Solar power has great potential, but in 2008 supplied less than 0.02% of the world's total energy supply[citation needed]. There are many competing technologies, including 14 types of photovoltaic cells,...

Read moreSolar power has great potential, but in 2008 supplied less than 0.02% of the world's total energy supply[citation needed]. There are many competing technologies, including 14 types of photovoltaic cells, such as thin film, monocrystalline silicon, polycrystalline silicon, and amorphous cells, as well as multiple types of concentrating solar power. It is too early to know which technology will become dominant.[2]
The earliest significant application of solar cells was as a back-up power source to the Vanguard I satellite in 1958, which allowed it to continue transmitting for over a year after its chemical battery was exhausted.[3] The successful operation of solar cells on this mission was duplicated in many other Soviet and American satellites, and by the late 1960s, PV had become the established source of power for them.[4] Photovoltaics went on to play an essential part in the success of early commercial satellites such as Telstar, and they remain vital to the telecommunications infrastructure today.[5]
