Mouli Cohen on Dye-Sensitive Solar Cells

Mouli Cohen offers his opinion on the development of dye-sensitive solar cells as opposed to its photovoltaic silicon counterparts.

Thanks to an international research team based in Melbourne, Australia, dye-sensitive solar cells can now have a greater energy conversion rate than previously reported tandem dye-sensitized solar cells.

Mouli Cohen, an advocate of the development of green technologies, gives his opinion on this new advancement in solar power harvesting.

Lead by Dr. Udo Bach, scientists at Monash University in Melbourne have collaborated with colleagues from the universities of Wollongong, also in Australia and Ulm in Germany have created a more efficient type of dye that makes the operation of inverse dye-sensitized solar cells much more efficient.

Before this development, the stacking of several solar cells together to maximize energy generation was only possible with photovoltaic cells, and not with dye-sensitized solar cells. Also known as the tandem method, the new solution allows dye molecules to efficiently pass on positive charges to a semiconductor when illuminated with light.

"That specific aspects of technology such as this are being manipulated to come out with breakthrough results is a good sign, indicating the value that the world is finally giving to greener technologies." says Cohen. "It's no longer enough that we can harness the power of the sun, but we can do it more and more efficiently as the years pass."

Indeed, this new method allows for a three-fold increase in energy conversion efficiency when compared to other efforts of creating tandem dye-sensitive solar cells.

"What makes this so significant," adds Cohen, "is that dye-sensitive solar cells are so much easier and more affordable to produce. Although this technology seems far from commercialization, it does present another avenue towards the 'carbon-neutral' and practical generation of energy."

Admittedly, dye-sensitive solar cells currently perform less efficiently than their expensive silicone counterparts. However, things are looking up, as Dr. Bach’s findings are considered an important milestone in the ongoing development of viable and efficient solar cell technology.
