Researchers endeavoring for a clean energy resource have focused on a semiconducting material called graphitic carbon nitride (g-C3N4). The unique property of this material is being environmentally benign due to its metal-free nature, and high solubility in water. Moreover, the earth-abundance of carbon and nitrogen enables easy synthesis at low costs. The astonishing optoelectronic properties, high stability, and absorption in UV-visible region with band-gap energy of 2.7eV render g-C3N4 a prime center for the extensive applications such as solar energy utilization. Fabrication of homogeneous g-C3N4 thin films with tailored thickness and morphology is important to develop novel applications. However, the material deposition to achieve homogeneous thin films is still challenging, rendering information about the bulk material properties essential for device application largely unknown to date. In this work, the low waste and scalable slot-die coating method is fine-tuned to get uniform and high-quality films with good adhesion onto the substrates. The final optimized thin-film properties are studied in terms of spectroscopic, morphological and structural characterization methods.
