Laser-doped selective emitter (LDSE) technology, invented and patented by the University of New South Wales (UNSW), is presently generating considerable interest in the photovoltaics industry due to its low cost, high efficiency, and suitability for mass production. The excellent results achieved to date – as high as 19.7% on small area laboratory test devices [1], and 19.0% on industrial large-area 156mm wafers [2] – are attracting a similarly impressive array of commercial partners. Nearly 10 companies are at various stages of implementation of LDSE technology variants into production and pilot production. This paper takes a closer look at the potential for mass production of LDSE-based solar cells.

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.
