Longi achieves 34.6% efficiency for two-terminal tandem perovskite solar cell prototype
In a paper published in nature, the Chinese module maker explained that the 33.9%-efficient tandem device it unveiled in December 2023 is based on a bilayer intertwined passivation strategy that combines efficient electron extraction with further suppression of nonradiative recombination. It also revealed that its two-terminal tandem prototype devices achieved an efficiency of 34.6%.
Optimizing bifacial solar panels for floating PV applications in tropical freshwater
New research from India shows how bifacial solar modules should be deployed to achieve strong performance in floating PV projects planned on tropical freshwater. Their experimental setup demonstrated that higher efficiency gains are achievable by gauging panel height, water depth, and tilt angle.
