Abstract
A surface of a photovoltaic cell is coated with a solution that includes barium titanate to reduce reflection of sunlight that is incident on the surface. The solution may include a base of polydimethylsiloxane and carbon nanotubes. The process may be used in the fabrication of new photovoltaic cell assemblies, or to retrofit existing assemblies in situ.
Claims8
A photovoltaic cell comprising:
- a first surface;
- and
- an anti-reflective coating placed on the first surface, wherein the anti-reflective coating comprises a matrix with barium titanate crystals having a variable index of refraction and carbon nanotubes dispersed within the matrix.
A photovoltaic cell comprising:
- a first surface;
- and
- an anti-reflective coating placed on the first surface, wherein the anti-reflective coating comprises polydimethylsiloxane with barium titanate crystals having a variable index of refration and single walled carbon nanotubes dispersed within the polydimethylsiloxane.
