SunPower's Solar Panels Enter The Guinness Book

I didn’t know the Guiness Book awards solar cell efficiencies lately. This story I read on Cleantechnica tells how SunPower, “the most popular solar panels company in California,” got into the Guinness Book for providing people with “the most efficient commercially available photovoltaic modules on the market.”

HERIC Topology: How a Brilliant Idea Brought 99% Efficiency For Solar Panel Inverters

Brilliant ideas usually don’t need years of hard labor, or at least so it happens most of the time. For example, by implementing a switching trick to a DC to AC current converter used in solar panels, Heribert Schmidt, an electrical engineer (with a doctorate), from the Fraunhofer Institute for Solar Energy Systems has managed to halve inverter losses, bringing the efficiency to 98 percent.

TenKsolar's New Technology Makes Rooftop Solar Panels Shadow-Proof

As you may already know, solar panels are great, but they have one big drawback: if as little as one shadow covers one of the cells, the entire power output slumps. Not to mention that if one of the cells themselves brakes down, the whole system crashes. To hear of such sensitivity in a technology of the future is rather disappointing, but TenKsolar can take up the challenge and solve these issues.

Wake Forest Researchers Develop Polymer-Based Solar PV & Thermal Device

Infrared light makes up the most part of the light spectrum, but the glitch in today’s solar panels is that they can’t really harvest it for direct electricity generation, because of the long wavelengths involved. Thus, a standard solar panel misses about 75% of the incoming energy, and some of them, concentrated solar cells, need cooling to prevent damage to the silicon substrate that favors the energy conversion.
