Comparison of Double-Side and Equivalent Single-Side Illumination Methods for Measuring the I–V Characteristics of Bifacial Photovoltaic Devices

The equivalent single-side illumination method was proposed as the possible way to measure the bifacial photovoltaic devices. To verify the equivalent single-side illumination method, we compared the current-voltage (I-V) characteristic measurement of bifacial single-cell laminates under double-side and equivalent single-side illumination conditions. The results showed that the short-circuit curre...
