Within the solar cell, the dye is paintedin a thin layer on a porous titanium dioxide scaffold to collect light and, ina series of steps, create power.

在太阳能电池内，染料涂在多孔的二氧化钛支架上来收集光线，然后经过一系列步骤，就产生了电流。

About 40 years later Charles Fritts, an American inventor, built the first solar cell. Made with selenium and a thin layer of gold, the device was less than 1% efficient.

The all-carbon formula doesn't need to be thickly spread to do its work, and it simply lets visible light through -- it could layer on top of a traditional solar cell to catch many more of the sun's rays.

The system the researchers tested used a type of solar cell known as dye-sensitized solar cells, a lightweight and inexpensive type where the active layer is composed of titanium dioxide, rather than the silicon used in conventional solar cells.
