They're following several lines of development to collect solar energy photovoltaically, (though their favourite future project uses a Stirling Engine instead of PV). Their approach to getting area-efficiency up and cost down is to make the actual PV very small but concentrate sunlight from a wider area onto it by steerable mirrors that track the sun.
It obviously pays-back best in very sunny climates but one day no doubt such technology could be optimised for UK, especially if as expected we get hotter summers.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=156&Focus=14573#Comment_14573 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=156&Focus=14573#Comment_14573 Sun, 17 Feb 2008 16:59:17 +0000 Bluemoon

Air temperatures have no relationship to the amount of solar radiation received per square metre. No amount of global warming changes the latter - an amount purely determined by latitude. Of course, if the UK received more sunshine hours, that would have an effect, but the amount of energy per square metre stays the same.

[quote]GGE has placed initial orders with Emcore Corporation US to supply 215MW / 6.2 million of their world leading 38% efficient triple junction cell receiver assemblies[/quote]

The Emcore Corm web site suggests their triple junction cell is just over 28%

36% including the concentrator lens?..
