Abstract
An energy conversion device includes a holographic lens arranged between a glass slab and the first solar cell. The holographic lens is configured to concentrate a portion of a first component of impinging electromagnetic radiation onto the first solar cell and direct a portion of a second component of the electromagnetic radiation away from the first solar cell. The first solar cell is a back contact solar cell configured to convert the first component of the electromagnetic radiation into electrical energy.

An energy conversion device comprising:
- a holographic lens arranged between a glass slab and the first solar cell, wherein
- the holographic lens is configured to concentrate a portion of a first component of impinging electromagnetic radiation onto the first solar cell and direct a portion of a second component of the electromagnetic radiation away from the first solar cell, and
- the first solar cell is a back contact solar cell configured to convert the first component of the electromagnetic radiation into electrical energy.
An energy conversion device comprising:
- a holographic lens arranged between a glass slab and the first solar cell, wherein
- the holographic lens is configured to concentrate a portion of a first component of impinging electromagnetic radiation onto the first solar cell and direct a portion of a second component of the electromagnetic radiation away from the first solar cell,
- the holographic lens is a single-layer holographic lens including a holograph printed onto the glass slab, the holograph including a polymer material,
- wherein the first component of electromagnetic radiation includes visible light, and the second component of electromagnetic radiation includes at least one of infrared light and ultraviolet light, and
- the first solar cell is a back contact solar cell including at least one solar cell stripe arranged between the holographic lens and an electrical connector, the first solar cell being configured to convert the first component of the electromagnetic radiation into electrical energy.
A method of making an energy conversion device, the method comprising:
- roll printing a hologram directly onto a glass slab in a pattern that forms a holographic lens;
- arranging the holographic lens between the glass slab and a first solar cell;
- and
- arranging the first solar cell such that at least one solar cell stripe of the first solar cell is arranged between the holographic lens and an electrical connector, the electrical connector being electrically connected to the at least one solar cell stripe.
