Tubular science improves polymer solar cells

This post was originally published on this site

A popular polymer-based solar cell could produce more energy if the electronic charges can move efficiently through the cell’s components. A novel three-component mixture allows conductive solar cell materials to self-align into columns. The alignment improves the efficiency. This, in turn, allows the solar cells to be fabricated more than three times thicker without degrading the high performance. The greater depth makes the process more compatible with conventional industrial coating processes.
