[pdf] PVT collectors combine the generation of solar electricity and heat in a single component, and thus achieve a higher overall efficiency and better utilization of the solar spectrum than conventional PV modules. Photovoltaic cells typically reach an electrical efficiency between 15% and 20%, while the largest share of the solar spectrum (65% - 70%) is converted into heat, increasing the temperat. OverviewPhotovoltaic thermal collectors, typically abbreviated as PVT collectors and also known as hybrid solar. .
PVT collectors generate and electricity basically free of direct and are therefore regarded as a promising to supply and to buildings and industri. .
The range of applications of PVT collectors, and in general , can be divided according to their levels: • low temperature applications up to 50 °C• medium te.
