Hi all.

I read somewhere that a solar cell that is 10% efficient or better can now be printed "roll to roll" in much the same way as an OLED can.

If this is the case, what would be the legal implications of selling a DIY kit online to modify your "steam driven" 2000 era Epson inkjet printer to print these?
I figured that if the CIS units are legal to sell then so should this right?

About the only stumbling block I can see is Epson going lawyer crazy and saying "this is OUR IP, you agreed to use the printer as a printer not as a makerbot etc".

Case in point, Sony and the PS3, PS2, PSP, etc.

Kind regards, -A

The problem with a lot of these solar cells is longevity without hermetic sealing (and UV filtering, but that's easier/cheaper).

Also it's not really necessary ... Mayer rod coating, screen printing, stenciling ... all these techniques are already available cheaply for applying thin and thick films, without all the limitations of consumer inkjet heads (can't handle higher viscosity and limited solvent resistance).

Yeah, same as OLEDs. IIRC that was the main problem with the early displays, I got stung by this.
The trick is to include within the structure a "one way" moisture absorbing system much like a getter on a vacuum tube- in fact some newer OLEDs are finished under vacuum to ensure no water is left at all.

Shame someone hasn't come up with the idea of making glass OLED filled beads with internal antennas and BlinkM like addressing as a form of diffuse wireless lighting and wide area display smile

(scuttles off to the Patent Office)
