Abstract :
A design of experiment with multivariate regression analysis characterized temperature, humidity and irradiance combined degradation of flexible organic photovoltaic (OPV) modules. This paper presents the method that was used to obtain a multivariate regression analysis with very good explained variance/coefficient of determination R2 of 0.97. The method provides a way to compare modules with a particular architecture, set of materials and process conditions for temperature, humidity and irradiance and their interactions in combination as they influence OPV degradation.
