solar cell search update - found!

KTP:
hi guys,

I think I have found the answer to my quest for a high efficiency multijunction solar cell/panel for some low power microcontroller designs.  The new panel I was just sampled is a pre-production prototype made up of 10 cells and is fracking amazing.  It is super thin, light and small, but not really fragile.  It is about 3.6 grams, a little smaller than a business card (and about twice as thick) and produces over 5V at 80mA in full sun!  In a indoor room with a single 100 watt bulb 8 feet away it produced 156uW at 2.75V....a surplus of power for something like the MSP430.  I have a polycrystaline panel about 8 times as heavy and 50% larger which doesn't produce 1/3 this power!

I only have the one sample, but full production is supposed to start this year, but that probably really means maybe these will be available next year sometime.

Very nice. Any info about the price?

KTP:
not really any price info, except that they may need to be purchased in cases of 500 or so  :-\

EEV blog group buy anyone?

I've heard that a few hundred times in my career.  ;D

But... if they do manage to get into production, I'd be interested in a few.
