The deployment of renewable energy, especially solar, is becoming ever more popular. It is estimated that with every 1% increase in PV cell efficiency, electricity costs would decrease by 7%; therefore, improving solar cell efficiency is very important for reducing the average electricity-generating cost of solar and driving it towards grid parity.

Welcome to the 38th edition of Photovoltaics International. There is every sign that 2018 is going to be a huge year for the industry as manufacturers continue investing in new tools and technologies. We will doubtless see many of the innovations whose evolution has been documented in these pages becoming increasingly mainstream. Sticking with bifacial solar, Fraunhofer ISE takes a wide-ranging look at a number of challenges surrounding the technology’s leap to widespread deployment. The Institute for Solar Energy Research Hamelin (ISFH) and Meyer Burger Technology AG present a novel bifacial module architecture. The University of New South Wales, Trina Solar and BT Imaging give a suggestion for predicting the variation in multicrystalline cell performance by measuring the bulk lifetime of ingots. We also have a look at PV recycling and lifecycle management from First Solar, PI Berlin’s assessment of PID issues in thin-film solar and TongWei presents a roadmap for PERC cells with 22% efficiency.

This paper reviews those associated fabrication technologies for the mass production of Ni/Cu-plated contacts. The technologies currently in use in the PV industry for plated contacts, as well as the developing technologies having high scaling-up potential, will be reviewed. In addition, the future requirements for plating metallization will be discussed.

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.
