Why is e = hv important in pv cell considerations?

E=hv is an equation important when dealing with light. E refers to the energy of a photon; h is Planck's constant and v is the wavelength. According to this equation, light particles called photons travels in packets of energy. This is important in pv cells because this is the technology used to harness solar energy which is converted to electricity. The amount of energy should be estimated to know the appropriate material of construction of the pv cell to achieve optimum conditions. In this way, the pv cell could maximize the sun's energy.

This skydiver is using a wingsuit to soar through the air. ... Resembling something between a flying squirrel and a snow angel, the wingsuit allows skydivers and BASE jumpers to leap out into the void, spread their arms and soar through the air. In a sense, wingsuit flying is a cross between skydiving and hang gliding.
