A transparent conductive oxide (TCO) film coated metal microstructures as solar selective absorbers for high-temperature usage exceeding 700°C is introduced. Steep absorption cutoff property and low-emittance at infrared range owing to TCO characteristic can be seen, whereas high-absorptance explained by interaction of incident light and microstructures of which size is submicron is appeared. Honeycomb array cylindrical microcavity of which an absorptance peak appeared at around 0.8 μm was fabricated on a tungsten (W) surface with interference lithography technique. The fabricated sample consist of 1.0 μm indium tin oxide film and W microstructure showed solar absorptance αs = 0.83, hemispherical emittance ϵht = 0.16 assuming the absorber temperature at 700°C, and performance factor η= 0.76. Short duration thermal stability was confirmed at 700°C for 2 h in vacuum condition.
