Claim 5:
6. A photovoltaic window pane comprising:
a sheet of transparent poly(methyl methacrylate) having a thickness in the range of 4.0 mm to 12.0 mm wherein said sheet includes a plurality of slots, having a depth of 1.5 mm to 8.0 mm and a width of 0.2 mm to 2.0 mm and a refractive index of 1.49;
one or more photovoltaic cells inserted in said plurality of slots; and
optically coupling fluid positioned in said slots and encapsulating said one or more photovoltaic cells wherein said optically coupling fluid remains in a fluid state and wherein the refractive index of said optical coupling fluid has a value in the range of 1.48 to 1.69″ wherein light passing through said optically coupling fluid and contacting said one or more photovoltaic cell generates electrical power;
wherein said optically coupling fluid comprises phenyl methyl polysiloxane.
