Estudio y modelado del impacto del espectro solar, el polvo y la suciedad sobre el comportamiento en exterior de los materiales fotovoltaicos

Abstract

This PhD Thesis intends to achieve an improvement in the design of photovoltaic systems through three specific objectives. Thus, it has been verified whether it is possible to biunivocally characterise the shapes adopted by the spectral distribution of direct solar irradiance by a scalar parameter known as average photon energy. The influence of the spectral distribution of incident irradiance on the electricity produced by single junction photovoltaic devices has been modelled from the following parameters: air mass, aerosol optical depth and precipitable water. Finally, the impact of soiling along the absorption band of different photovoltaic materials and its relation to the spectral distribution of incident irradiance on them has been estimated.
