Document Type and Number:
WIPO Patent Application WO/2012/014572
Kind Code:
A1
Abstract:
Disclosed are a transparent electrode, which contains a zinc oxide layer wherein initial characteristics and resistance to damp after prolonged use coexist, and a thin film solar cell provided with said electrode. The transparent electrode contains a transparent conductive layer comprised primarily of zinc oxide. The following characteristics are preferable in the transparent conductive layer: an uneven surface; a carrier concentration of 9 x 1019 cm-3 or less; liquid crystals having a preferred orientation of (110); the ratio I (110)/ I (002) of the (110) peak intensity to the (002) peak intensity using X-ray diffraction being at least 50; and (110) oriented liquid crystal elements having a size of 23-50 nm in the planar direction parallel to the substrate and 30-60 nm in the planar direction perpendicular to the substrate.
