High-Efficiency Carbon Electrode Perovskite Solar Cells via CIP

• Revolutionary lamination technique, CIP, creates high-efficiency carbon electrode-based perovskite solar cells to rival gold electrodes. A game-changer in renewable energy technology.

Researchers from Monash University and CSIRO Manufacturing have developed a lamination technique called cold isostatic pressing (CIP) to create carbon electrode-based perovskite solar cells with an efficiency of 20.8%. The new electrode made of carbon and silver can compete with gold-carbon electrodes in terms of efficiency and stability. The team aimed to address the challenge of optimizing the interface between the hole transport layer (HTL) and the carbon electrode without damaging the underlying functional layers.

Cold isostatic pressing (CIP) applies high mechanical pressure to form a seamless physical connection between the HTL and carbon film without heat or additional morphology modifications. The resulting solar cell achieved a power conversion efficiency of 20.8%, comparable to devices with more expensive gold electrodes. The researchers believe these findings pave the way for developing low-cost, efficient, and reliable perovskite solar cells.
