  2. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current , voltage , or resistance ) vary when it is exposed to light.

  3. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    In thick solar cells there is very little electric field in the active region outside the space charge zone, so the dominant mode of charge carrier separation is diffusion. In these cells the diffusion length of minority carriers (the length that photo-generated carriers can travel before they recombine) must be large compared to the cell ...

  4. Concentrator photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Concentrator_photovoltaics

    Though the cost of multi-junction solar cells is roughly 100 times that of conventional silicon cells of the same area, the small cell area employed makes the relative costs of cells in each system comparable and the system economics favor the multi-junction cells. Multi-junction cell efficiency has now reached 44% in production cells.

  5. How Much Does It Cost To Charge an Electric Car? - AOL

    Using this math, the average car with a 360-mile range would cost about $36.38 to fill up, which is still a bit higher than the average electric vehicle charge cost. Final Take. Electric vehicles ...

  6. Solar vehicle - Wikipedia

    en.wikipedia.org/wiki/Solar_vehicle

    Most student built solar cars lack the safety and convenience features of conventional vehicles and are thus not street legal. The first solar family car, Stella, was built in 2013 by students in the Netherlands. [2] This vehicle is capable of 890 km (550 mi) on one charge during sunlight. It weighs 390 kg (850 lb) and has a 1.5 kWh solar array.

  7. Photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Photovoltaics

    Solar panels are usually guaranteed for 25 years (but inverters tend to fail sooner), [160] [161] with little maintenance or intervention after their initial set-up, so after the initial capital cost of building any solar power plant, operating costs are extremely low compared to existing power technologies.

  8. Charge carrier density - Wikipedia

    en.wikipedia.org/wiki/Charge_carrier_density

    Charge carrier density, also known as carrier concentration, denotes the number of charge carriers per volume. In SI units, it is measured in m −3. As with any density, in principle it can depend on position. However, usually carrier concentration is given as a single number, and represents the average carrier density over the whole material.

  9. Solar bus - Wikipedia

    en.wikipedia.org/wiki/Solar_bus

    A solar bus or solar-charged bus is a bus that is powered exclusively or mainly by solar energy. Solar-powered bus service is referred to as a solar bus service. The use of the term "solar bus" normally implies that solar energy is used not only for powering electric equipment on the bus, but also for the propulsion of the vehicle.
