Photovoltaics (PV) is the name of a method of converting solar energy into direct current electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon commonly studied in physics, photochemistry and electrochemistry.hotovoltaics are best known as a method for generating electric power by using solar cells to convert energy from the sun into a flow of electrons. The photovoltaic effect refers to photons of light exciting electrons into a higher state of energy, allowing them to act as charge carriers for an electric current.
The power P in watts (W) is equal to the luminous flux Ï V in lumens (lm), divided by the luminous efficacy Î· in lumens per watt (lm/W): P (W) = Ï V(lm) / Î· (lm/W). So. watts = lumens / (lumens per watt).
