Solar cell system and method for controlling solar cell system

A solar cell system, comprising:

• a first solar cell including a first terminal and a second terminal;
• a second solar cell including a third terminal and a fourth terminal, the third terminal being electrically connected to the first terminal;
• a voltage converter including a fifth terminal and a sixth terminal, the fifth terminal being electrically connected to the fourth terminal, and
• an interconnect electrically connecting the sixth terminal and the second terminal,
• the voltage converter being configured to cause a second absolute value to be smaller than a first absolute value, the first absolute value being determined based on a difference between a first potential difference and a second potential difference, the first potential difference being between the first terminal and the second terminal, the second potential difference being between the first terminal and the fourth terminal, the second absolute value being determined based on a difference between the first potential difference and a third potential difference, the third potential difference being between the first terminal and the sixth terminal.
