Paving the way for lead-free perovskites

Scientists in Germany and China have developed an additive which greatly improved the performance of a tin-based perovskite solar cell. Cells fabricated with the additive reached 9.1% efficiency, and the researchers say their work opens up many new possibilities to improve the performance of lead-free perovskites.The buzz around perovskite solar cells, often called "the next generation" of solar PV technology, comes with a caveat. All of their impressive efficiency achievements so far have involved lead, a highly toxic material that remains a concern for regulators, despite assurances from those ...
