Devices included in this chart of the current state of the art have efficiencies that are confirmed by independent, recognized test labs—e., NLR, AIST, JRC-ESTI, and Fraunhofer-ISE—and are reported on a standardized basis. . The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. Guidelines for inclusion reviewed. A distinction is multiple openings are not eligible). Learn how NLR can help your team with certified efficiency measurements. Higher efficiency means more power from less space, lower installation costs, and better long-term returns.
