摘要：

By identifying the right combination of laser parameters, in particular the integrated laser fluence Phi, we fabricated dye solar cells (DSCs) with UV laser-sintered TiO(2) films exhibiting a power conversion efficiency eta=5.2%, the highest reported for laser-sintered devices. eta is dramatically affected by Phi and a clear trend is reported. Significantly, DSCs fabricated by raster scanning the laser beam to sinter the TiO(2) films are made as efficient as those with oven-sintered ones. These results, confirmed on three batches of cells, demonstrate the remarkable potential (noncontact, local, low cost, rapid, selective, and scalable) of scanning laser processing applied to DSC technology.
