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.
In 2022, researchers at Fraunhofer Institute for Solar Energy Systems ISE in Freiburg, Germany, demonstrated a four-junction concentrator solar cell with an efficiency of 47.6% under 665-fold sunlight concentration. [31] [32] The theoretical limiting efficiency under concentration approaches 65% for 5 junctions, which is a likely practical ...
SHJ has the highest efficiency amongst crystalline silicon solar cells in both laboratory (world record efficiency) [2] [27] [29] and commercial production (average efficiency). In 2023, the average efficiency for commercial SHJ cells was 25.0%, compared with 24.9% for n -type TOPCon and 23.3% for p -type PERC. [ 34 ]

Indiana scored 15.88 out of a total 100 points in the study that used electricity costs, installation costs, potential solar energy, existing solar capacity and solar polices to grade each state.
In 2013, First Solar acquired GE's thin film solar panel technology in exchange for a 1.8% stake in the company. [38] Today, First Solar manufactures over 3 gigawatts with an average module efficiency of 16.4% in 2016. [39]
