From sunlight to electricity - Curious

Aug 17, 2015· Photovoltaic solar panels absorb this energy from the Sun and convert it into electricity. A solar cell is made from two layers of silicon—one ‘doped’ with a tiny amount of added phosphorus (n-type: ‘n’ for negative), the other with a tiny amount of boron (p-type: ‘p’ for positive) The doping ingredients create extra electrons in the n-type layer and ‘holes’ (missing electrons) in the p-type layer.

How Solar Produces Power | SunPower Solar Blog

Jan 09, 2020· Confusion over the impact of heat and light in solar power starts with the fact that there are different types of solar power. One type of power, called solar thermal, does use the sun's light to generate heat which can be used for things like generating steam. The other type of solar power is generated by photovoltaic (PV) solar panels, which use light to generate electricity directly.
