Organic Solar Cell Materials

A common thiophene-based donor material is poly(3-hexylthiophene), or P3HT. It is soluble in several organic solvents, which makes it compatible with low-cost solution processing. Another donor material is poly(3,3///-didodecyl quaterthiophene), or PQT-12. Their molec­ular structures are shown in Figure 6.34. The optical absorption spectra of these compounds (Figure 6.35) show that their absorption bands are […]
