Wind and solar energy in urban street-level environments are promising power sources for distributed IoT devices, but each suffers from intermittency and temporal limitations. This study proposes a hybrid power generation system combining an electret-based windmill and a dye-sensitized solar cell, and evaluates its complementary power generation characteristics under real-world conditions. In a building-shaded environment (90 lx, 0.8 m/s), the stable output of the dye-sensitized solar cell suppressed energy storage losses, resulting in a 1.7-fold increase in average output power. These results demonstrate improved stability of the hybrid system as a self-sustained energy source for urban IoT applications.
