Researchers make progress on photosynthesis-mimicking solar cell

Abstract:
Within the Consolider HOPE project (projects funded by the Ministry of Innovation and Science), a group of scientists at Universidad Pablo de Olavide (UPO), headed by Juan Antonio Anta, are working on the optimization of a type of photovoltaic cell (Grätzel cell) that artificially mimics photosynthesis.

Grätzel cells are photovoltaic devices that take advantage of the interaction of a structured semiconductor less than nanometer 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.
