Shingling bifacial solar cells leads to higher output power densities pout of silicon-based photovoltaic modules. This paper provides a short update on the current developments at Fraunhofer ISE in Czochralski-grown silicon bifacial “p-type shingled passivated edge, emitter, and rear (pSPEER)” solar cells. In the batch presented in this work, conventionally separated pSPEER cells are fabricated. Illuminated current-voltage measurements of the most efficient pSPEER cell results in a designated front side energy conversion efficiency of f = 21.4% for an irradiance Gf = 1000 W/m2. The pSPEER cells show similar front side efficiencies independent of the pre-separation position within the 6-inch host wafer. Considering an additional rear side irradiance of Gr = 100 W/m2, the most efficient pSPEER cell attains a total designated output power density pout = 22.8 mW/cm2.
