Abstract：

In　this　paper,　smart　photovoltaic　(SPV)　devices,　integrating　both　functions　of　solar　cells　and　smart　windows,　was　fabricated　based　on　dye-sensitized　solar　cells　using　photochromic　spiropyran　derivatives　SIBT　as　photosensitizers.　SPV　devices　have　self-regulated　power　conversion　efficiency　(PCE)　and　light　transmission　responding　to　the　incident　spectra　due　to　the　photoisomerization　of　SIBT.　SIBT　isomerize　from　closed-ring　form　to　open-ring　form　under　UV　illumination,　accompanied　with　enhanced　visible　light　absorption　and　electron　delocalization.　Therefore,　increased　PCE　and　absorption　in　SPV　devices　were　observed　under　UV　treatment　and　the　devices　can　be　restored　gradually　to　the　initial　status　when　kept　in　dark.　The　SPV　devices　have　self-regulation　of　PCE　and　sunlight　transmission　responding　to　the　changing　sun　spectra　in　different　times　of　a　day,　providing　a　proper　energy　usage　and　a　better　sun-shading.　©　2015　Author(s).
