In recent years, building integrated photovoltaic (BIPV) applications have gained not only the considerable interest, but also becoming widespread over the world. Different semi-transparent photovoltaic transparency levels can be used in such applications. This thesis aims to investigate the energy performance and utilization of a CdTe thin-film based semi-transparent PV in automotive world. Outdoor experimental setup was built in Avigliana, Italy, in order to investigate the performance of 35%, 25%, 20% and 5% CdTe thin-film based semi-transparent photovoltaic panels. The comparison was made with panels mounted with inclination of 89 deg., following the glass inclination of an electric bus, implied by Turin public transportation company.
