The big ideas that are changing everything

Paper Solar Cells

Recent research out of Osaka University is looking to expand the use of solar energy by making cells less expensive and easier to manufacture than ever.

The new solar cells are built on a substrate made of wood pulp, using organic photovoltaics and fine silver conductors. They can be produced using current printed circuit technology and are easier to work with than conventional plastic cells.

A prototype device measuring only 2cm by 5 mm by 1 mm (0.8 x 0.2 x 0.04 inches) generated sufficient energy to power a light bulb. Lightweight and flexible, the new cells possess clear advantages over currently available technology.
