Panasonic is reporting a 25.6 percent conversion efficiency for its HIT (Heterojunction with Intrinsic Thin layer) solar cells. This is an improvement of 0.9 percentage points over the 24.7 percent conversion efficiency Panasonic achieved in February 2013, with the company claiming it as a world record for crystalline silicon-based solar cells of a "practical size."  Read More

A new Perovskite solar cell has been found have light absorbing and light emitting propert...

When looking for the best materials with which to construct a solar cell, the obvious preference is for one that absorbs light, not emits it. But researchers from Nanyang Technological University in Singapore have discovered a material that does both. Amongst a variety of potential applications, the researchers say the material, Perovskite, opens up the possibility of mobile devices with displays that double as solar cells.  Read More

Microscope photo of tungsten diselenide samples connected to electrodes

Graphene, the two-dimensional lattice of carbon atoms, may be the wonder material du jour, but ultrathin layers of other elements are also proving to be an exciting area of research. One-atom-thick sheets of germanium and tin have shown potential as semiconductors and a topological insulators respectively, and now ultrathin layers of tungsten and selenium have been used to create a diode that could be used in ultrathin, flexible, semi-transparent solar cells.  Read More

Facebook is reportedly looking to buy solar-powered drone company Titan Aerospace to help ...

Titan Aerospace's Solara, a solar-powered unmanned aerial vehicle designed to cruise at an altitude of 20 km (12.42 miles) for five years at a time, certainly got our attention back in August, and it appears to have not gone unnoticed by some of tech's bigger players either. Facebook is reportedly in talks to acquire the company with a view to using the drones as a means of providing internet access to the world's under-served regions.  Read More

This colorful American flag is in reality a functional  and transparent solar cell (Photo:...

A beautiful stained glass installation, a colorful billboard, or rows of windows on an office building ... all as electricity-generating solar cells? New research at the University of Michigan gives a method for creating such transparent and colorful solar cells using a hybrid silicon/organic composition, and furthermore avoids some of the problems of previous colored and transparent solar cells.  Read More

Researchers are claiming a record efficiency of 15.6 percent for a new graphene-based sola...

In 2012, researchers from the University of Florida reported a record efficiency of 8.6 percent for a prototype solar cell consisting of a wafer of silicon coated with a layer of graphene doped with trifluoromethanesulfonyl-amide (TFSA). Now another team is claiming a new record efficiency of 15.6 percent for a graphene-based solar cell by ditching the silicon all together.  Read More

The C-Max Solar Energi Concept uses solar panels on its top for charging

A plug-in hybrid car sounds like an excellent way of squaring the circle between the green cred of an electric car and the range and reliability of one that runs on petrol, but what if you live somewhere that’s a bit off the grid? Ford’s answer is its C-Max Solar Energi Concept, which makes its debut at CES next week. The car uses a combination of high-efficiency solar panels and a separate frame roofed with a Fresnel lens to concentrate sunlight on the panels to give it a proper charge without using the engine or plugging into the electrical mains.  Read More

RUB researchers have developed a bio-based solar cell using cyanobacteria found in hot spr...

Researchers at Ruhr-Universitat Bochum have created a bio-based solar cell capable of generating a continuous electrical current of several nanowatts per sq cm. The new approach avoids damage to the tapped photosynthetic cells, an issue that has plagued previous attempts to harness nature's "power plant."  Read More

The TURANOR PlanetSolar cruises past Tahiti

Solar technology has evolved beyond just your grandpa's big, bulky photovoltaic panels on the roof. Advances in flexible, hyper-efficient and nano-scale materials of late has made it possible for solar cells to begin popping up in all kinds of shapes and places you might not expect. Here's a quick rundown of some surprising spots where solar technology dwells – be sure to flip through the gallery to get a full grasp on the scale of the increasingly solar-powered landscape.  Read More

Spectrolab has achieved a new world record efficiency for a multi-junction solar cell (Pho...

Spectrolab has set a new solar cell efficiency record of 38.8 percent for a ground-based multi-junction solar cell. The new world record doesn't exactly smash the previous mark of 37.8 percent, which was also set by Spectrolab, but is welcome news in a field where every percentage point counts.  Read More
