How can I explain to my 10 year old daughter what solar cells are?
You should expain it to your daughter in a simpler way instead of the complicated scientic way.
Solar cell are the materials that can transform the sun energy into electricity.
Solar cells are the cell that can collect the solar energy from nature.
I had the same question from my son when he was 11 years old. All I did was I took him to the National Electricity museum, and it explains everything about solar cells.
According to Wikipedia: A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.
