This work is the first corroboration of the synthesis, characterization, and advanced energy applications of the novel n-type Ga2O3–ZnO heaped nanorods (HNRs) via modified green route coupled microwave abetted synthesis. Upon nano-composite formation of this eco-friendly and sustainable material, there was a subsequent band gap tuning from 4.83 to 3.31 eV. Synthesized nanorods were characterized with the mixed monoclinic and hexagonal phase possessing average crystallite size of 52.51 nm. Ga2O3–ZnO HNRs sequined nickel foam electrode was assessed for energy generation in terms of the oxygen and hydrogen production. Green HNRs have greater propitiousness toward hydrogen generation with the lower overpotential and Tafel slope value of 127 mV and 117.9 mV dec−1. With the durability for 1500 min in electrolyte environment, the fabricated electrode excelled in reaching a charge storage capacity of 514 mAH g−1. In terms of the photoelectrical operation, Ga2O3–ZnO HNRs surpassed the pristine nanomaterials by effectively passivating the perovskite solar cells. Solar cell device comprised of the green HNRs as passivation agents achieved an efficiency of 16.19% and 1.04 V of the open circuit voltage (Voc). Synthesized nanomaterials have expressed sustainability and efficiency for advanced energy applications in a cost effective manner. Graphical abstract: [Figure not available: see fulltext.].
