Parameter extraction of photovoltaic cell model based on manufacture datasheets often uses parameter semi-empirical equations to obtain parameters under different conditions. These semi-empirical equations are approximate formulas and can increase model error. This paper proposes a parameter extraction method for 5-parameter single-diode model of photovoltaic cell under different irradiances and temperatures. It uses key-point data of I-V curve in manufacture datasheets to compute key-point current and voltage under different conditions by applying temperature coefficients of short circuit current and open circuit voltage. Based on the key-point data under certain conditions, the model parameters and I-V curve can be obtained by solving the proposed equation set. The proposed method was tested on high-efficiency monocrystalline silicon solar cell for parameter extraction and I-V curve computation. Experiment and simulation results demonstrate that the proposed method outperforms methods using semi-empirical equations to obtain parameters under different conditions, and the root mean square error (RMSE) values were less than 5% under all test conditions.
