    NASA used solar cells on its spacecraft from the beginning, their second successful satellite Vanguard 1 (1958) featured the first solar cells in space. Solar cells were first used in a prominent application when they were proposed and flown on the Vanguard satellite in 1958, as an alternative power source to the primary battery power source ...

    Dye-sensitized solar cell – DSC or DYSC) is a low-cost solar cell belonging to the group of thin film solar cells. Effect of sun angle on climate – as the angle at which sunlight strikes the Earth varies by location, time of day, and season due to the Earth's orbit around the Sun and the Earth's rotation around its tilted axis.

    The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...

  9. Solar-cell efficiency - Wikipedia

    en.wikipedia.org/wiki/Solar-cell_efficiency

    Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system , in combination with latitude and climate, determines the annual energy output of the system.
