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. Shockley–Queisser limit - Wikipedia

   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%.

Site detail view (in this case for the location Bhadla, Rajasthan, India) summarises the data important for preliminary site assessment of a photovoltaic power plant Global map of Photovoltaic Power Potential downloadable via the Global Solar Atlas (GSA 2.2) Download section feature with more than a ...

5. 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 ...

6. Theory of solar cells - Wikipedia

   en.wikipedia.org/wiki/Theory_of_solar_cells

   However, the solar frequency spectrum approximates a black body spectrum at about 5,800 K, [1] and as such, much of the solar radiation reaching the Earth is composed of photons with energies greater than the band gap of silicon (1.12eV), which is near to the ideal value for a terrestrial solar cell (1.4eV). These higher energy photons will be ...

7. Air mass (solar energy) - Wikipedia

   en.wikipedia.org/wiki/Air_mass_(solar_energy)

   This apparently counter-intuitive result arises simply because silicon cells can't make much use of the high energy radiation which the atmosphere filters out. As illustrated below, even though the efficiency is lower at AM0 the total output power (P out) for a typical solar cell is still highest at AM0. Conversely, the shape of the spectrum ...
