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.

4. Air mass (solar energy) - Wikipedia

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

   Since then, the solar industry has been using AM1.5 for all standardized testing or rating of terrestrial solar cells or modules, including those used in concentrating systems. The latest AM1.5 standards pertaining to photovoltaic applications are the ASTM G-173 [10] [11] and IEC 60904, all derived from simulations obtained with the SMARTS code.

5. Shockley–Queisser limit - Wikipedia

   en.wikipedia.org/wiki/Shockley–Queisser_limit

   The Shockley–Queisser limit, zoomed in near the region of peak efficiency. In a traditional solid-state semiconductor such as silicon, a solar cell is made from two doped crystals, one an n-type semiconductor, which has extra free electrons, and the other a p-type semiconductor, which is lacking free electrons, referred to as "holes."

6. Third-generation photovoltaic cell - Wikipedia

   Such a cell can have a maximum theoretical power conversion efficiency of 33.7% – the solar power below red (in the infrared) is lost, and the extra energy of the higher colors is also lost. For a two layer cell, one layer should be tuned to 1.64 eV and the other at 0.94 eV, with a theoretical performance of 44%.

7. Thermodynamic efficiency limit - Wikipedia

   en.wikipedia.org/wiki/Thermodynamic_efficiency_limit

   Solar cells with multiple band gap absorber materials improve efficiency by dividing the solar spectrum into smaller bins where the thermodynamic efficiency limit is higher for each bin. [2] The thermodynamic limits of such cells (also called multi-junction cells, or tandem cells) can be analyzed using and online simulator in nanoHUB.

8. Allen Barnett - Wikipedia

   en.wikipedia.org/wiki/Allen_Barnett

   He was a co-inventor of a 38.5 percent efficient solar cell module built on advancements achieved on the previous DARPA VHESC project ($53 million). [11] This was cited in the March 2010 issue of Progress in Photovoltaics, Solar Cell Efficiency Tables (version 35) as “probably the highest efficiency yet measured for the experimental ...

9. Solar cell - Wikipedia

   en.wikipedia.org/wiki/Solar_cell

   For the past years, researchers have been trying to reduce the price of solar cells while maximizing efficiency. Thin-film solar cell is a cost-effective second generation solar cell with much reduced thickness at the expense of light absorption efficiency. Efforts to maximize light absorption efficiency with reduced thickness have been made.
