A novel dithienogermole‐containing a small‐molecule donor termed p ‐DTG(FBTTh 2 ) 2 is synthesized and characterized, and its optical, thermal, and electrical properties are found to be comparable to its silicon analogue ( p ‐DTS(FBTTh 2 ) 2 ). Solar cells based on an active layer of p ‐DTG(FBTTh 2 ) 2 and the fullerene PC 70 BM exhibit a power conversion efficiency of up to 6.9%, indicating that p ‐DTG(FBTTh 2 ) 2 is an excellent small‐molecule donor.
