. . .  detailed simulations Preliminary results seem to indicate the following trends: • At component level, it is possible to achieve thermal efficiencies which are substantially higher than the electrical efficiencies. • At building level, it is, for many building types and climatic conditions, not evident to make good use of the thermal energy. More details can be found in paper [4]. 3.4 Collaboration with industry In order to obtain at the end of the project deliverables, which are of direct use for . . .
. . .  warming-up of the PV elements. This increase in temperature leads to a reduction of the electrical efficiency of the PV elements. An attractive concept is to use the heating-up of the elements for other purposes; this has resulted in so-called hybrid PV components: building elements in which the integration of PV elements not only serves for electricity production. A scheme of the basic principle in a possible application is given in fig. 1: air is heated up in the cavity behind the PV elements, allowing . . .

The development of a standard procedure for the performance evaluation of hybrid PV components is organised through 4 Task Area’s and several subtasks: − Task 1 : Development of global scheme for overall performance evaluation of hybrid PV components, in close collaboration with industry − Task 2 : Further refinement of electrical performance evaluation procedures of hybrid PV components − Task 3 : Development of standardised test procedures for . . .
