A rumor’s been swirling around the Internet this week that Mark Zuckerberg and Facebook are interested in acquiring solar-powered drone maker Titan Aerospace. The social media giant is rumored to be interested in the drone company to make the Internet truly mobile. Such a purchase could be part of the initiative, which seeks to […] Read more

Top 5 Famous Solar Sites

Some of the most recognizable locations in the world are now becoming world famous solar sites. Solar has yet to go mainstream, but it serves as an icon of progress and technological advancement. Iconic structures and locations – new and old – across the globe are going solar and are reinforcing solar’s iconic nature. The […] Read more

15.6% Efficient Graphene PV Device Developed

Earlier this week  Spanish scientists at the Universitat Jaume I in Castelló’s Group of Photovoltaic and Optoelectronic Devices (DFO) and the University of Oxford published research in the journal Nano Letters showing that they are able to create a graphene and perovskite photovoltaic (PV) device that converts 15.6 percent of the sun’s energy into electricity. While the […] Read more

Graphene Moves Into Solar Cells

Researchers believe that graphene, among its other applications in energy, could be used as a transparent electrode in photovoltaic cells, replacing a layer of indium tin oxide that is brittle and becoming increasingly expensive. Wee Shing Koh of the A*STAR Institute of High Performance Computing in Singapore and co-workers have compared these two materials. They found […] Read more

Polymer Solar Cell Efficiency Goes Ballistic

Researchers from North Carolina State University and the Chinese Academy of Sciences have found an easy way to modify the molecular structure of a polymer commonly used in solar cells. Their modification can increase polymer solar cell efficiency by more than 30 percent (from 5.6% to 7.5%). Polymer-based solar cells have two domains, consisting of an electron […] Read more

Solar Cell Degrades in Real Time

Using X-ray imaging, scientists at the Technical University of Munich (TUM) were able to watch an organic solar cell degrade in real time. These new observations will help scientists to find new ways to increase the stability of organic solar cells. Organic solar cells, especially those based on polymers are inexpensive to produce on a large […] Read more

Quantum Dot Sensitized Solar Cell Hit Efficiency Record

Solar cells made with inexpensive, non-toxic copper-based quantum dots can achieve record longevity and efficiency, according to a study by Los Alamos National Laboratory and Sharp Corporation. “For the first time, we have certified the performance of a quantum dot sensitized solar cell at greater than 5 percent, which is among the highest reported for […] Read more

Solar Pipeline is 43 Gigawatts Strong!

There are enough solar photovoltaic installations in the pipeline to power 6 million households. NPD Solarbuzz, an industry research and analytics firm, found that U.S. solar developers have more than 43 gigawatts of projects in varying stages of planning and construction on the board. While many of the projects won’t be completed, many will and […] Read more

TetraSun: Solar from Copper

The majority of silicon solar photovoltaics use  silver to conduct electricity but thanks in part to help from the National Renewable Energy Laboratory, TetraSun is using copper as a conductor instead of silver. The approach, the results and the cost-savings have helped TetraSun and NREL win a 2013 R&D top 100 award from R&D Magazine […] Read more

Printing OLEDs and Solar Cells is Now A REALITY

Researchers at the Fraunhofer Institute for Applied Polymer Research (IAP), Germany, worked together with mechanical engineering company MBRAUN to develop a production facility able to create inexpensive organic light-emitting diodes (OLEDs) as well as organic solar cells on an industrial scale. Is now possible to print OLEDs and solar cells from solutions containing luminescent organic […] Read more

Perovskite Structures = Cheaper Solar?

Scientists at the Nanyang Technological University (NTU) are using organic-inorganic hybrid perovskite materials to create cheaper and more efficient solar cells. According to them, this next generation solar cells will be about five times cheaper than current thin-film solar cells, due to a simpler solution-based manufacturing process. Perovskites take their name from calcium titanium oxide […] Read more

Silicon Supercapacitor Built by Researchers

Researchers at the Vanderbilt University in Nashville propose a novel silicon supercapacitor design. Such supercapacitor can be, theoretically, integrated into a silicon chip, opening some interesting options for energy storage. Batteries effectively store energy but do not deliver power efficiently because the charged carriers move slowly through the solid battery material. Capacitors, which store energy […] Read more

Space-Based Solar Power: Japan is a Believer

A couple common criticisms of solar power here on our beautiful planet are that it becomes useless at night and not all places receive high amounts of solar insolation.  That is to say that the Mojave Desert in California is a more attractive candidate for photovoltaic power than putting solar panels on roofs in Berlin, […] Read more

Advanced Crystalline Silicon Solar: Will it Hit $1/Watt?

Advanced crystalline silicon technologies are the most likely to achieve the US Department of Energy SunShot Initiative goal of reducing the cost of solar to $1 per installed watt, according to a recent report from Lux Research. While silicon solar cells are unlikely to meet that milestone by the 2020 goal, emerging advanced silicon technologies […] Read more
