Explain the working principle of thin-film solar panels.

• Thin-film solar panels operate by absorbing heat from the sun and converting it into electricity.

• Thin-film solar panels work by using mirrors to reflect sunlight onto the panels.

• Semiconductor materials are used to convert sunlight into electricity.

• Thin-film solar panels generate electricity by using water as a conductor.
