Solar Cells with High Efficiency
高效太阳能电池

A method and an apparatus for improving solar light absorption and energy storage of solar cells are designed. The V-A characteristics of a solar cell and the charging and discharging characteristics of a Farah capacitor are presented. The apparatus uses a concave mirror to achieve the absorption of solar light on both sides of a solar cell and uses a Farah capacitor to store the solar energy. Compared with the traditional apparatus using single-side solar cells and storage battery, this apparatus has the advantages of high absorption effciency, fast charging and large discharging current. It can be widely used in street and corridor lighting and other related fields.
