International Technology Roadmap for Photovoltaic (ITRPV) 2019

11th edition of the International Technology Roadmap for Photovoltaic (ITRPV) report released by the Germany-based Mechanical Engineering Industry Association (Verband Deutscher Maschinen- und Anlagenbau – VDMA) representing around 3300 German and European companies in the mechanical engineering industry. It  summarizes over 100 parameters along the c-Si PV value chain in numerous charts and discusses the results.

Fifty-seven leading international poly-Si producers, wafer suppliers, crystalline-Si (c-Si) solar cell and module manufacturers, PV equipment suppliers, and production material providers, as well as PV research institutes and consultants jointly provided the data basis for this edition.

The cumulated PV-module shipments surpassed 650 GWp in 2019 and the price experience curve with its historical learning continued at a learning rate of 23.5 percent.

According to the findings, the PV industry will keep this learning rate up over the next years by continuing the linking of cost reduction measures with the implementation of cell perfections, with enhanced and larger silicon wafers, improved cell front and rear sides, refined layouts, introduction of bifacial cell concepts, new cell and improved module technologies.

The market share of monocrystalline silicon (mono-Si) wafers in 2020 will be close to 75 percent and will continue to grow.
