• Whenever a graphite sheet can be used while the substrate, carbon can diffuse into the Ag level into the subsequent p-i-n process at 200-400 °C. To stop this, we added an oxide layer as a carbon diffusion barrier involving the carbon substrate as well as the straight back reflector. When it comes to carbon diffusion buffer, silicon oxide (SiO2)…[Read more]
