Abstract
Glasses are widely used in modern society, mostly for achieving brightness for buildings, transportations etc.Here a transparent triboelectric generator (TEG) based on commercially available glasses and polydimethylsi-loxane (PDMS) plates is proposed and fabricated to harvest mechanical energy. Using flat glass and PDMSplates, an open voltage, short-circuit current and power up to 850 V, 20.6 μA and 3.13 mW are achieved fordevices with 5 cm×5 cm dimension, whereas the transparency of glass and PDMS structures exceeds 81% and89%, respectively. The TEGs show excellent mechanical stability and reliability upon cyclical contact for 10,000times. The voltage and power outputs of the glass based TEGs improve with increasing contact force, frequencyand distance, and with decreasing glass thickness and humidity level. Our results demonstrate the feasibility toutilize abundant glass windows to fabricate transparent TEGs for energy harvesting, which could make a greatcontribution to the sustainable development
