Abstract Indium-based transparent conductive thin films are used in various opto-electric devices. In particular, the In2O3:ZnO (IZO) thin film exhibits a high electrical conductivity and high transmittance despite deposition at a low temperature of less than 100℃. IZO thin film has the advantage of being free from damage caused by heat even compared to the existing ITO thin film. In this study, we investigated the requirements for use of TCO films in silicon-based solar cells and the best alternative TCO materials to improve their efficiency. Moreover, we discussed the current status of high-efficiency solar cells using low-temperature TCO films
