Mask-programmable on-chip photovoltaic cell array

Abstract

We propose a gate-array style easy configuration method for voltage photovoltaic cell for rapid prototyping of on-chip IoT system. Using the same design chips fabricated by standard CMOS process and only changing the mask pattern for post processes, we successfully achieved two type chips: one generates 68 V open circuit voltage output photovoltaic cell and the other does 10 times higher short circuit current than it with 5.4 V open circuit voltage output.
