(Phys.org) —Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials.
Self-cleaning, antireflective coating mimicks the structure of moth eyes
(Phys.org) —Porous films, which use similar properties to those seen in moth eyes in combination with nanoparticles, are being developed into robust, self-cleaning antireflective coatings for use on both ...
Charge separation understanding could result in cheaper, more efficient organic solar cells
The goal of making cheap organic solar cells may have gotten a little more approachable with a new understanding of the basic science of charge separation presented in a paper published online today, February ...
New solar cell technology captures high-energy photons more efficiently
(Phys.org) —Getting the blues is rarely a desirable experience—unless you're a solar cell, that is.
'Inverse opal' structure improves thin-film solar cells
(Phys.org) —Researchers have shown how to increase the efficiency of thin-film solar cells, a technology that could bring low-cost solar energy. The approach uses 3-D "photonic crystals" to absorb more ...
