In work package 6 (coordinated by imec) reliability and economic life-span tests are performed at monitored outdoor locations as well as at laboratory scale, to evaluate the constructional elements manufactured in the work packages 3 to 5.

Based on the failure analysis in this work package the new solar cells are made in work package 3 so that the circle remains closed and restarts. Work packages 3 and 6 deal specifically with the quality of the patterns/connection methods required for the desired form freedom: through intermediate tests and analyses of these methods on smaller test samples a significant quality improvement of the demonstrators to be made during the project can be facilitated.

Objectives work package
The objectives of work package 6 are:

  • the improvement of confidence in investment (‘return on investment’) in BIPV systems through better substantiated predictions of economic life-span, and consequently improved insight into the cost-benefits balance (‘Levelised Cost Of Energy’);
  • harmonisation of economic life-span of thin film PV functionalities and other integrated functionalities of the constructional elements. In other words: will the PV element last just as long as the constructional element, or is the construction such that this has to be able to be replaced separately;
  • gain insight into failure mechanisms through combining experience from practice with accelerated economic life-span testing in the research environment, which will take place through:
    • accelerated economic life-span test for the demonstrator of an integrated non-transparent PV in a constructional element;
    • accelerated economic life-span test for the demonstrator of an integrated semi-transparent PV in a constructional element;
    • accelerated economic life-span test for the demonstrator of an integrated coloured PV in a constructional element;
  • making a contribution to the desired ‘self-improving chain for BIPV’ through learning from experience with the reliability and economic life-span of BIPV products and utilising this to create new and improved concepts.
