U.C. Boehnke, Leipzig, 2020

The new Technology Readiness Questionnaire is online. Please send your input to by August 27th, 2021.

The International Technology Roadmap for Photovoltaic (ITRPV) is a successful and internationally appreciated roadmap for the solar industry to which international cell and module producers, leading research institutes, mechanical and plant engineers and material manufacturers contribute. The 12th Edition was published in April 2021. During summer we ask for the technology readiness of selected parameters of different diagrams in the ITRPV. The international Technology Readiness Level (TRL) has 9 categories, ranging from category No. 1 for the earliest stage basic research to the category No. 9 for the final product. We combined them in 4 categories, as shown here:

With the help of these categories, parameters and technologies are estimated and assessed. The new Technology Readiness Questionnaire is now online. Interested experts are asked to complete this Questionnaire by August 27th, 2021 and send it to
