With the first ever production of synthesized "solar" jet fuel, the SOLAR-JET project has successfully demonstrated the entire production chain for renewable kerosene obtained directly from sunlight, water and carbon dioxide (CO2), therein potentially revolutionizing the future of aviation. This process has also the potential to produce any other type of fuel for transport applications, such as diesel, gasoline or pure hydrogen in a more sustainable way.

Researchers at Finland's Aalto University in cooperation with Universitat Politècnica de Catalunya have achieved record-breaking efficiency of 22.1% on nanostructured silicon solar cells as certified by Fraunhofer ISE CalLab.
Black silicon solar cells push efficiency record to 22.1 percent - Electronics Eetimes
Researchers at Rice University have discovered a way of simplifying the manufacture of solar cells by using the top electrode as the catalyst that turns plain silicon into valuable black silicon. Black silicon is silicon with a highly textured surface of nanoscale spikes or pores that are smaller than the wavelength of light. The texture allows the efficient collection of light from any angle, at any time of day. Barron and his team have been fine-tuning the creation of black silicon for some time, but an advance in the manufacturing technique should push it closer to commercialization, claimed Barron.

Scientists have long talked about black silicon (that is, silicon with nano-sized structures) having the potential to trump conventional solar power, and there's now some proof that this is happening. Aalto University researchers have developed black silicon solar cells that achieve a record 22.1 percent efficiency when turning the Sun's rays into usable energy. That's a 4 percent absolute boost over the previous best in black silicon, and good enough that the technology could finally be ready to reach the market and replace existing solar panels. Black silicon is far better suited to collecting sunlight at low angles, which is common in northern regions -- you wouldn't have to live in a sunny, forgiving part of the world to get the most out of clean energy.
Super-efficient solar cells can power homes in unforgiving areas
The South African pilot project mounted by Ripasso Energy of Sweden claims to have achieved the most efficient conversion of solar energy into power – at 34%, nearly double the efficiency of PV technology – and is, according to the Guardian report, ready for commercial deployment. The 100-square-meter dishes track the sun across the sky and focus its heat into a tiny point, which then allows the alternate heating and cooling of enclosed gas in a Stirling engine to drive pistons that turn a flywheel to generate electricity.

Researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) claim to have eliminated pinhole problems in the top layer of next-generation perovskite solar cells that are in development.

WITH so much glass in buildings, cars and the screens of mobile devices, it is understandable why researchers would like to come up with transparent solar cells which could generate electricity and top up batteries.

What will tomorrow’s solar panels look like? Last month, along with colleagues from Oxford and MIT, I published a feature in Scientific American making the case for cheap and colorful solar coatings derived from a new class of solar materials: perovskites. In this post, I’ll critically examine prospects for commercialization of solar perovskites, building on our article’s claim that this technology could represent a significant improvement over current silicon solar panels.
To Succeed, Solar Perovskites Need to Escape the Ivory Tower : Greentech Media
Scientists in Switzerland announced a clean-energy breakthrough on Wednesday; a cheaper, solar technology that splits water molecules to create clean-burning hydrogen fuel. The solar panel design will make it cheaper to produce hydrogen, but a simple version won't be available for average citizens for at least 10 years, scientists said. Splitting water molecules to create hydrogen allows the sun's energy to be more easily stored to generate electricity or power clean cars.

A consortium of eleven European partners in eight countries claims to have an effcient alternative to silicon that achieves 25% efficiency with its Sharc25 (super-high efficiency CIGS thin-film solar cells) program to produce single-junction thin-film solar cells that rival silicon at 25 percent efficiency for a fraction of the cost of the cheap low-efficiency Chinese varieties.
