Solar Cell Efficiency Rises By 30% Through Singlet Fission

Posted on July 15, 2014 by Ritesh Pothan

Scientists were pretty excited when they discovered you could convert light energy directly into electricity by capturing photons in semiconductors, exciting them into “excitons” (bound electron with negative charge and hole with positive), and capturing the resultant current through electrodes. … Continue reading →
