The best tilt angle to improve PV system performance on low-cost buildings
Researchers have demonstrated that the theoretical optimal tilt for rooftop solar energy production in low-cost buildings in Nigeria is approximately 5.67°. Their modeling suggests to adopt south-facing roofs for PV generation in the Global South.
SERIS achieves world record efficiency of 26.7% for perovskite-organic tandem solar cell
The tandem device is based on a bottom organic cell that can achieve a remarkable power conversion efficiency of 17.9% and a high short-circuit current density of 28.60 mA cm2. Furthermore, it uses a top perovskite solar cell with an open-circuit voltage of 1.37 V and a fill factor of 85.5%.
