Nano sandwich boosts solar efficiency by 175%

One of the main reasons that solar cells aren’t more efficient at converting sunlight into electricity is because much of that sunlight is reflected off the cell, or can’t be fully absorbed by it. A new sandwich-like material created by researchers at Princeton University, however, is claimed to dramatically address that problem – by minimizing reflection and increasing absorption, it reportedly boosts the efficiency of organic solar cells by 175 percent.

Developed by a team led by electrical engineer Prof. Stephen Chou, the material is known as a “plasmonic cavity with subwavelength hole array” or PlaCSH.

It is always encouraging to see an improvement. Even so, a boost from say 7 percent efficient to 12 or 13 percent efficient is a tad underwhelming.

We need to see a 500 percent improvement. Then we can talk industrial strength photo-voltaic conversion.
