introduction
What does photovoltaic mean?Photovoltaic systems contain cells that convertsunlight into electricity. Inside each cell there arelayers of a semi-conducting material. Light falling on the cell creates an electric field across the layers, causing electricity to flow. The intensity of the light determines the amount of electrical power each cell generates.
A photovoltaic system does not need bright sunlight in order to operate. It can also generate electricity on cloudy and rainy days from reflected sunlight.

Music May Make Solar Cells More Efficient
A study at Queen Mary University of London and Imperial College London (both UK) investigated how ambient sound vibrations can enhance the performance of a printed solar cell with zinc-oxide (ZnO)why does pop and rock music boost energy generation in these d solar cells mores than classical music? "The nanorods in the cells respond most strongly to 10 kHz sounds,

Human Hair Solar Panel by Milan Karki
• 18-year old Inventor, Milan Karki, from rural Nepal, claims to have come up with a new type of solar panel that uses human hair, a design he thinks could provide the developing world with cheap, green electricity. He has built several prototypes
• His panel, which produces 18 Watts (9 volts at 2 amps)
probably the main one is that human hair does not conduct electricity but it can conduct an electric current.
