A flexible, non-flat solar cell comprises a flexible substrate. A pn junction is on or in the flexible substrate. The solar cell has been flexed so as to have a non-flat geometry that results in an increased surface area of the flexed solar cell with respect to the surface area of a flat solar cell that is the same as the flexed solar cell except that the flat solar cell has a flat surface geometry that has the same projected area on a lateral plane as does the flexed solar cell.

Flexibility-assisted heat removal in thin crystalline silicon solar cells

A method and resulting device that mimics the light scattering properties of a random structural pattern using microspheres.

Method and system to mimic a random structural pattern

An optoelectronic device having a self-defrosting/de-icing window configured to operate at an electromagnetic radiation frequency having metals that are optically transparent as a result of the wires having an effective plasma frequency that is equal to or lower than the electromagnetic frequency at which the device operates. The effective plasma frequency of the wire is lowered by configuring the path of the wire between the terminal ends to be meandering, serpentine, U-shaped and in other non-linear configurations. The metal wires are resistively heated.

Defrosting infrared windows using transparent metallic nanostructures

A photonic infrared detector having at least one metal layer having a broad-band IR absorption and the detector is configured to enable light to make a plurality of passes within a c-Si substrate.

Light trapping in hot-electron-based infrared photodetectors

The present prevention provides a surface coating for cooling a surface by light scattering comprising a plurality of successive layers, each of the layers may be comprised of a plurality of spheres arranged to form a structure comprised of packed spheres. Each layer may have a different arrangement of packed spheres to create to a different light scattering property in each of the layers. The coating of the structures may also be formed by randomly packed spheres and the spheres may have a uniform diameter.

Microsphere-based coatings for radioactive cooling under direct sunlight

Provided is a method for fabricating a nanopatterned surface. The method includes forming a mask on a substrate, patterning the substrate to include a plurality of symmetry-breaking surface corrugations, and removing the mask. The mask includes a pattern defined by mask material portions that cover first surface portions of the substrate and a plurality of mask space portions that expose second surface portions of the substrate, wherein the plurality of mask space portions are arranged in a lattice arrangement having a row and column, and the row is not oriented parallel to a [110] direction of the substrate. The patterning the substrate includes anisotropically removing portions of the substrate exposed by the plurality of spaces.

Methods to introduce sub-micrometer, symmetry-breaking surface corrugation to silicon substrates to increase light trapping

An optoelectronic device configured to operate at an electromagnetic radiation frequency having metal wire electrodes that are optically transparent as a result of the wires having an effective plasma frequency that is equal to or lower than the electromagnetic frequency at which the device operates. The effective plasma frequency of the wire is lowered by configuring the path of the wire between the terminal ends to be meandering, serpentine, U-shaped and in other non-linear configurations.
