2、dition, th Edition, October October 20 2020 20 EXECUTIVE SUMMARY 1 1. Executive Summary The photovoltaic (PV) industry needs to provide power generation products that can compete with both, conventional energy sources

3、and other renewable sources of energy. An international technolo-gy roadmap can help to identify trends and to define requirements for any necessary improvements. The aim of the International Technology Roadmap for Photo

4、voltaic (ITRPV) is to inform suppliers and customers about anticipated technology trends in the crystalline silicon (c-Si) based photovoltaic in-dustry and to stimulate discussion on required improvements and standards.

5、The objective of the roadmap is not to recommend detailed technical solutions for identified areas in need of improve-ment, but instead to emphasize to the PV community the need for improvement, to formulate re-quirement

6、s to meet in the future and to encourage in this way the development of comprehensive solutions. The present, eleventh edition of the ITRPV was jointly prepared by 57 leading international poly-Si producers, wafer suppli

7、ers, c-Si solar cell manufacturers, module manufacturers, PV equip-ment suppliers, and production material providers, as well as PV research institutes and consultants. The present publication covers the entire c-Si PV v

8、alue chain from crystallization, wafering, cell manu-facturing to module manufacturing, and PV systems. Significant parameters set out in earlier editions are reviewed along with several new ones, and discussions about e

9、merging trends in the PV industry are reported. The global c-Si cell and PV module production capacity at the end of 2019 is assumed to have further increased to about 200 GWp due to continued PERC capacity expansions [1

10、, 2, 3]; the market share of about 95% for the c-Si and about 5% for thin-film technologies is assumed to be unchanged [4]. The PV module market in 2019 increased by about 20% to 130 GWp. The c-Si module market shifted

11、significantly to mono-Si based products. The increased mono-Si wafer and cell capacity resulted in price reductions for mono-Si and a significant price decline for multi crystalline-Si (mc-Si) based prod-ucts. The weight

12、ed average price of c-Si modules stayed quite stable. A consequent implementation of PERC and other improvements like half-cell interconnect but also the use of larger wafers resulted in higher average module powers. The

13、 PV manufacturers installed new PERC cell and module production capacities, capable for new cell formats and upgraded existing production lines to increase cell efficiencies and to enable the use of slightly larger cell

14、formats. The price experience curve continued with its historic learning with a further increase to 23.5%. The PV industry can keep this learning rate up over the next years by continuing the linking of cost reduction me

15、asures with the implementation of cell perfections, with improved wafer material, improved cell front and rear sides, refined layouts, introduction of bifacial cell concepts, and improved module tech-nologies. The introd

16、uction of larger cell formats will contribute to reduce PV system costs. Improve-ments in all fields will result in module area efficiency increase: today’s main stream p-type mono-Si based modules reach efficiencies of

17、about 20% that will increase to 22.5% within the next 10 years, mc-Si based technologies are expected to improve from today 18.5% to above 20% until 2024. The n-type based module efficiencies will lead the market for hig

18、hest power modules from today’s 20.5% up to 23% within the next 10 years. Heterojunction (HJT) based products will reach module efficien-cies close to 24% until 2030. The combination of reduced manufacturing costs and in

19、creased cell and module performance will support the reduction of PV system costs and thus ensure the long-term competitiveness of PV power generation. All aspects are again discussed in this revision of the ITRPV. VDMA

20、continues the Roadmap activity, and updated information will be published annually to ensure comprehensive communication between manufacturers and suppliers throughout the value chain. More information is available at it
