Electrical Characteristics of Photovoltaic Cell in Solar-Powered Aircraft During Cruise

Aiming to study the electrical characteristics of photovoltaic cells during flight solar-powered unmanned aerial vehicles, this work combines a cell equivalent circuit model and thermodynamic model. The influence wing surface temperature its influencing factor-solar radiation is primary concern. A solar established explore impact irradiance on output. Atmospheric four basic parameters cell, including open-circuit voltage, short-circuit current, current at maximum power point under standard conditions are treated as input parameters. temperature, variation output studied with altitude changing from 0 35 km time 24 h in spring equinoxes. Results find that increase altitude, decreases first then increases. voltage increases, voltage-time curve varies altitudes below 25 above 30 km. peak available an between 15 20 findings can be applied energy generations flows vehicles.
