Scientists have found a promising new alternative solar cell material that may lead to more efficient and cheaper solar panels. Perovskite is relatively easy to process and, therefore, cheaper to manufacture, but also has an efficiency of 22 per cent, close to currently used silicon-based cells’ 25 per cent. Silicon is very labour-intensive and requires very high temperatures to process. But with alternative cells there is inefficiency in capturing the energy from Sun. Dominance of commercial and research investment in silicon has made it difficult to convince researchers and commercial developers to adopt new technology.
