As of 2024, the world record for solar cell efficiency is 47. 6%, set in May 2022 by Fraunhofer ISE, with a III-V four-junction concentrating photovoltaic (CPV) cell. 1%, set in 2019 by multi-junction concentrator solar cells developed. . Balance-of-system efficiency; typically, 80% to 90%, but stipulated based on published inverter efficiency and other system details such as wiring losses. Energy Ratio, total measured production divided by total model production, thus considering the effects of both Availability and Performance. . 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. Solar panel type is one of the biggest factors affecting efficiency.
