Claim 1
Independent Claim
24 words
A photovoltaic material comprising: an open-cellular foam material having an internal surface area; and a photoelectric material layer on said foam's internal surface area.
Claim 2
Dependent Claim
24 words
A photovoltaic material comprising: an open-cellular foam material having an internal surface area; and a photoelectric material layer on said foam's internal surface area.
Claim 3
Dependent Claim
12 words

Claim 5
Dependent Claim
19 words
The material of claim 3 wherein said foam includes within its composition a radioactive material and a luminescent material.
Claim 6
Dependent Claim
97 words
An electric current generating cell comprising: a container; an open-cellular foamed material held within said container; a coating on the interior of the cells of said foam of a semiconductor or other type photoelectric junction material; a first pole electrode interconnected to said coating, said pole extending out of said container; a fluid or gaseous activating material entered into said open cells in said foam adapted to interact therewith for the production of an electric current; and a second pole electrode in said container in contact with said activating material, said pole extending out of said container.
Claim 7
Dependent Claim
97 words
An electric current generating cell comprising: a container; an open-cellular foamed material held within said container; a coating on the interior of the cells of said foam of a semiconductor or other type photoelectric junction material; a first pole electrode interconnected to said coating, said pole extending out of said container; a fluid or gaseous activating material entered into said open cells in said foam adapted to interact therewith for the production of an electric current; and a second pole electrode in said container in contact with said activating material, said pole extending out of said container.
Claim 8
Dependent Claim
51 words
The cell of claim 5 further including: a luminescing material in said activating material; an area in which said activating material is circulated and exposed to a light source to activate same; and means for said activated luminescing material to be in proximity with said internal open cells of said foam.
Claim 9
Dependent Claim
28 words
The cell of claim 6 wherein said second pole electrode comprises a grid of open-cellular foamed material in proximity to said coated open-cellular foamed material in said container.
