In this work the behavior of an organic solar module operating under real solar radiation conditions is presented. This allows to understand which parameters limit the efficiency of an organic device and their underlying mechanisms. The characterization of a module, produced by CSEM Brasil, with active layer P3HT:PCBM, is based on instantaneous voltage and current curves, dark current curves and analysis of the module operating continuously with fixed voltage. This allows to extract the parameters of the equivalent circuit of the module, such as diode saturation current (I-0), series resistance (R-S) and shunt resistance (R-SH) as well as to understand the influence of different levels of radiation and temperature on such parameters. The work presented was performed by using a commercial organic solar module in extensive outdoor experiments. The results are based on continuous use and for several levels of radiation and temperature under real operating conditions in comparison with a theoretical model for the first time. With the continuous tests it was possible to demonstrate the average daily generation of the module in Wh/m(2), and also to verify experimentally, that the module presents better efficiency for diffuse radiation.
