  2. Solar-cell efficiency - Wikipedia

    en.wikipedia.org/wiki/Solar-cell_efficiency

    Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system , in combination with latitude and climate, determines the annual energy output of the system.

  3. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    For most crystalline silicon solar cells the change in V OC with temperature is about −0.50%/°C, though the rate for the highest-efficiency crystalline silicon cells is around −0.35%/°C. By way of comparison, the rate for amorphous silicon solar cells is −0.20 to −0.30%/°C, depending on how the cell is made.

    These effects produce an upper limit on the efficiency of silicon solar cells, currently around 20% for common modules and up to 27.1% [8] for the best laboratory cells (33.16% is the theoretical maximum efficiency for single band gap solar cells, [9] see Shockley–Queisser limit.).

    en.wikipedia.org/wiki/Shockley–Queisser_limit

    That is, of all the power contained in sunlight (about 1000 W/m 2) falling on an ideal solar cell, only 33.7% of that could ever be turned into electricity (337 W/m 2). The most popular solar cell material, silicon, has a less favorable band gap of 1.1 eV, resulting in a maximum efficiency of about 32%.

    en.wikipedia.org/wiki/Photovoltaics

    Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system , in combination with latitude and climate, determines the annual energy output of the system.

  7. Thermodynamic efficiency limit - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_efficiency_limit

    This efficiency limit of about 34% can be exceeded by multijunction solar cells. Excitonic solar cells generates free charge by bound and intermediate exciton states unlike inorganic and crystalline solar cells. The efficiency of the excitonic solar cells and inorganic solar cells (with less exciton-binding energy) [6] cannot go beyond 31% as ...
