HCPV modules of SMALFOC design in versions for PV and PV/T operation

The recently developed HCPV modules of SMALFOC design (Small lenses, Multijunction cells, All from glass, Lamination, Fresnel, Optics, Concentration) are characterized by structural and technological similarities with flat plate modules. In the paper, two variants of module usage are considered: (i) version for an “ordinary” generation of electricity; (ii) version for operation as a hybrid system, where a combined PV/Thermal approach is realized for producing both electricity and heated water. Water as a heat removing fluid is made to flow through a flat structure applied to the laminated back side of a HCPV module. PV and PV/T performances of the modules at different operation conditions are presented.
