透明的，导电的，和石墨烯薄膜，作为一种替代普遍采用的金属氧化物窗口电极的固态染料敏化太阳能电池，被证明。这些石墨烯膜由剥离的氧化石墨制成，然后进行热还原。所得薄膜在1000-3000 nm范围内具有550 S/cm的高电导率和大于70%的透明度。此外，它们显示出高的化学和热稳定性以及具有可调润湿性的超光滑表面。
Transparent, conductive, and ultrathin graphene films, as an alternative to the ubiquitously employed metal oxides window electrodes for solid-state dye-sensitized solar cells, are demonstrated. These graphene films are fabricated from exfoliated graphite oxide, followed by thermal reduction. The obtained films exhibit a high conductivity of 550 S/cm and a transparency of more than 70% over 1000-3000 nm. Furthermore, they show high chemical and thermal stabilities as well as an ultrasmooth surface with tunable wettability.
