Power conversion efficiency measures how effectively a solar cell converts sunlight into usable electricity. It is calculated by dividing the electrical power output by the incident solar power under standard test conditions. Improving PCE is the primary goal in photovoltaic research, as higher efficiency means fewer panels are needed to generate the same amount of power.

The lab just achieved a new record PCE of 24 percent on their perovskite tandem cells.
