how do solar pannels turn the suns rays into power?

Photovoltaics, or PV for short, is a solar power technology that uses solar cells or sola photovoltaic arrays to convert light from the sun into electricity. Photovoltaics is also the field of study relating to this technology and there are many research institutes devoted to work on photovoltaics.The manufacture of photovoltaic cells has expanded dramatically in recent years.Total nominal 'peak power' of installed solar PV arrays was around 3,700 MW as of the end of 2005, a 42% annual increase,and most of this consisted of grid-connected applications.
