当代的 nanostructured 为在太阳能电池的使用的透明电极要求高发射度和高电导率，与高方面比率支配 nanostructures。光薄雾是在为被 nanostructures 的几何学也决定的太阳能电池的透明电极的一个同等地重要的还未学得的参数填写电极。在这个工作，在可见光谱的光薄雾价值上的银 nanowire 直径的效果用与小直径(60 nm ) 或大直径(150 nm ) 由电线组成的电影被调查。有限差别时间领域(FDTD ) 模拟和试验性的发射度数据证实更高根据优点的当前的数字的意见执行透明进行的电极(TCE ) 电影的那种更小的直径 nanowires 形式。当为每部电影在经常的发射度和电导率附近维持时，然而，电影与更大的直径银 nanowires 创作了，这试验性地被观察与更小的直径比电影有一个更高的薄雾因素。这与同样大、小的直径为单个 nanowires 证实薄雾因素的 FDTD 模拟。这是为被模仿了或试验性地测量了的 Ag NW 的薄雾性质的第一个记录，并且也，第一证实为 TCE 的优点的当前的数字是不够的在太阳能电池设备评估他们的表演。
Contemporary nanostructured transparent electrodes for use in solar cells require high transmittance and high conductivity, dictating nanostructures with high aspect ratios. Optical haze is an equally important yet unstudied parameter in transparent electrodes for solar cells that is also determined by the geometry of the nanostructures that compose the electrode. In this work, the effect of the silver nanowire diameter on the optical haze values in the visible spectrum was investigated using films composed of wires with either small diameters （N60 nm） or large diameters （~150 nm）. Finite difference time domain （FDTD） simulations and experimental transmittance data confirm that smaller diameter nanowires form higher performing transparent conducting electrode （TCE） films according to the current figure of merit. While maintaining near constant transmittance and conductivity for each film, however, it was observed experimentally that films composed of silver nanowires with larger diameters have a higher haze factor than films with smaller diameters. This confirms the FDTD simulations of the haze factor for single nanowires with similarly large and small diameters. This is the first record of haze properties for Ag NWs that have been simulated or experimentally measured, and also the first evidence that the current figure of merit for TCEs is insufficient to evaluate their performance in solar cell devices.
