MECHANICALLY STACKED SOLAR TRANSMISSIVE CELLS OR MODULES
A device is provided. The device includes mechanically stacked layers. The mechanically stacked layers include a bottom layer and upper layers. Each upper layer includes a transmissive solar cell that converts light energy into electricity. Each upper layer transmits unconverted portions of the light energy towards the bottom layer. The bottom layer includes a solar cell that converts the unconverted portions of the light energy into electricity.
1 . A device comprising:
at least two mechanically stacked layers comprising a bottom layer and one or more upper layers,
wherein each of the one or more upper layers comprises at least one transmissive solar cell configured to convert light energy into electricity and pass unconverted portions of the light energy towards the bottom layer, and
wherein the bottom layer comprises at least one solar cell configured to convert at least part of the unconverted portions of the light energy into electricity.
