1. Bifacial Solar Cells
Discussion Cells and Modules
Questions:
• What is better for application of bifacial cells: ηηηηRS/ηηηηFS=1 or separately optimized
sides? Which strategy to follow in R&D?
• How urgent is a new way of IV „standard“ measurement of bifacial cells?
• How would it look like in calibration lab and/or institutes/companies?• How would it look like in calibration lab and/or institutes/companies?
(steady state or flasher, contacting,…)
• How do we define efficiency of bifacial cells? Based on physics, economy,
performance? (aperture area, masking, albedo, photon flux (per area!),…)
• How to implement different installation scenarios in IV measurement?
• How to calculate Wp price (or cost) of bifacial solar cells?
