The technology has the potential to outperform its monofacial counterparts.

According to scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), a bifacial perovskite solar cell holds the potential to produce higher energy yields at lower overall costs.

The bifacial solar cell captures direct sunlight on the front and reflected sunlight on the back. As a result, this type of device can outperform its monofacial counterparts, according to the new study.

“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.

Bifacial photovoltaics (PV) harvest solar irradiance from both their front and rear surfaces, boosting energy conversion efficiency to maximize their electrical power production. However, it’s important to note that bifacial single-junction perovskite solar cells are still far behind that of their monofacial counterparts in terms of performance. It is challenging to achieve both high bifaciality and high front-side illumination efficiency at the same time.
