Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) have improved an innovative solar-energy device to be about 100 times more efficient than its previous design in converting the sun’s light and heat into electricity.
Additionally, the growing importance of solar energy storage is underscored by the fluctuating nature of solar energy production and the variability in energy demand. Here, we introduce a possible PV-based hybrid technology that seeks to mitigate these challenges.
The hybrid system demonstrated a solar utilization efficiency of 14.9%, underscoring its potential to achieve even greater efficiencies in forthcoming advanced hybrid PV solar energy systems.
The solar thermal energy storage efficiency η experiment of the MOST system has been determined to reach up to 2.3%, representing the highest recorded efficiency to date. 34 Additionally, the inclusion of the MOST system as a non-heating temperature stabilizer with optical filter effect can further enhance the efficiency of the PV cell.
Future research is aimed at making the device up to an additional 10 times more efficient by developing new coatings or surface treatments that will preserve the atomic arrangement of the second layer’s outer surface at the high temperatures it will encounter in the concentrating solar power plant.
