  3. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    By the 1960s, solar cells were (and still are) the main power source for most Earth orbiting satellites and a number of probes into the solar system, since they offered the best power-to-weight ratio. However, this success was possible because in the space application, power system costs could be high, because space users had few other power ...

  4. Solar energy conversion - Wikipedia

    en.wikipedia.org/wiki/Solar_energy_conversion

    By the 1960s solar power was the standard for powering space-bound satellites. In the early 1970s, solar cell technology became cheaper and more available ($20/watt). Between 1970 and 1990, solar power became more commercially operated. Railroad crossings, oil rigs, space stations, microwave towers, aircraft, etc.

    Hoffman KP706 Trans Solar Radio (1959), running on batteries or with a Hoffman solar cell array on the top. Hoffman made great strides in making the solar cell a practical and useful source of renewable energy. From 1957 to 1960, he improved its efficiency from 4.5 to 14 percent and lowered the production cost to make it a marketable item.

    The Sanyo HIT (Heterojunction with Intrinsic Thin layer) solar cell is composed of a mono thin crystalline silicon wafer surrounded by ultra-thin amorphous silicon layers. [27] Sanyo Energy opened its solar module assembly plants in Hungary and in Mexico in 2004, and in 2006 it produced solar modules worth $213 million. In 2007, Sanyo completed ...

  9. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
