The 7th edition of the International Technology Roadmap for Photovoltaic (ITRPV) – current trends and future challenges in c-Si PV

The photovoltaic (PV) industry has to provide power generation products that are competitive to conventional and other renewable sources of energy. The sales price of PV modules has been experiencing a continuous learning since 60 years. End of 2015 the prices reached an acceptable level of about 0.6$/Wp at a cumulative PV module shipment of 234GWp. But production capacity grows above market demand. So we experience today new round of oversupply and falling prices – below 0.4 $ /Wp currently.

Identifying technological trends and defining requirements for necessary improvements is mandatory in order to be successful in this dynamic and competitive environment.

The ITRPV identifies c-Si PV key process and product parameters and discusses trends and challenges being essential for a continuation of the PV price learning curve.

The presentation discusses important findings of the ITRPV’s 7th edition. Some technical trends for the improvement of cell and module efficiency will be discussed regarding future cost reduction potentials. LCOE (Levelised Cost Of Electricity) consideration emphasizes the long-term competitiveness of PV based power generation.

A discussion of possible growth scenarios will analyze the current situation of the PV industry in comparison to historic industrial developments and a biological process.



Dr Markus Fischer is Vice President R&D Processes at Hanwha Q Cells GmbH.  He has been a co-chairman of the International Technology Roadmap for Photovoltaic (ITRPV) since 2010. Dr. Fischer has more than 20 years of experience in the semiconductor and crystalline Silicon PV industry. He joined Q Cells in 2007 after working in different engineering and management positions with Siemens, Infineon, Philips, and NXP. As Vice president R&D Processes he is responsible for the development of process technology and production equipment of current and future c-Si solar cell concepts.

Dr Fischer studied solid state physics at the Dresden University of Technology and received his Ph.D. in Electrical Engineering in 1997 from the University of Stuttgart.
