It is found that transparent conducting films composed of silver nanowires with large diameters exhibit greater optical haze than films with smaller diameters, even when both films exhibit nearly equal transparency and sheet resistance. This contradicts the contemporary figure of merit because films with the greater haze are better for solar cell applications.

Address correspondence to Qing Peng,; Yadong Li,

Six LiFePO4 nanocrystals with different size and shape have been successfully synthesized in ethylene glycol by controlling the sequence of addition and ratio of the reagents. The most promising LiFePO4 nanocrystals have either predominantly {010} face exposure or high specific area with little iron(II) oxidation.

Graphene mesh electrodes (GMEs) have been prepared by the standard industrial photolithography and O2 plasma etching process using graphene solutions. Organic photovoltaic devices based on the GMEs with poly-(3-hexylthiophene)/phenyl-C61-butyric acid methyl ester (P3HT/PC61BM) as the active layer have been fabricated and exhibit a power conversion efficiency of 2.04%, the highest efficiency for solution-processed graphene transparent electrode- based solar cells reported to date.

We have examined in situ the local oxidation of graphene-coated materials in air at room temperature for long periods of time. The onset of oxidation takes place at the graphene domain boundaries, and it propagates to the surrounding areas, which dramatically reduces the morphological, electrical, mechanical, and frictional performance of graphene-based devices.

With proper Al2O3 passivation, carbon nanotube n-type FETs display reliable performance in air. Passivation layers reduce gate hysteresis to less than 0.1 V, and key device performance merits remain unchanged even after exposure to air for 146 days. Power-on tests, which evaluate the potential for practical applications, prove that the devices can still work in air for at least 10 h and generate perfect output characteristics afterwards.
