Development of a Solar Power System for Stratospheric Balloon
Recent advancement in photovoltaic have sparked the integration of solar cells into the development of stratospheric balloon. Contrary to solar cells on Earth, solar cells on stratospheric balloon operate at low temperatures (-60°C to 0°C). This project aims to investigate the performance of solar c...
