How can we use the sun's heat to convert it into electricity or other energy in hot weather?

Vigorously develop the solar energy industry.

I saw an experiment in which different metal wires, such as copper wire and iron wire, are wound together into several strands. Connect the copper wire to one pole and the iron wire to the other pole, then place them next to the stove and use an ammeter to check if there is power! Perhaps there will be very efficient ways to use solar energy in the future, such as "a kind of high-efficiency thermal generator."
