Larger doping molecule enhance performance of organic semiconductor

Organic semiconductors have emerged as a promising alternative to traditional inorganic semiconductors like silicon, offering flexibility, low-cost manufacturing, and the potential for innovative applications such as printed electronics, flexible displays, and painted solar photovoltaic (PV) panels. Unlike silicon, which requires energy-intensive and complex processes to produce crystalline structures, organic semiconductors can be processed at room temperature using simple techniques like inkjet printing or spin-coating. This makes them ideal for applications such as e-tags for inventory management, wearable electronics, and large-area optoelectronic devices. However, a persistent challenge has been their relatively low electrical conductivity compared to inorganic counterparts. Recent advancements in doping strategies, particularly the use of larger doping molecules, are addressing this limitation, significantly enhancing the performance of organic semiconductors. This article explores these developments, building on foundational research from 2015 and incorporating the latest findings from 2024 and 2025.
