PV manufacturing capacity expansion announcements in 2017 far exceeded the three preceding years, despite the significant slowdown in new plans in the third quarter. The year was dominated by c-Si solar cell
expansion plans and the return of CdTe and CIGS thin-film activity – the highest seen in many years. This quarterly report reviews the fourth quarter activity as well offering a full-year review and analysis of a
record year across all segments of upstream manufacturing.

Welcome to the thirty-ninth edition of Photovoltaics International. We go to press just a few days after the conclusion of our PV CellTech conference in Penang. The focus for all the PV CTOs, chief scientists, materials providers, equipment manufacturers and others gathered for the summit was how to keep pushing the industry towards a standard 20% efficiency while also expanding in scale. That expansion ought to be 100GW in three years if demand is to be met, according to one speaker. CEA-INES researchers look at the benefits of exploiting the symmetrical a-Si/c-Si/a- Si structure of silicon heterojunction cells to use ultrathin wafers. Another innovation that delivers materials savings is of course diamond wire sawing and, again, scale and efficiency are dual drivers. Here, CEA demonstrates the need for, and processes involved in, closely monitoring the cutting process to ensure wafer quality is consistent and productivity can remain at the desired level. We look at different sides of bifacial technology (pun intended) starting with JinkoSolar’s appraisal of its mono PERC bifacial cells built using standard production technology and racking up average efficiencies of 21.8%. Away from the crystalline silicon world, German research firm OPVIUS explores how a combination of printing methods could open the door to freeform PV modules, unleashing an entirely new suite of product options and applications. ECN Solar reveals the results of an industrial-scale trial process to develop an n-type bifacial IBC solar cell that is based on tube diffusion and a simultaneous single-step screen-print of contacts at both polarities. Last but not least, CSEM looks at the impact the emerging diversity in cell technology and module architecture is having on metrology.

This paper presents an analysis and the results of extensive simulations of the efficiency limits and roadmap to 25.5% of a tunnel oxide passivated contact (TOPCon) solar cell, on the basis of an efficiency level of 25.21% (designed area, identified by ISFH) achieved through three years of continuous technical optimization on a pilot line at Longi.

The development of new ways of increasing the production throughput for passivated emitter and rear cells (PERCs), as the major solar cell technology in the global market, is an area of great interest to the PV community. This paper presents approaches for significantly increasing the throughput of PERC production processes. The main focus is on the tube furnace processes for the emitter formation and oxidation, with the introduction of the High Temperature Stack Oxidation (HiTSOx) approach. Additional approaches that are currently under investigation at Fraunhofer ISE for increasing the throughput for wet-chemical, printing and laser processes will also be briefly outlined.

The holy grail of every solar cell producer is the creation of a lowcost interdigitated back-contact (IBC) solar cell with an efficiency greater than 25%, a goal that can be found in almost every roadmap presentation. In this paper it will be shown that we are not far away from achieving this target, since IBC devices, with different process complexities, are already in production at several companies.
