Solar power is up there as the quintessential clean energy and there’s a race worldwide to develop better solar cells to overcome current challenges related to cell efficiency, manufacturing costs, durability and materials, among other things. One of the latest developments in the sector comes from Northwestern University where researchers have developed a stable dye-sensitized solar cell that may one day prove cheaper than silicon-based cells.
It’s no big mystery why turtles and other reptiles bask in the sun – being cold-blooded animals, they’re gathering heat to warm their bodies, so they can be active. Recently, however, scientists from Israel and the UK discovered that the Oriental hornet has been putting a “high-tech” spin on that model... the outer layers of its body work as a natural photovoltaic cell, converting sunlight to electricity. The scientists then proceeded to create a cell of their own, using the hornet as their inspiration.
In a world first, an international research team based in Melbourne, Australia, has developed a way to boost the output of the next generation of solar cells by creating a more efficient dye that makes dye-sensitive solar cells (DSSC
) perform better than previous versions.
