Hi Everyone, Thank you for all your suggestions, which fall into two categories: ITO and CNT. We have used ITO, and although it is easy to apply, it does not have the optical characteristics that we need because the index of refraction is too high. Carbon nanotubes have better optical properties. Does anybody know of a service that can apply CNT? A third possibility that I am aware of is P3HT embedded with carbon nanoparticles. Are there other possibilities out there that we are missing?

This would have to be fairly low temperature process due to the low melting point of the plastic. The sheet resistance requirements are not too rigorous, anything under 400 ohms/square should be fine. Optimally, it would need to be >99% transmissive over 400-1100nm wavelength range, but at this point >80% is acceptable. > > Thanks for your help. > > Brad Cantos
