moment of starting the measurement.
