Bifacial perovskite solar can achieve bifaciality of 90% when tilted at 20 degrees

New research from India has shown that bifacial perovskite solar cells can achieve a 2% higher power conversion efficiency with a tilt angle of 20 degrees. The scientists also developed a bifacial perovskite solar cell for applications in both tandem or single-junction PV devices. Researchers from the Indian Institute Of Technology Bombay have conducted a quantitative analysis of optimal values for albedo and tilt angle in bifacial perovskite solar cells and have found that enhancing the rear-side albedo to 0. 5 and using a tilt angle of 20 degrees results in the highest efficiency levels. "Our ...
