Are Super-Thin Solar Cells The Future? New Solar Cells Developed That Are Pound For Pound Up To 1000 Times More Powerful Than Conventional Photovoltaics

The general drive in the solar energy technology industry has been towards the development of higher solar cell efficiencies and lowered manufacturing costs, but are there other avenues of improvement worth exploring? Such as the development of ultra-thin, ultra-lightweight solar cells? That’s exactly what new research from MIT is suggesting — that the development of […]

Sharp Solar Cell Efficiency Record — Another One (44.4%)

In May, Sharp regained the world’s triple-junction, non-concentrator solar cell efficiency record — 37.9%. Now, it has also taken the overall world solar cell efficiency record — 44.4%. Here’s another guest post from Mathias Aarre Maehlum of Energy Informative on the news. By Mathias Aarre Maehlum A research team at Sharp Corporation has announced that it has created a solar cell […]

Breakthrough In Solar-Powered Hydrogen Generation

This is a guest post from Mathias Aarre Maehlum, who writes more about solar panels at Energy Informative. Enjoy! By Mathias Aarre Maehlum A team of researchers at the National Institute of Standards and Technology has made significant improvements to the process of generating hydrogen from solar energy and water. They have created a PEC-cell (photoelectrochemical) […]

NASA’s New Solar Electric Ion Propulsion Engine — Images Released

NASA recently released a new image of its newest solar-electric propulsion thruster design. The design utilizes xenon ions for propulsion, offering the possibility of a much more efficient means of space travel than chemical rockets can provide. More energy-efficient space travel sounds good, and it’s solar-powered to boot. 🙂

Dye-Sensitized Solar Cell Consortium Launched

The idea of dye-sensitized solar cells has been around for awhile, but they aren’t anywhere near commercially viable, largely due to low efficiency. But maybe someday…. A consortium between a few leading bodies was recently formed in Europe in order to advance the technology. Here’s the press release from 3GSolar: 3GSolar Photovoltaics announced [this month] the […]

Solar & Wind Energy Overview

Here are parts 1 and 2 of a presentation I gave to a class of renewable energy graduate students yesterday (reposted from CleanTechnica): Renewable Energy Big Pic: Part 1 (Including 34 Charts & Graphs) As I mentioned in my article covering the latest US Solar Market Insight report (which I just published a few hours ago), I was “out […]

Current Solar Module Efficiency Nowhere Near Its Potential, Especially Thin-Film Solar & CPV (Chart)

National Renewable Energy Laboratory (NREL) Director Dan Arvizu recently gave a keynote speech during the 2013 International Renewable Energy Conference (part of Abu Dhabi Sustainability Week), which I was lucky enough to attend in January*. His speech covered a large variety of cleantech topics, and most of the points I’ve covered extensively over the years. However, a couple of his […]

Solar = Disruptive Technology (Graph)

I recently ran across this interesting graph on reddit: The title of the article in which the graph was housed (similar to mine above) was: “Solar Energy: This Is What A Disruptive Technology Looks Like.” I think the graph is pretty clear — while the price of retail electricity, residential natural gas, and crude oil […]

Sharp Regains Solar Cell Efficiency Record

Sharp has a long string of solar cell efficiency records. And it has just extended that string a little further. In 2009, Sharp landed a 35.8% triple-junction, non-concentrator solar cell efficiency record. It then went on to break that record a couple more times — with others breaking it as well. Up until recently, that […]
