Two water-soluble regioregular poly(3-alkylthiophene)s, incorporating aminic groups at the end of the side chains, have been synthesized using a post-polymerization functionalization procedure on a ω-bromine substituted polyalkylthiophene. The high solubility of the obtained polymers in water allowed for the preparation of “green” bulk heterojunction solar cells which reached a power conversion efficiency of 4.85% when PC₆₁BM was used as electron-acceptor material. Improved optical absorption and photocurrent have been obtained by interposing a layer of Ag nanoparticles between the buffer and the photoactive layer, leading to a final power conversion efficiency of 5.51%.

已经在ω-溴取代的聚烷基噻吩上使用后聚合官能化方法合成了两个在侧链末端结合有氨基的水溶性区域规则的聚（3-烷基噻吩）。获得的聚合物在水中的高溶解度允许制备“绿色”本体异质结太阳能电池，当将PC ₆₁ BM用作电子受体材料时，其功率转换效率达到4.85％。通过在缓冲层和光敏层之间插入一层银纳米颗粒，可以提高光吸收和光电流，最终功率转换效率为5.51％。
