Organic semiconductors are materials made from carbon-based compounds that can conduct electricity. Unlike traditional semiconductors, which are typically made from silicon, organic semiconductors are flexible and lightweight. They are used in various applications, including organic light-emitting diodes (OLEDs), organic solar cells, and organic field-effect transistors (OFETs). These materials can be processed at lower temperatures and can be printed onto surfaces, making them suitable for innovative electronic devices. Their unique properties allow for the development of flexible displays and wearable technology, contributing to advancements in the field of electronics and renewable energy.
