This study investigates bulk heterojunction photoactive layers constituted of selectively oxidized graphene (SOG), molybdenum disulfide (MoS), and poly 3-hexyl thiophene (P3HT) deposited by spray coating. The functionalization of these 2D materials was confirmed by X-ray photoelectron spectroscopy, attenuated total reflection Fourier-transform infrared spectroscopy, and Raman spectroscopy. The results show that functionalized 2D materials significantly modify the surface morphology and roughness of the photoactive layer, reducing agglomeration. Incorporating SOG and MoS leads to a 35% increase in theoretical short circuit current, enhancing wavelength absorption and overall efficiency while maintaining transparency. These results highlight the potential of SOG and MoS in scalable semi-transparent solar cell applications, paving the way for further advancements in energy generation and aesthetic architectural integration.
