Highly Transparent, Self-cleaning, and Antireflective Nanoparticle Coatings
… light, reducing the power output of the panel. Antireflective coatings can be used to allow more light to enter the panel to be converted into usable electricity. However, no solid thin film materials exhibit a low enough index of refraction to serve as antireflective coatings for common solar …

Biomimetic nanostructured surfaces for antireflection in photovoltaics
… losses at peak irradiance, compared to an ideal antireflective surface, of only 1%. The potentially more scalable technique of nanoimprint lithography is also used to fabricate antireflective moth-eye arrays in silicon, over areas as large as 1 cm2, demonstrating great potential for stealth and …

Structural and functional characterization of nanoporous thin films through advanced scanning-transmission electron microscopies and optical spectroscopies
… the growth angles and parameters, OAD broadband antireflective coatings based on Si, Ge or SiO2 OAD films have been designed, manufactured, and extensively characterized with the aim of maximizing the performance of the optical elements in the vis-IR wavelength range. This same approach has also …

Porous Silicon as Broadband Antireflector for Photovoltaic Application.
… peak. This type of porous silicon can be used as antireflective coatings in industrial solar cell processing as a replacement for commonly use chemical vapor deposited antireflection coatings which have a reflectance of 10%. Future work can include optimization of anodization parameters to obtain …
