The power generation of the aerogel-covered STEG dropped by only 3.0%. The maximum power generation of the aerogel-covered STEG was 54% and 71% higher than those of the glass-covered and uncovered STEGs, respectively. These results show that aerogel windows offer greater advantages than glass for STEGs in open environments.
