CMU scientists invent low-cost and efficient carbon electrode for thin perovskite solar cells, paving way for commercialisation
“This carbon electrode is made from conductive carbon paste using the ethanol solvent interlacing process at room temperature to produce a perovskite solar cell that has great efficiency and stability.” The process is simple and low-cost but yields great results, capable of replacing an expensive film preparation.
This type of carbon film is moisture-resistant and flexible, making it suitable for use in Thailand. On top of that, this process opens up the possibility of the commercialisation of flexible solar cells in the future.
When used as an electrode in the perovskite solar cell, this carbon film had a maximum efficiency of 12.1%, while also showing long-term stability of 80% over 1,000 hours without encapsulation.
