TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The cup body or mirror body and/or the absorbing means are rotatable or tiltable by an arbitrary angle. The inclination angle or orientation angle of the cup body or mirror body and/or the absorbing means is adjustable, depending on the seasonal sun position. At least one carrier is arranged to, at or below the cup body or mirror body and/or the absorbing means. The carrier comprises at least one recess, groove, hole and/or slot, by means of which at least one electrical line is guided between the absorbing means. At least one, preferably at least two-component is formed from at least two independent, mutually displaceable elements. The carrier, preferably at least one extension of the carrier is insertable in the side guide. The side guide comprises at least one adjustment- or adjusting mechanism for rotating or tilting the cup body or mirror body and/or the absorbing means comprising the carrier by an arbitrary angle. At least one cooling means, preferably a cooling body, which is associated with the absorbing means, is filled with at least one fluid. The cooling body is arranged between at least two windows or panes. The cooling body cools the absorbing means and accommodates and transports the thermal energy according to the type of thermovoltaic. At least one light source, preferably at least one light emitting diode is arranged in the side of the carrier facing away from the incident light. At least one guidable lamella element is arranged in the region of the absorbing means facing away from the side of the sun, preferably in the region behind the absorbing means. At least one side guide or side support, which is led along at least one electrical line for wiring the absorbing means is glued by means of at least an adhesive structure, at least one double-sided adhesive tape or glue. The cup body or mirror body is formed from at least one straight portion, preferably according to the type of at least one chord. The individual sections are of same or different sizes. The individual sections comprise a decreasing cross-sectional dimension with an increasing distance from the associated absorbing means. At least one unit formed from cup body or mirror body and the absorbing means is shiftable or movable, preferably collapsible and extendable. The shading or transparency of a inclined roof or flat roof is controllable by the displaceability or movability.
