An efficient moisture-electric-energy transformation is discovered by means of establishing an oxygen functional group gradient in a graphene oxide film. The moisture variation serves as energy source to generate electric power with energy-conversion efficiency up ≈62%. Based on this finding, prototype generator and self-powered respiratory monitor are demonstrated under the stimulus human breath.
In this work, we demonstrate that the performance of c-Si/ZnO heterojunction ultrathin-film solar cells (SCs) is enhanced by an integrated structure c-Si trapezoidal pyramids on top a active layer and Al in back electrode.
