摘要

We report a new (to the best of our knowledge) transparent conductive oxide (TCO) layer with a monolayer of closed-pack Al-doped ZnO (AZO) spheres partly embedded in an AZO thin film. The average transmittance and haze ratio in the wavelength range of 380-800nm achieves 65percent and 55percent, respectively, when AZO spheres with a diameter of 500 nm are embedded in a thickness of 240 nm AZO thin films. The a-Si thin-film solar cell with a regular p-i-n TCO structure is demonstrated. Under air mass 1.5 global illumination, conversion efficiencies of 5.6percent, a fill factor of 0.55, V_(oc) of 0.81 V, and a J_(sc) of 2.44 mA/cm~(2) are obtained. The Letter helps us to open up potential applications of a new TCO in advanced solar cells and light-emitting diodes.
