Hybrid energy-harvesting systems that combine perovskite solar cells (PSCs) with drop-driven triboelectric nanogenerators (D-TENGs) offer a compelling solution for continuous power generation under diverse weather conditions. Yet, the inherent vulnerability of halide perovskites to moisture and environmental stressors remains a critical barrier to their widespread deployment. To overcome this bottleneck, we introduce plasma-deposited fluorinated polymers (CFx) films as multifunctional encapsulation layers that simultaneously provide water resistance, triboelectric functionality, and optical transparency (>90 %). Plasma deposition enables conformal, room temperature, and solvent-free coating of complex surfaces, ensuring uniform protection without compromising photovoltaic performance. After encapsulation of PSCs with CFx films, power conversion efficiency remained virtually unchanged, and champion cells preserved a PCE of 17.9 %. More importantly, the devices exhibited high environmental stability, retaining over 50 % of their initial PCE for 10 days under high humidity and temperature. Furthermore, CFx layers enabled Spiro-OMeTAD compatibility with commercial UV-curable resins, leading to a thin-film hybrid PSC/D-TENG device capable of simultaneous solar and rain energy harvesting. This device maintained 80 % of its initial performance after 300 h of continuous illumination under humid conditions and demonstrated stability under continuous dripping and illumination for more than 5 h. We demonstrated that optimizing the chemical composition of CFx layers significantly enhances their triboelectric performance. In standalone operation, the optimized CFx-based D-TENG, enriched with 36.4 % of (CF2 + CF3) functional species, delivered open-circuit voltage peaks up to 110 V and a maximum power density of similar to 4 mW/cm(2) under rainwater droplets, while retaining over 85 % of its initial output after more than 17,000 droplet impacts. As a proof of concept, using the same CFx layer for both encapsulation and triboelectric functionality, the hybrid PSC/D-TENG device achieved short-circuit current densities of 11.6 mA/cm(2) under 0.5 sun illumination and peak voltages of 12 V per raindrop, enabling simultaneous solar and rain energy harvesting.
