Gallery: Off-the-Shelf Dyes Increase Solar Panel Absorption

 

The hippies were the first to push solar energy en masse in the 70’s, so it’s a wonder we haven’t thought of this before — it turns out the same stuff used to tie-dye t-shirts can increase the efficiency of solar panels. A new paper released in the Journal of Renewable and Sustainable Energy details the discovery that many common off-the-shelf dyes — as well as dyes used in the medical and food industry — can make solar panels more effective when mixed properly. The researchers basically use the dye to change the color spectrum that the panel can absorb, thereby increasing its efficiency by as much as 8%.

    […] recently reported on researchers that are using off the shelf dyes to help solar cells absorb a wider range of light but this experiment goes even further. No color […]

    Sorry the photos do have nothing in common with the described technology namely DSSC – there are at least a-Si cells in between
