Cellulose-based nanomaterials are used in a variety of potential applications, particularly in green electronics and optoelectronic devices, due to their sustainability, low cost and the ease of chemical functionalization. For recycling and prefabrications of cellulose-based solar cells, we propose the fabrication of green, fully sprayed solar cells based. The electrode material using conductive inks laminated with cellulose is easy to fabricate in large-area solutions. Preferably chlorine-free solvents are used in the active layer, and solvent engineering and post-treatment are used to control the morphology and aggregation to achieve high performance and environmental recyclability. The solar cells are planned to be recycled using the most environmentally friendly physical and chemical methods. The solar cell materials should be recycled to the maximum extent possible, and the recycled materials are then used to refabricate the solar cells and evaluate them in terms of morphology and efficiency.
