This paper reports on the latest advances in passivated emitter and rear cell (PERC)-based shingled solar cell activities at Fraunhofer ISE. The approach taken is to fabricate 6" host wafers from
Czochralski-grown silicon and separate them after metallization and contact firing into bifacial p-type shingled passivated edge, emitter and rear (pSPEER) solar cells.

This paper provides a concise overview of existing c-Si-based 2-, 3- and 4-terminal tandem technologies, summarizes the current development status, and sets out the future roadmap. In addition, a discussion is included of what will be required over the coming years to bring these promising technologies to market, enabling commercial efficiencies above 30%.

Photovoltaics International Papers, Thin Film
This paper discusses, at both the cell and the module level, the balance between the advantages and drawbacks of increasing the cell bifaciality from a typical value of 90% towards 100%, or decreasing it towards that of monofacial cells (0%).

Because it leads to higher efficiencies than aluminium back-surface field (Al-BSF) cells, passivated emitter and rear cell (PERC) technology is attracting more and more attention in the industry and gaining market share. However, PERC technology brings new challenges with regard to the phenomenon of degradation: some monofacial/bifacial PERC cell modules were found to demonstrate much higher power degradation than Al-BSF cell modules after damp-heat (DH: 85°C and 85% relative humidity RH, 1000h) and potential-induced degradation (PID: 85°C and 85% RH, –1,500V, 96h) tests, which will be the focus of this paper.
