A cost-effective lateral beam splitting photovoltaic system coupling a Si cell and a InGaAs photodiode through a long-pass dichroic filter has been designed, manufactured and tested under illumination with a Sun simulator and direct solar irradiation. Two filters with different cut-off wavelengths have been considered: 950nm and 1100nm, best efficiencies are achieved with the 950nm cut-off one due to lower reflectance losses in the high energy spectral range. The system, read-out in two-terminal configuration both in parallel and in series, proved to double the efficiency of the Si cell alone in case of high air masses.

Abstract
A cost-effective lateral beam splitting photovoltaic system coupling a Si cell and a InGaAs photodiode through a long-pass dichroic filter has been designed, manufactured and tested under illumination with a Sun simulator and direct solar irradiation. Two filters with different cut-off wavelengths have been considered: 950nm and 1100nm, best efficiencies are achieved with the 950nm cut-off one due to lower reflectance losses in the high energy spectral range. The system, read-out in two-terminal configuration both in parallel and in series, proved to double the efficiency of the Si cell alone in case of high air masses.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
