Grätzel Cells Increase Photovoltaic Efficiency
Grätzel cells are photovoltaic devices that take advantage of the interaction of a structured semiconductor less than one nanometre in size and an organic dye that acts as a solar collector. According to Elena Guillén, member of UPO’s Coloides y Celdas Solares Nanoestructuradas (Nanostructured Colloids and Solar Cells) Group, this dye can be either synthetic or natural and can even enable the use of chlorophyll for this type of cell. Thus, researchers at UPO have begun... Read More
