Figure 3. Several solution processible conjugated polymers and a fullerene derivative used in organic solar cells. Chemical structures and abbreviations of some conjugated organic molecules. From left: poly (acetylene) PA, poly(para-phenylene-vinylene) PPV, a substituted PPV (MDMO-PPV), poly(3-hexyl thiophene) P3HT, and a C60 derivative In each compound one can identify a sequence of alternating single and double bonds
