A variety of thin-film technologies are now entering a volume manufacturing phase. The benchmark has already been set by First Solar, Inc. in its conversion efficiencies, volume ramp and lowest cost-per-watt in the PV industry. Large-area thin-film deposition is a critical process step, dictating cell performance, reliability and manufacturing throughput. However, adoption of thin-film solar cells has been limited in the past by relatively complex and costly manufacturing processes.
The advent of rotating cylindrical magnetrons for sputtering is demonstrating the potential to significantly reduce thin-film manufacturing costs. In this paper we discuss the basics of the technology and the developments taking place with some of the leading suppliers of sputtering target technology for the PV industry.

The fourth edition of Photovoltaics International was published in May 2009. It features an exclusive interview with First Solar’s Bruce Sohn on manufacturing and the future. SunPower also outlines the economic benefits of LCOE drivers in Power Generation and Fraunhofer IPA gives an overview of automation in the photovoltaic industry.

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.

In this paper, an even greater reduction in wafer thickness, down to 130μm, is evaluated, and the critical steps in terms of breakage rates in cell and module production processes are reviewed. Finally, the mechanical stability and reliability of these thin HJT cells in glass–backsheet and glass–glass module types are addressed.

To embrace the terawatt-scale challenge of the PV market growth, a low-carbon and resource-efficient pathway has to be guaranteed. An approach for doing this is to enable market mechanisms that account for the greenhouse gases emissions, and their associated costs, from PV systems and components.
