Publication year 2021 Abstract In order to further reduce the LCOE of PV, the conversion efficiency must increase beyond the practical limit of silicon technology (26% ). It is believed that tandem module technology, combining bottom c-Si cells with low-cost thin-film top cells, can overcome the silicon limit. Recently, bifacial glass/glass modules are gaining market share because of the increased module power output of 15-20% from the rear illumination. In this concept, the glass-glass configuration gains one the assurance of long-term reliability in exchange for the added weight of the module. Therefore, the minimum efficiency target of tandem modules should consider the energy yield of bifacial c-Si modules as ‘competition’ and therefore aim for power output densities >30 mW/cm2. Additionally, tandem modules should demonstrate same reliability, bankability and competitive cost compared to commercial PV modules. 4T bifacial tandem modules combine the best of two worlds: tandem for best spectrum utilization, and bifaciality for highest module power.
