Intrinsic amorphous silicon
WebThis process may be similar to Step 603 in FIG. 6. If Layer 1 is a hole transport layer rather than an electron transport layer, Layer 1 could be a metal oxide like MoOx or multiple layers like intrinsic and doped amorphous silicon or SiCh and doped poly silicon. In Step 702, a transparent conductor (Layer 2) is deposited.
