A series of novel organic dyes containing a benzopyran ring as a Ïâbridge have been designed and applied in dye-sensitized solar cells (DSSCs). This series of dyes show the excellent DSSCs' performance, due to their efficient light-to-photocurrent conversion in the region from 380 nm to 600 nm, with the highest IPCE values exceeding 90%. Through modification of the donor units, an efficiency as high as 7.5% has been achieved under standard light illumination (AM 1.5G, 100 mW cmâ2) by the dye CC103.
我们设计了一系列含有苯并
吡喃环作为Ïâ桥的新型有机
染料,并将其应用于
染料敏化太阳能电池(DSSC)。这一系列
染料在 380 纳米到 600 纳米的区域内具有高效的光-光电流转换能力,最高 IPCE 值超过 90%,因而显示出卓越的 DSSC 性能。通过修饰供体单元,
染料 CC103 在标准光照(
AM 1.5G,100 mW cmâ2)下的效率高达 7.5%。
