Introduction to Solar Cells
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].

What Affects Solar Cell Efficiency In Space vs. Earth?
In fact, it''s estimated that Earth''s atmosphere reflects or absorbs 55-60% of solar energy on its way to the surface. This is a good thing for us humans because it protects us from the sun''s harmful UV rays. "Terrestrial" solar panels, or solar panels on Earth, end up absorbing less solar energy.
