In combination with a solvent-free ionic liquid electrolyte, a similar to 7% cell made with this sensitizer shows all excellent stability measured under thermal and light-soaking dual stress. For the first time a 4.8% efficiency is reached for all-solid-state dye-sensitized solar cells based oil all organic dye.Charge-TransportHigh-EfficiencyRecombinationPhotovoltageEnhanceAcidtext::journal::journal article::research article
