Electriciteit uit tandpasta
Een beetje gecopieerd van de electriciteit uit aardappelschillen ;-)

The Technology – DYE SOLAR CELLS
DSC technology can best be described as ‘artificial photosynthesis’ using an electrolyte, a layer of titania (a pigment used in white paints and tooth paste) and ruthenium dye deposited on glass, metal or polymer substrates. Light striking the dye excites electrons which are absorbed by the titania to become an electric current many times stronger than that found in natural photosynthesis in plants. Compared to conventional silicon based photovoltaic technology, Dyesol’s technology has lower cost and embodied energy in manufacture, it produces electricity more efficiently even in low light conditions and can be directly incorporated into buildings by replacing conventional glass panels or metal sheets rather than taking up roof or extra land area.

Overigens ontworpen door de Zwitser Michael Grätzel die nog zeer actief is op dit vlak oa met de combinatie waterstof/zonnecel gebaseerd op de hierboven genoemde Graetzel cel.
