In polymer solar cell research, the term low band gap polymer (LBG) is loosely defined and changes with time. Polymers with smaller band gaps than P3HT are typically called LBG polymers now, but even P3HT was called LBG when MEH-PPV is the champion. In tandem application, a polymer with a band gap above 1.7
