Abstract
With the recent intensification of environmental pollution, interest in eco-friendly energy sources is increasing. AAmong these, perovskite solar cells, a next-generation solar cell, are frequently reported to exhibit high device efficiencies. The performance of perovskite solar cells is strongly influenced by the properties of each functional layer within the device. In particular, the hole transport layer (HTL) is one of the key components affecting device efficiency and stability because of its role in hole extraction and transport. In this study, we aimed to fabricate a polymer thin film using chemical vapor deposition (CVD) for its potential application as an HTL. CVD is a dry deposition process that enables the formation of uniform and ultra-thin films. To overcome pinhole formation that may occur during conventional solution processing, we utilized the advantages of CVD and investigated poly(p-phenylene vinylene) (PPV) as a potential HTL material. Although PPV has primarily been used as an emissive layer in light-emitting diodes, it also exhibits hole-transporting properties. Therefore, this study focused on confirming the formation of PPV polymer thin films through the CVD process and evaluating whether the films could be uniformly deposited at an ultra-thin thickness (~10nm). The results of this work may serve as a fundamental basis for future studies investigating the applicability of CVD-deposited PPV thin films as an HTL in perovskite solar cells.
