A solar cell can produce up to 2 W of energy. When load current is zero, its voltage becomes maximum and is known as open-circuit voltage V oc.When load current increases, short circuit current I sc is reached, and voltage becomes zero. Power from a solar cell shows a bell-type behavior between these two extremes of zero power.
The U.S. Department of Energy Solar Energy Technologies Office (SETO) supports PV research and development projects that drive down the costs of solar-generated electricity by improving efficiency and reliability.

William Schockley and Hans Queisser in 1961 calculated for a single pn junction solar cell the maximum theoretical efficiency, known as the detailed balance limit or Schockley-Queisser, limit by examining the amount of electrical energy extracted per incident photon which indicated maximum solar conversion efficiency of about 33.7% for bandgap ...
There are two main types of solar energy technology: photovoltaics (PV) and solar thermal. Solar PV is the rooftop solar you see on homes and businesses - it produces electricity from solar energy ...
Spectra are commonly plotted also as a function of the (vacuum) wavelength (lambda ) of light instead of as a function of energy. Such a plot of (dj_{mathrm {E}}/dlambda ) of the solar spectrum as a function of the wavelength (lambda = {c}/{nu } ) with the vacuum velocity of light (c) is shown in Fig. 2.2.Although the spectra in both figures are the same, the …

The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. Improving this conversion efficiency is a key goal of research and helps make PV technologies cost-competitive with conventional sources of energy.
