Bifacial Perovskite Solar Cells Point to Higher Efficiency
A bifacial perovskite solar cell, which allows sunlight to reach both sides of the device, holds the potential to produce higher energy yields at lower overall costs, according to scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).
The dual nature of a bifacial solar cell enables the capture of direct sunlight on the front and the capture of reflected sunlight on the back, allowing this type of device to outperform its monofacial counterparts.
“This perovskite cell can operate very effectively from either side,” said Kai Zhu, a senior scientist in the Chemistry and Nanoscience Center at NREL and lead author of a new paper published in the journal Joule: “Highly efficient bifacial single-junction perovskite solar cells.” His co-authors from NREL...
