Japanese company develops a solar cell with record-breaking efficiency
I'm not sure I like this. It seems that we're very clearly in the area of diminishing returns when it comes to solar panels.<p><a href="https://upload.wikimedia.org/wikipedia/commons/4/42/Efficiency_chart_rev_05-2012.png" rel="nofollow">https://upload.wikimedia.org/wikipedia/commons/4/42/Efficien...</a><p>The conclusion of that chart seems to be : concentrated solar power (even on small scale) is unbeatable, and tops out (realistically) at ~40% efficiency.<p>So now we should probably work on very, very cheap lenses if we want to advance solar panels, and quick ways to make small, very cheap panels.
