Abstract
Abstract A hybrid solar energy collecting device adapted to generate an electrical current from sunlight and also to collect in an electrically insulating fluid thermal energy generated by such cells. The solar energy collecting device comprises a duct adapted for guiding the flow of an electrically insulating fluid such as air, and one or more photovoltaic cells mounted on an electrically insulated portion of the exterior surface of the duct. At least one of the photovoltaic cells has a heat sink which extends into the interior of the duct and is adapted to be contacted by the electrically insulating fluid.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
73 words
A solar energy collecting device, comprising a duct adapted for guiding the flow of an electrically insulating fluid, at least a portion of said duct being formed from electrically insulating material, and at least one photovoltaic cell mounted on said portion, said at least one cell having heat conducting means extending into the interior of said duct to a position in which it is adapted to be contacted by said electrically insulating fluid.
Claim 2
Dependent Claim
73 words
A solar energy collecting device, comprising a duct adapted for guiding the flow of an electrically insulating fluid, at least a portion of said duct being formed from electrically insulating material, and at least one photovoltaic cell mounted on said portion, said at least one cell having heat conducting means extending into the interior of said duct to a position in which it is adapted to be contacted by said electrically insulating fluid.
Claim 3
Dependent Claim
21 words
A device according to claim 1, further including means for providing a flow of said electrically insulating fluid through said duct.
Claim 4
Dependent Claim
28 words
A device according to claim 1, wherein said heat conducting means of said at least one cell extends through an aperture in the exterior surface of said duct.
Claim 5
Dependent Claim
15 words
A device according to claim 1, wherein said heat conducting means is a heat sink.
Claim 6
Dependent Claim
26 words
