Solar cell Nov 28, 2016

To convert the energy of sunlight to power devices. When the solar radiation, voltage, be current, used in satellites, spacecraft solar cells are made of semiconductors (Silicon photocell). Exposure to sunlight when the surface of the solar cell, semiconductor PN junction formed on both sides of the potential difference. Its efficiency is above 10%, typical output power was 5~10 milliwatts per square centimeter (open area).
