Abstract

We report on measurements of large bifacial solar cells using a new LED-based measurement setup for wavelength range 290 – 1300 nm. The measurement uncertainty in visible is 1.7% (k=2). Main challenges in the measurements are the spatial uniformity and the measurement of short circuit current. These topics are discussed in detail.
