Summary:
- This article describes a new method for creating high-efficiency solar cells using a material called perovskite. Perovskite solar cells have the potential to be much cheaper and more efficient than traditional silicon-based solar cells.
- The researchers developed a technique called "single-crystal perovskite" that allows for the creation of large, high-quality perovskite crystals. This leads to solar cells with record-breaking efficiency of over 25%.
- The improved perovskite solar cells could make renewable energy more accessible and affordable, helping to reduce our reliance on fossil fuels and combat climate change.
