  "textContent": "Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries and are contributing to the reduction of greenhouse gas emissions on Earth. While most of the solar cells on the market today are based on silicon, energy engineers have been exploring the potential of other photovoltaic materials, including a class of materials known as perovskites.",
