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.
2008 - New record achieved in solar cell efficiency. Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have set a world record in solar cell efficiency with a photovoltaic device that converts 40.8% of the light that hits it into electricity. However, it was only under the concentrated energy of 326 suns ...
30 May - A team at Fraunhofer ISE led by Frank Dimroth developed a 4-junction solar cell with an efficiency of 47.6% - a new world record for solar energy conversion. [ 23 ] [ importance? 13 July – Researchers report the development of semitransparent solar cells that are as large as windows, [ 24 ] after team members achieved record ...
CIS and CGS solar cells offer total area efficiencies of 15.0% and 9.5%, [33] respectively. In 2015, the gap with the other thin film technologies has been closed, with record cell efficiencies in laboratories of 21.5% for CdTe (FirstSolar) and 21.7% for CIGS (ZSW). (See also NREL best research cell efficiency chart. [34])
The only national laboratory solely dedicated to energy efficiency and renewable energy, NREL helps its industry partners create innovative components, fuels, infrastructure, and integrated systems for battery electric, fuel cell, and other alternative fuel on-road, off-road, and non-road vehicles, including emerging technologies for aviation ...
The shaded area under the red line represents the maximum work done by ideal infinite multi-junction solar cells. Hence, the limiting efficiency of ideal infinite multi-junction solar cells is evaluated to be 68.8% by comparing the shaded area defined by the red line with the total photon-flux area determined by the black line.
Solar cell efficiencies. In August 2014 First Solar announced a device with 21.1% conversion efficiency. [42] In February 2016, First Solar announced that they had reached a record 22.1% conversion efficiency in their CdTe cells. In 2014, the record module efficiency was also raised by First Solar from 16.1% up to 17.0%. [43]
