Abstract

In this work, we present a cost‐effective, scalable approach for fabricating thermoelectric (TE) generators using p‐type tin selenide (SnSe) bonded in a cement matrix via a slurry mold casting technique. Traditional methods for manufacturing SnSe‐based TE materials are energy‐intensive and economica...
