The record-level single-junction energy yield was calculated at 717 kWh/m 2 for the world record GaAs solar cell (STC efficiency 28.8%). Energy yield is primarily determined by the amount of sunlight available, with some noticeable influence from temperature and humidity.
The radiative energy yield limit for an ideal single-junction solar cell based on 2015 global satellite data is 840 kWh/m 2. The record-level single-junction energy yield was calculated at 717 kWh/m 2 for the world record GaAs solar cell (STC efficiency 28.8%).
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.
Conferences > 2018 IEEE 7th World Conferenc... Energy yield is a key metric for photovoltaic technologies. It denotes how much energy a solar cell in an operational environment generates, and it is needed to predict return-on-investment for photovoltaic projects.
Solar cell efficiencies vary from 6% for amorphous silicon-based solar cells to 44.0% with multiple-junction production cells and 44.4% with multiple dies assembled into a hybrid package. Solar cell energy conversion efficiencies for commercially available multicrystalline Si solar cells are around 14–19%.
Accurately estimating and maximizing energy yield allows solar developers and asset owners to predict how much electricity a solar system can generate, thus shaping financial modeling and profitability analyses. Accurate yield forecasts can reduce solar financing costs by providing educated estimates around returns.
