Researchers Claim New Solar Panel Can Collect 90% of Sunlight From Any Angle

With some news straight out of the “didn’t we just hear about something like this?” file (we did), some groundbreaking research has revealed that a near perfect solar panel has been created.

Scientists at the Rensselaer Polytechnic Institute have allegedly found a process that allows them to trap nine out of ten photons that hit a solar panel, providing a 90 percent collection rate. A new anti-reflective coating for the panels provides grounds for creating solar panels that don’t have to change their angle in order to collect energy.

With current technology, the photon absorption rate stands at an already impressive 67.4 percent, with the variable of whether or not the sun is actually hitting the cells. But the new cells which according to Shawn-Yu Lin, the man responsible for the project, function like a “dense forest where sunlight is ‘captured’ between the trees.” This happens through a process that not only involves the new anti-reflective coating, but also the bending of the path of the sunlight to an angle that allows maximum capture of sunlight.

With all possible variables at their best, Lin claims that the cells can capture 96.21 percent of the photons that hit their surface.

avatarCollection rate? How about transfer rate?...

Yeah, yeah, that is an impressive collection rate. But what about the transfer rate? Has this been inproved? No? Then who cares.

avatar There is an efficiency

 There is an efficiency coefficient though. Which (I just checked), stands at 25%. This will undoubtedly raise that somewhat when the two technologies are combined (if they can be).

avatarI believe that the article

I believe that the article is referring to photovoltaic cells, not to solar panels for heating water.  As far as I know, there is no "transfer rate" associated with photovoltaic cells.  There is a heat transfer rate associated with solar panels for heating water.
