Title: Solar cell
Inventor: KURABAYASHI KEN
IPC: H01L31/02
Filed: 1989-04-14
Abstract: PURPOSE:To reduce an influence to an output voltage even if part is shaded by connecting diodes in series and connecting capacitors in parallel with its connecting circuit. CONSTITUTION:When a solar light is radiated to solar cells 1, the cells 1 generate electromotive force, and electric energy is stored in capacitors 2 through diodes 3. A desired voltage corresponding to a multiple of the output voltage of one set is obtained as the voltage across the whole series connecting circuit. If partial cell 1 is shaded, the cell 1 of dark state becomes a normal diode to disturb passage of the electromotive force connected in series with other cell 1 due to predetermined resistance value of reverse characteristic, but since the capacitors 2 for storing the electromotive force are connected, the voltage between the terminals supplements the electromotive force of the cell 11 of dark state, and a load is not considerably affected.
