  2. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    The effect of reverse saturation current on the I-V curve of a crystalline silicon solar cell are shown in the figure to the right. Physically, reverse saturation current is a measure of the "leakage" of carriers across the p–n junction in reverse bias.

  3. Two-photon photovoltaic effect - Wikipedia

    en.wikipedia.org/wiki/Two-photon_photovoltaic_effect

    A solar cell can be designed to include a region of a quantum dot structure that induces the desired confined state. In 2001, Martí et al. proposed a feasible method to meet the condition of a half-filled band. [7] There is still active research on which materials demonstrate such desired characteristics as well as the synthesis of such materials.

  4. Shockley diode equation - Wikipedia

    en.wikipedia.org/wiki/Shockley_diode_equation

    Shockley derives an equation for the voltage across a p-n junction in a long article published in 1949. [2] Later he gives a corresponding equation for current as a function of voltage under additional assumptions, which is the equation we call the Shockley ideal diode equation. [3]

  5. Saturation current - Wikipedia

    en.wikipedia.org/wiki/Saturation_current

    The saturation current (or scale current), more accurately the reverse saturation current, is the part of the reverse current in a semiconductor diode caused by diffusion of minority carriers from the neutral regions to the depletion region. This current is almost independent of the reverse voltage.

  6. Photovoltaic effect - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_effect

    The first demonstration of the photovoltaic effect, by Edmond Becquerel in 1839, used an electrochemical cell. He explained his discovery in Comptes rendus de l'Académie des sciences, "the production of an electric current when two plates of platinum or gold immersed in an acid, neutral, or alkaline solution are exposed in an uneven way to solar radiation."

  7. Heterojunction solar cell - Wikipedia

    en.wikipedia.org/wiki/Heterojunction_solar_cell

    Fill factor refers to how well the solar cell performs at its maximum power point compared to open- or short-circuit conditions. Fill factor in high-efficiency solar cells is affected by several key factors: series resistance; bulk carrier lifetimes; the saturation current density; wafer resistivity and wafer thickness.

  8. Photodiode - Wikipedia

    en.wikipedia.org/wiki/Photodiode

    This mode exploits the photovoltaic effect, which is the basis for solar cells – a traditional solar cell is just a large area photodiode. For optimum power output, the photovoltaic cell will be operated at a voltage that causes only a small forward current compared to the photocurrent. [3]

  9. Photocurrent - Wikipedia

    en.wikipedia.org/wiki/Photocurrent

    Photocurrent is the electric current through a photosensitive device, such as a photodiode, as the result of exposure to radiant power.The photocurrent may occur as a result of the photoelectric, photoemissive, or photovoltaic effect.
