  2. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    The theoretical studies are of practical use because they predict the fundamental limits of a solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency. Band diagram of a solar cell, corresponding to very low current (horizontal Fermi level), very low voltage (metal valence bands at same height), and ...

    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 ...

    The most common device structure for CIGS solar cells is shown in the diagram (see Figure 1: Structure of a CIGS device).Soda-lime glass of about of 1–3 millimetres thickness is commonly used as a substrate, because the glass sheets contains sodium, which has been shown to yield a substantial open-circuit voltage increase, [15] notably through surface and grain boundary defects passivation. [16]

  7. Crystalline silicon - Wikipedia

    en.wikipedia.org/wiki/Crystalline_silicon

    First generation solar cells are made of crystalline silicon, also called, conventional, traditional, wafer-based solar cells and include monocrystalline (mono-Si) and polycrystalline (multi-Si) semiconducting materials. Second generation solar cells or panels are based on thin-film technology and are of commercially significant importance.

  8. 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.

  9. Organic solar cell - Wikipedia

    en.wikipedia.org/wiki/Organic_solar_cell

    Fig. 3: Examples of organic photovoltaic materials. A photovoltaic cell is a specialized semiconductor diode that converts light into direct current (DC) electricity. . Depending on the band gap of the light-absorbing material, photovoltaic cells can also convert low-energy, infrared (IR) or high-energy, ultraviolet (UV) photons into DC ele
