Some of that sunlight is currently converted into electricity by arrays of solar panels: by the end of 2023, these panels covered almost 10,000 square kilometres of Earth’s surface, producing some 1,600 terawatt-hours of electricity, about 6% of that generated worldwide. The amount of installed solar-capacity has been doubling roughly every three years. This is happening as the silicon-based solar cells used in the panels have been getting cheaper with intense competition among firms in China, which with state support have come to dominate the industry. At the same time, researchers have
