A simple structured solar selective absorber for application in thermoelectric energy harvesters

Abstract

This study focuses on green energy harvesting that aims to supply electricity from a different energy source: solar thermoelectric, which is present in the environment without grid connection or utilization of batteries. The concept of using solar selective absorbers and heat sinks is introduced to create temperature differences, which are then converted into electrical energy via the use of a thermoelectric power generator. The solar selective absorber used in this study is a light-absorbing material, and its voltage generation is then compared to a blackbody.
