The term "photovoltaic" literally means "light-electricity". This technology arose in the 1950s and currently has great possibilities of making contributions in the transition towards sustainable development in the building sector. To this end, the challenge for the Sunglass project is to boost the use of photovoltaic solar energy by means of increasing the performance of the currently existing solar panels (their performance goes up to 15 % now).
Research carried out to date has focused on modifying the semiconductor material to make use of a greater part of the solar spectrum. Nevertheless, the Sunglass project puts forward an alternative approach, involving the "conversion of frequencies" phenomenon — based on absorbing photons of certain frequencies and emitting another range of frequencies.
Study on photoactive compounds
Various photoactive compounds were investigated for the project. The objective was to determine their capacity to absorb high-frequency radiation in order to subsequently emit it at ranges more effective for solar cells, as well as the possibility of implementing these materials in the glass coating of solar panels. These compounds were used to develop the special glass for these photovoltaic applications. In this way, substituting the current glass of solar panels by the new product, an increase in energy efficiency was obtained.
By means of the "conversion of frequencies" produced by the glass, the radiation incident on the solar cells is more effective and gives rise to a significant increase in their efficiency (about 2-3 %), and which will have huge repercussion in the building industry.
This new technique will boost the production of clean energy without acoustic contamination and will avoid greenhouse effect gas emissions, besides being able to be used as a complement to other energy sources and provide great flexibility in its applications.

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...

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...
