Sea tangle extract offers power conversion
After years of using platinum, scientists suggest they could one day use extracts from marine plants to replace it in solar cells.
Dye-sensitized solar cells (DSCs) are quickly becoming a widespread and affordable alternative to photovoltaic solar cells. With this change of direction, it is pertinent that DSCs are made to be as efficient and inexpensive as possible for the mass market.
Platinum is traditionally used as the electrode material in DSCs, which, although it shows impressive performance, is not environmentally friendly and has high production costs.
Now, Tingli Ma and co-workers based in China, Japan and Switzerland have expanded their research on natural dyes and biomass manipulation to see if sea tangle, a common marine plant, is a suitable source of raw materials for DSCs. And their results look promising.
