A new donor/acceptor (D–A) spiro dye (SCPDT1) featuring two bithiophene units, connected through an sp3-hybridized carbon atom, was prepared by a multistep synthetic sequence involving the convenient assembly of the spiro system under mild catalytic conditions. The photocurrent spectrum of dye-sensitized solar cells incorporating SCPDT1 covers the spectral region ranging from 350 to 700 nm and reaches
一种新的供体/受体(DA)螺旋染料(SCPDT1),具有两个通过SP 3-杂化碳原子连接的联噻吩单元,是通过多步合成序列制备的,该过程涉及在温和的催化条件下方便地组装螺旋系统。装有SCPDT1的染料敏化太阳能电池的光电流光谱覆盖350至700 nm的光谱范围,并在420-560 nm范围内达到约80%的最大最大值。获得了高达6.02%的功率转换效率。
