Abstract

A photovoltaic cell substrate and a photovoltaic cell including the same are disclosed. The photovoltaic cell substrate includes a transparent substrate and a transparent conductive film formed over the transparent substrate. The transparent conductive film includes a zinc oxide thin film layer doped with a dopant, and both a (0002) growth plane and a (101 1) growth plane are present in the zinc oxide thin film layer according to X-Ray Diffraction (XRD) data.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2010-0015150 filed on February 19, 2010, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a photovoltaic cell substrate and a photovoltaic cell comprising said photovoltaic cell substrate. Background technique [0004] Photovoltaic cells are key components in solar power generation, which converts solar energy directly into electricity. Photovoltaic cells are used in various fields including electrical and electronic devices, power supply for homes and buildings, and industrial power generation. The most important basic structure of a photovoltaic cell is a p-n junction diode. According to the material used in the light-absorbing layer, photovoltaic cells can be divided into silicon photovoltaic cells using silicon as the light-absorbing layer; copper indi...
