Abstract: The invention relates to concentrated photovoltaics for thin film solar cell devices. The thin film solar cell device 100 comprises a substrate 10 with one or more thin film radiation absorbers 12 and a cover 20 which covers the substrate and the absorbers. Mounted to this is an integrated optical system 14, comprising at least one optical element 16 used for concentrating the light onto the solar cell. The optical element 16 and the corresponding radiation absorbers 12 are aligned with respect to their optical axis 24, such that an incoming radiation 22 is directed onto the radiation absorber 12 by the optical system 14. The device can have a second optical system 18 which is arranged between the first optical element and the radiation absorbers. The first optical system may be integrated at a top surface of the cover medium, and can comprise of a lens array, whilst the second optical system can comprise a light guide. The second optical element can be integrated with the top of the radiation absorbing device.
