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.
Last November, researchers in China broke the efficiency record for solar panel electricity generation using a silicon-perovskite tandem solar cell, reaching 33.9 per cent efficiency under lab ...

13 July – Researchers report the development of semitransparent solar cells that are as large as windows, [24] after team members achieved record efficiency with high transparency in 2020. [25] [26] On 4 July, researchers report the fabrication of solar cells with a record average visible transparency of 79%, being nearly invisible. [27] [28]
A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light.
This means that most solar cell manufacturers are currently equipped to produce this type of solar cells. Consequently, a large body of research is being done all over the world to manufacture silicon wafer-based solar cells at lower cost and to increase the conversion efficiencies without an exorbitant increase in production cost.
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 ...
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]
