摘　　要：染料敏化太阳能电池(dye-sensitized solar cells,DSSC)是一种新型的光电化学太阳能电池,制作工艺简单,成本低,具有较好的应用前景。以钝顶螺旋藻和莱茵衣藻萃取物为原料,衍生制备叶绿酸敏化剂,作为DSSC的光敏剂,发现在叶绿酸敏化剂溶液中适量保留天然微藻磷脂类共吸附剂有助于改善叶绿酸的敏化性能,提高电池的光电转化效率,所制备的钝顶螺旋藻和莱茵衣藻叶绿酸敏化剂DSSC的光电转化效率分别达到了4.28%和4.40%。Dye-sensitized solar cell（DSSC） is a new type of photoelectrochemical solar cell,which possesses advantages of a simple manufacturing process,low cost,and good application prospect. Using Spirulina platensis and Chlamydomonas reinhardtii extracts as raw materials,we prepared chlorophyllin-sensitizer as a photosensitizer for DSSC by derivation. We found that retention of natural microalgae phospholipids coadsorbent in the chlorophyllin-sensitizer solution was helpful to improve the sensitization properties of chlorophyllin,and improve the photoelectric conversion efficiency of cells. The photoelectric conversion efficiency of DSSC sensitized by Spirulina platensis and Chlamydomonas reinhardtii chlorophyllin-sensitizers could reach 4. 28% and 4. 40%,respectively.
