Lego Brick Solar Cell Use Dye Molecules
Delft University scientist, Annemarie Huijser, uses nature to inspire her research into more cost effective solar cells that position dye molecules, like Lego bricks, to transport a charge more efficiently. ...
... "During her PhD, Annemarie Huijser attempted a partial recreation in solar cells of this process as found in plants. She focused on what are known as dye-sensitised solar cells. These comprise a semiconductor, such as titanium dioxide, covered with a layer of dye. The dye absorbs energy from sunlight, which creates what are known as excitons. These energy parcels then need to move towards to the semiconductor. Once there, they generate electric power. " ...Via Delft University of Technology: Cheap solar cell process
