Scientists from Nanyang Technological University (NTU) in Singapore have developed an environmentally friendly perovskite solar cell that could replace traditional silicon solar cells. Perovskite solar cells are more cost-effective and have higher efficiency, but commercial production has not yet been achieved due to concerns about their stability and the small amount of lead they contain. The researchers have found a way to replace the lead-containing capping layer with non-toxic metals, which could make perovskite solar cells more viable for widespread use. The team is now working on fabricating full-sized solar cells using this method.
