The Influence of the Silicon Photovoltaic Panels Spectral Response on the Seasonal Variations of the Photocurrent

A comparison of seasonal and diurnal variations of the photocurrent of different types of PV panels is done for cloudless conditions. PV-panels made of amorphous and crystalline silicon are compared. A simple two-component model of seasonal and diurnal variations of atmospheric transparency is proposed. Every model component is responsible for the peculiarity of spectral sensitivity of the PV-panel material.
