“…PERC solar cells originated in 1983 but were first reported in 1989 with an efficiency of 22.8% . The conventional Si PERC cells contain a thick p-type Si bulk as the absorber in the middle along with a certain design structure for the front side and back side, as shown in Figure a . As the key material for photoelectric conversion in PERC cells, p-type Si is textured on the front side by a suitable etchant (i.e., KOH or NaOH) and polished on the rear side, aiming to enhance the photon transmission into Si bulk and increase the photon path length …”

Perovskite/silicon tandem solar cells have been intensively studied in recent years, and their efficiencies have rapidly increased owing to the numerous efforts in this field. A question about which type of silicon solar cell is the most suitable subcell in tandem devices emerges. Herein, three attractive silicon solar cells are summarized, including passivated-emitter rear-cell (PERC), tunnel oxide passivated contact (TOPCon), and heterojunction (HJT) cells. Their structures and features are elucidated for a clear understanding of the mechanism and potential of optimum performance. Moreover, the characteristics and performance of perovskite/silicon tandem cells with PERC, TOPCon, and HJT subcells are contrasted and discussed. The significant contribution of the passivation layer and structure design on both sides to photovoltaic properties of tandem devices is emphasized. Especially, the recombination layer between two subcells is analyzed in depth in terms of material chemistry, light absorption, and charge transport with a review on preparing the optimized structure.

“…In particular, PERC solar cell architecture introduces the passivation of the n-doped layer, known as emitter. [33] With PERC architecture, a significant improvement in terms of efficiency has been achieved in crystalline silicon solar cells. Although more process steps are necessary to fabricate the PERC cells compared to Al-BSF, the increase in performances allows a significant lowering of costs/Watt.…”

Solar cells cost per Watt has decreased so quickly in the last years that photovoltaic (PV) module manufacturing costs cover only a small fraction of the total costs of a PV plant. Essentially, the installation and operation costs as well as the costs for the management of starting materials are the main factors today the most important levers for total costs decrease. PV technology has advanced towards both efficiency and average energy generation increasing by light capture optimization and losses minimization. This work analyses the state-of-the-art of PV technology for terrestrial application and discusses the perspectives for future development, which aims at overwhelming limitation posed by material properties. Higher focus is given to the most promising current technology such as silicon heterojunction solar cells and on future developments based on tandem cell approaches.
