This is a most excellent place for technology news and articles.
PV Magazine is more or less an outlet for press releases by companies trying to innovate (often in air quotes) with photovoltaics. I'm honestly not even sure why it's allowed here; it's completely uncritical. May as well cite a press release on the manufacturer's website at that point instead of laundering it through a magazine.
