  Abstract Carbon-based perovskite solar cells (PSCs) have exhibited unprecedented progress in the past decades, however, the deficit of open-circuit voltage and non-radiative recombination losses are the dominating limiting factors in scaling up the devices in view of commercialization. The researchers and scientists recognize the dominating factors and propose different themes to overcome the limiting factors. Among the different solutions, interfacial engineering of PSCs between the interfaces of transporting layer (electron or hole) and perovskite influences the reduction of non-radiative recombination losses with improvement in device efficiency. In this work, one-dimensional (1D) graphitic carbon nitride (g-C3N4) is synthesized through simple pyrolysis using two different mediums (ethanol and ethylene glycol). 1D g-C3N4 is interfaced between electron transport layer and perovskite absorber influences effectively in fine-tuning the work function by aligning the energy level of the fabricated mixed halide PSCs. Nanoscale engineered 1D g-C3N4 interfacial layer supports boosting the power conversion efficiency of the PSCs to 5.20% and 7.14% for tube and layered tube structures at ambient conditions. Further, the interfacial layer aids in improving thermal (tube: similar to 59.80%; layered tube: similar to 74.50%) and photostability (tube: similar to 78.65%; layered tube: similar to 87.25%) characteristics of the fabricated devices for 100 h duration at ambient conditions.
