For some years now, scientists have been exploring the use of quantum dots as the basis for a novel type of solar cell. The advantages over conventional solar photovoltaic cells are numerous, minus one aspect: efficiency, which is actually the most important one. A new technique developed at MIT labs that uses quantum dots in [...]

I recently came across a great article discussing solar photovoltaic (PV) efficiency. You can read it in its entirety on this website - here’s the gist. When people hear that the typical efficiency for solar power is somewhere around 15%, or even as low as 12% for organic photvoltaics, they scoff and start to mumble that [...]

This has the potential to be the holy graal of solar energy – UCLA researchers have developed a new organic polymer that produces electricity, is nearly transparent and much more resistant than silicone. If you think about solar cells, usually, the blacker the better – the blacker they are, the less energy is lost. But [...]

The new architecture, depicted in the picture below can exceed a 40 percent conversion efficiency, and even when irradiated from the side it generates solar conversion efficiencies that rival, and may eventually surpass, even the most ultra-efficient photovolataics. The new cell was developed by researchers working on the David Ben-Gurion National Solar Research Center, and [...]

If you’re reading this post via e-mail or RSS, please visit the post’s page on the website to view the video interview. MIT researchers, guided by Andreas Mershin’s vision of a world fueled by cheap and renewable electricity, have recently published a paper in which they explain how photovoltaic panels made from plants can be [...]
