摘要

Dye-sensitized solar cells (DSSCs) have a promising future because of their low production cost,easy fabrication and relatively high solar energy conversion efficiency.In the past two decades,increasing interests have been focused on the improvement of cell efficiencies.Thus,many efficient sensitizers with donor-π-acceptor frameworks have been successfully developed.In this respect,porphyrins have been widely investigated because of their strong Soret bands (400-450 nm) and moderate Q bands (550-650 nm).
