## Abstract

The invention discloses a photovoltaic cell output characteristic modeling method in the technical field of photovoltaic power generation. According to the technical scheme, the method comprises the following the steps of: establishing a single exponential parameter initial model which comprehensively reflects photovoltaic cell output characteristics; enabling the single exponential parameter initial model to be explicit by utilizing a Lambert W function so as to obtain a photovoltaic cell explicit model; calculating a to-be-calculated parameter value in the initial model under a standard working condition by utilizing data provided by manufacturers and a parameter calculating algorithm; and calculating a parameter value under a given working condition by utilizing the parameter value under the standard working condition and a parameter transformation algorithm; and substituting the calculated parameter value into the photovoltaic cell explicit model, thereby obtaining the photovoltaic cell model which comprehensively reflects photovoltaic cell output characteristics under the given working condition. The photovoltaic cell output characteristic modeling method provided by the invention has the beneficial benefits that the established photovoltaic cell model is accurate; data of manufacturers are only utilized during the parameter calculating process, and the parameter calculating algorithm is simple, and is wide in application range; and the explicit model is simple and convenient to use.
