Flexible and semi-transparent thermoelectric energy harvesters from low cost bulk silicon (100)

Abstract

Flexible and semi-transparent high performance thermoelectric energy harvesters are fabricated on low cost bulk mono-crystalline silicon (100) wafers. The released silicon is only 3.6% as thick as bulk silicon reducing the thermal loss significantly and generating nearly 30% more output power than unpeeled harvesters. This generic batch processing is a pragmatic way of transforming traditional silicon circuitry for extremely deformable high-performance integrated electronics. © 2013 WILEY-VCH Verlag GmbH & Co.
