Single junction type (a) and the proposed double junction type (b) solar cells are compared with the conventional TANDEM type (c) and the proposed face-to-face type (d) multi-junction connections. A cross-sectional view of a new AI Robot Vision chip in 3DIC multichip architecture.(e) shows one-pixel unit of a unique high-performance image sensor unit, with the solar cell capability, which is composed of a pinned-surface buried-channel P+PNPP+ double junction photodiode with an in-pixel source-follower current-amplifier, and also with a depletion MOS type charge transfer gate (CTG) and another depletion MOS type pre-charging gate (PCG) with a switching outlet diffusion drain (ODD) region, for draining out the photo signal electrons.
