Abstract
In order to generate sufficient electricity in a small light converging solar module, a power generation solar cell is provided with four movement solar cells, situated around it. Below the respective movement solar cells, electromagnets are situated, connected to corresponding movement solar cells. The power generation solar cell, the movement solar cells, and the electromagnets are all mounted on a cell holder, around which a permanent magnet in the form of a ring is provided. When a converged spot moves its position from on the power generation solar cell to a position off the power generation solar cell, and onto one of the movement solar cells, electricity is supplied to the corresponding electromagnet, thereby moving the cell holder due to attracting forces generated between the electromagnet and the permanent magnet. After the cell holder is moved to such a point where the converged spot correctly falls on the power generation solar cell, the cell holder stops its movement.
