摘要
Photovoltaics with dye-sensitized solar cells have been recognized as being promising for the utilization of sunlight to produce electricity and‘solar chemicals’.One of the remaining unsolved challenges is the development of an affordable,robust dye that has a panchromatic light harvesting range and efficiently provides separated charges for the desired photochemistry.The most commonly employed molecular photosensitizers include the noble metal-based ruthenium and iridium complexes,synthetically challenging porphyrin derivatives,and expensive,functionalized polypyridine compounds.Here,we describe the development of Cu(I)dyes supported by bis(arylimino)acenaphthene(Ar-BIAN)ligands,which can be synthesized in fewer than three steps from affordable,commercially available reagents.
