2. Solar panel - Wikipedia

   en.wikipedia.org/wiki/Solar_panel

   A [ 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. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.

3. Dye-sensitized solar cell - Wikipedia

   en.wikipedia.org/wiki/Dye-sensitized_solar_cell

   A selection of dye-sensitized solar cells. A dye-sensitized solar cell ( DSSC, DSC, DYSC [1] or Grätzel cell) is a low-cost solar cell belonging to the group of thin film solar cells. [2] It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system.

4. Solar-powered radio - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_radio

   The solar powered radio first came into existence in the 1950s. An experimental model, developed by General Electric, weighed just 10 ounces and was capable of working without light and recharging. It contained seven solar cells, four transistors and a small battery. [2] [3] In 1954, Western Electric began to sell commercial licenses solar ...

5. Photovoltaics - Wikipedia

   en.wikipedia.org/wiki/Photovoltaics

   Photovoltaics ( PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors . A photovoltaic system employs solar modules ...

6. Photovoltaic system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_system

   A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...

7. Solar power by country - Wikipedia

   en.wikipedia.org/wiki/Solar_power_by_country

   The worldwide growth of photovoltaics is extremely dynamic and varies strongly by country. In April 2022, the total global solar power capacity reached 1 TW. [3] In 2022, the leading country for solar power was China, with about 390 GW, [4] [5] accounting for nearly two-fifths of the total global installed solar capacity.
