“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.

Atomic structure of ultrasound material not what anyone expected

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...
Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to...
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
