“World record efficiencies are popping up almost every month, leading the OSC community into an endless and dangerous tendency to outbid the last report,” stated Dennler et al. in the article. “The current outbidding phenomenon does a severe disservice to the whole community, damaging its reputation. Solar cells and especially OSCs face enough difficulties in convincing people of their benefit over other energy sources.”
OSCs are potentially cheap and easy to fabricate. This makes them very attractive in comparison to the familiar silicon solar cells, which struggle to compete in cost with other energy sources. The promise of OSCs means the field is burgeoning. However, OSCs still show relatively low efficiencies that will need to improve significantly before they become a success.
Dennler and colleagues urge the field to press for independent verification of solar cell efficiencies. They call on researchers to question their results and constantly push the accuracy of their findings and ask journal editors to review claims of significant advances thoroughly.
“In essence, this should be a good thing. Increasing the number of people focused on this tremendous renewable will hopefully help solve the planet’s energy needs,” adds Dennler. “Unfortunately, OSCs currently suffer from their own success.”
The increasing number of researchers and choice of where to publish results means that everyone is finding it increasingly difficult to gain an impact within the community. The result is a pursuit of eye-catching claims of solar cell efficiencies.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
