Device optimization for integration of thin-film power electronics with thin-film energy-harvesting devices to create power-delivery systems on plastic sheets

摘要

Large-area electronics, through the integration of energy-harvesting devices and TFTs, can provide complete powering systems with embedded power electronics on large, flexible sheets. The performance and application range of such systems depends strongly on the characteristics of TFTs and harvesting devices. We explore device constraints and show how novel thin-film circuit topologies, and their optimization (enhanced by large-area passive components), can mitigate these constraints. Two power-inversion systems serve as vehicles for analysis.
