英文摘要	In this paper, a novel kind of functional nh2-rich silica nanoparticle (a-sio2) as an electrolyte additive is reported, which is employed to assemble high-efficiency quasi-solid-state dye-sensitized solar cells (dscs) and quantum dot sensitized solar cells (qdscs), while the additional solidifying character of asio(2) makes it superior to the common additives. it is found that the a-sio2 nanoparticle as an additive for ionic-liquid electrolyte can significantly improve the photovoltaic performance of quasi-solid-state dscs, especially the open-circuit photovoltage (voc) and fill factor (ff) through ( 1) negatively shifting the tio2 conduction band (cb) edge, (2) effectively facilitating the ions transport and (3) remarkably inhibiting the charge recombination. notably, dsc fabricated using the a-sio2 based ionic-liquid gel electrolytes achieves a power conversion efficiency (pce) of 7.30% under 1 sun illumination (am 1.5 g, 100 mw cm(-2)), which is higher than that of dsc with the ionic-liquid electrolyte employing n-methylbenzimidazole (nmbi) and guanidinium thiocyanate (guncs) as additives (pce = 6.23%). moreover, the a-sio2 additive is of the universality in organic electrolytes for dscs and polysulfide electrolytes for qdscs. the pce of cds/cdse co-sensitized qdscs using a- sio2 additives is improved by 34.9% due to the enhancement of short-circuit current density (jsc) and voc, resulting in a champion pce of 7.11%, which is one of the best results for cds/cdse co-sensitized qdscs.
