Improvements in solar power are being developed all around the world, with scientist and researchers continuously attempting to apply electrochemistry and other sciences to solar cells in order to improve efficiency. Recently, the National Renewable Energy Laboratory (NREL) has reported one of the highest photovoltaic cell efficiencies achieved across all types of solar cells.
Researchers at the NREL have demonstrated a 45.7 percent conversion efficiency for a four-junction solar cell at 234 suns concentration.
