The cost of PV modules manufactured and sold in 2012 is highly reliant on the materials used in the construction. A significant part of the market price is driven by the bill of materials, while other direct costs and depreciation form a small proportion of the total cost. Changes within the supply chain, and in the cost of the materials needed and used, are extremely important influences on the module cost and the end market price. In 2012 we have seen a slowdown in growth in the installation of both commercial and residential PV, despite dramatic falls in module costs. Some of the trends and effects of these changes on the materials supply chain for PV modules will be examined in this paper.

Our focus here at Photovoltaics International has always been on efficiency improvement and driving down the cost per watt of modules. In this issue we take a look at some of the market dynamics driving prices in the supply chain so that you can make better decisions to help reduce your overall cost per watt and increase your efficiency at the same time.

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.
