Organic solar cells could power homes for decades with new degradation-resistant design.
Understanding how organic solar cells degrade is important for making them more stable. Researchers studied how different parts of the solar cell affect its stability under light, heat, and storage. They found that UV light can make the solar cell lose some of its power. The type of materials used in the cell can also affect how it degrades. Heating the solar cell can cause the silver electrode to roughen, which can make the cell fail. Adding a thin metal-oxide layer can prevent this. Lastly, a new material called P3HT-Si can improve the efficiency of the solar cell by reducing leakage current.
