Abstract

The present invention relates to a method for manufacturing a carbon electrode-based solar cell comprising a perovskite thin film surface-treated through polishing, and a carbon electrode-based solar cell manufactured by the method. According to the present invention, the surface of the perovskite thin film can be smoothed through polishing. Accordingly, the performance and stability of the solar cell are improved by inducing the formation of an effective interface with a hole transport material due to reduced surface roughness. Additionally, the present invention is effective for a carbon electrode-based solar cell, and exhibits improved thermal stability due to the non-use of a metal electrode that is unstable at high temperatures.

Abstract

The present invention relates to a method for manufacturing a carbon electrode-based device and a carbon electrode-based device manufactured by the method. According to the present invention, introducing a solvent treatment process using a fluorosolvent induces densification of a carbon electrode without damaging a hole transport layer or perovskite, and thus an effective interface can be formed between the carbon electrode and the hole transport layer. Accordingly, reduction in porosity results in improved conductivity of the carbon electrode, and interface optimization leads to enhanced device performance. In addition, the present invention is suitable for large-area applications at low cost and is compatible with various processes, such as lamination and hot pressing, which can be applied to carbon electrodes.
