<human>: I've been hearing a lot about a new type of solar power. What is it and how can I use it?
<bot>: Solar power is the conversion of sunlight into electricity using photovoltaic cells. Photovoltaics are made up of semiconductors that absorb photons from the sun, creating an electric current when exposed to light. This energy can then be used for various applications like lighting, communication, transportation, or even heating water.
