Abstract
A thin film photovoltaic cell structure (1) comprises a substrate (2); a first dielectric layer (3) on the substrate (2); an active layer (4) on the first dielectric layer (3); and a plasmonic light concentrator arrangement (5) on the active layer (4) for coupling incident light at a first wavelength band into the active layer (4). According to the present invention, the thin film photovoltaic cell structure (1) further comprises a second dielectric layer (6) formed of a dielectric material which is transparent at the first wavelength band and at a second wavelength band on the plasmonic light concentrator arrangement (5); the first dielectric layer (3), the active layer (4), the plasmonic light concentrator arrangement (5), and the second dielectric layer (6) being configured to form a resonant cavity for coupling incident light at the second wavelength band into a standing wave confined in the resonant cavity.
