Abstract: Vertical standing, thin graphitic nano-partitions were fabricated on quartz and silicon substrates using a reactive plasma sputtering system. These nano-sized partitions act as light reflectors, enhancing the solar absorption of omni-directional incident light. The structure of nano-partitions doubles the output power of the solar cell when illuminated from a 30° to 150° angle of incidence. Such nano-partitions also enhance solar efficiency when reflected light is used to produce more photon absorption. Measurement of reflectance has shown a minimum of 0.49% at a wavelength of 580 nm when nano-partitions are used. The average reflectance of the entire visible regime is 0.85%, which is equivalent to the conventional multi-layer anti-reflection coatings. We also found that this nano-partition system has superior anti-reflection efficiency in a UV regime. This 3D anti-reflection structure provides a promising route to the fabrication of high-efficiency solar cells.
