摘要

Accurate, fast and reliable measurement of the spectral responsivity of a solar cell is an important step in evaluating the electrical performance of competing photovoltaic (PV) technologies and products. A few research groups, including one at that National Institute of Standards and Technology (NIST), have investigated ways to measure the spectral responsivity, and hence the external quantum efficiency, of solar cells using measurement techniques that employ light emitting diodes (LEDs).
