I am not sure if my previous post on this went through on this... but it is too good to not share around.


It may not be news to this forum, but a search of the posts shows no mention of it.. so here goes:

I was watching a repeat of an Australian Science show "Catalyst" some weeks ago with a story refering to a solar technology being developed by the Australian National University [anu] and Origin Energy.


The cells use "slivers" (small slices) of silicon rather than expensive whole silicon wafers. The result is a dramatic reduction of costs, as well as an improvement in efficeny in low light situations.

Aparently there is a lot of waste in a normal cell - and they can fit 700-800 cells in one large wafer.

Additionally, if I understand it right, they claim that where a normal cell starts working when it is 40-60% exposed to light, these start producing at 10%.

The best bit: the cost is dramatically reduced.

Payback for cell purchases is expected to reduce to 5 years!


The test plant that Origin Energy has built as a proof of concept has started to build these things - and they claim to have residential production occuring in 12-24 months!


I want to get my hands on some of these babys! I haven't found where I can buy some... yet!

Same as before, I don't see the point seems like vaporware?
