Abstract
Thermoelectric materials embedded through or inside exterior glass windows can act as a viable source of supplemental power in geographic locations where hot weather dominates. This thermoelectricity is generated because of the thermal difference between the high temperature outside and the relatively cold temperature inside. Using physical vapor deposition process, we experimentally verify this concept by embedding bismuth telluride and antimony telluride through the 5 mm Plexiglas to demonstrate 10 nW of thermopower generation with a temperature gradient of 21 °C. Albeit tiny at this point with non-optimized design and development, this concept can be extended for relatively large-scale power generation as an additional power supply for green building technology.
Highlights
Thermoelectric generation has recently emerged as a significant candidate in the area of renewable and sustainable energy harvesting
Our indirect approach of curing a larger Plexiglas panel from individual strips has demonstrated that the entire thickness depth (5 mm in this case) of a domestic window has been filled up with thermoelectric materials using physical vapor deposition (PVD), that could not be achieved otherwise, due to physical limits of vertical deposition by PVD, electrochemical deposition, etc
We have demonstrated thermoelectric system-embedded Plexiglas subset for power generation using naturally occurring temperature gradient between outdoor high temperature and indoor room ambient environment
Summary
Thermoelectric generation has recently emerged as a significant candidate in the area of renewable and sustainable energy harvesting. Using physical vapor deposition process, we experimentally verify this concept by embedding bismuth telluride and antimony telluride through the 5 mm Plexiglas to demonstrate 10 nW of thermopower generation with a temperature gradient of 21 °C. We report generation of thermoelectricity due to temperature gradient created across the two faces of a Plexiglas interface slide with specialized TE materials filled through the interface employing a novel deposition technique.
