STATUS AND PROGRESS IN DYE AND PEROVSKITE SENSITIZED SOLAR CELLS

摘要

Solar cells using dyes or perovskites as light harvesters supported by mesoscopic oxide films have emerged as credible contenders to conventional p-n junction photovoltaic devices. Separating light absorption from charge carrier transport, dye sensitized mesoscopic solar cells (DSCs) were the first to use a three-dimensional nanocrystalline junction for solar electricity production. The profound knowledge developed during the last 2 decades in DSC technology enabled the stunning rise of perovskite solar cells, and the certified power conversion efficiency (PCE) of perovskite solar cells has reached 17.9% under AM 1.5G 100 mW cm~(-2) illumination. For the dye sensitized solar cells under ambient and indoor light conditions PCE values up to 26 % have been reached; outperforming silicon based solar cells by a large margin. These features along with excellent long-term stability have fostered first commercial applications, the industrial production of DSC's attaining presently the MW/year scale.
