New fabrication method for perovskite solar cells promises to break the efficiency limit

The direct solar-to-electricity conversion enabled by solar cells can play pivotal role in our future energy supply. Increasing the cost-effectiveness of solar cells is essential to accelerate the upcoming terawatt-scale solar industry. However, this is complicated as conventional crystalline silicon is already approaching its efficiency limit of 33 percent. One viable strategy is to fabricate solar cells that combine various light-absorbing materials that can capture a larger portion of sunlight, which could ultimately raise the efficiency to 68 percent. Ph.D. candidate Junke Wang has developed a new strategy to fabricate solar cells based on novel perovskite semiconductors that promise efficiencies above 35 percent. Wang successfully defended his thesis on December 10th.
