The UCLA team describes a new kind of polymer solar cell (PSC) that produces energy by absorbing mainly infrared light, not visible light, making the cells nearly 70% transparent to the human eye.

Powered by 2-cell lithium polymer rechargeable batteries, the detachable wireless satellite speakers offer up to 10 hours of non-stop playback and can be easily recharged by connecting them back to the main unit.

Under a defence contract, Dr Claus's laboratory is testing a photovoltaic cell constructed from films of polymer and ceramic which feels as flexible and hardy as cloth.

Dr Claus has already used this process to make a flexible kind of photovoltaic cell, made from alternating polymer and ceramic layers, that can be sewn on the outside of a tent.

Polymer solar cells have attracted great attention due to their advantages over competing solar cell technologies.

The near-infrared photoactive polymer absorbs more near-infrared light but is less sensitive to visible light, balancing solar cell performance and transparency in the visible wavelength region.

Once these polymers come into contact with water in or on the body, they self assemble into a new polymer structure that is designed to target bacteria membranes based on electrostatic interaction and break through their cell membranes and walls.
