Editorial Note On Organic SemiconductorsAuthor(s): Kate Wilson
Solution-processed semiconductor materials have intriguing optical and electrical characteristics and have found use in solar energy harvesting, display technologies, and bioelectronics. Organic Semiconductors (OSC) have sparked considerable interest in this context due to their incorporation into a variety of optoelectronic devices such as Organic Light-Emitting Diodes (OLED), Organic Photovoltaic (OPV), Organic Field-Effect Transistors (OFET), and emerging technologies such as wearable electronics. The advantages of OSCs for such applications include cheap synthetic cost, light weight, and great synthesis scalability, as well as simple deposition processes for printed electronics, big area, and flexible solar cells. OLEDs are the most commercialized of the aforementioned technologies, appearing in items such as smartphones and screens. Power Conversion Efficiencies (PCEs) of more than 18% have recently been recorded in single active layer devices, indicating that OPV technology is becoming more practical. Furthermore, due to the adjustable energy levels of organic materials to match the indoor spectrum, Indoor OPV (IPOV) technology is gaining traction.
