In a quest to improve the efficiency of tandem solar cells, researchers at North Carolina State University have harnessed the power of robotics to expedite the discovery of the ideal materials. Tandem solar cells, which combine silicon with perovskite materials, have achieved record-breaking 33 percent efficiency but still fall short of their theoretical limit of approximately 45 percent due to degradation under sunlight.
The challenge lies in finding the perfect combination of materials that efficiently capture sunlight and remain stable at normal temperatures. Perovskites, with their distinctive rhombus-in-a-cube crystal structure, hold promise for tandem solar cells. However, predicting the properties of different chemical compositions is a complex and costly task.
