Solar cell arrays for concentrator photovoltaic modules

A method for testing the die-attach quality of a photovoltaic cell assembly, in particular, for electrical inline monitoring of a photovoltaic cell die-attach quality during the manufacturing of a concentrator photovoltaic module, comprises the steps of providing a photovoltaic cell assembly comprising at least one photovoltaic cell, in particular, a concentrator photovoltaic cell, attached to a heat sink, injecting a current into the photovoltaic cell assembly, measuring the voltage across the photovoltaic cell during the current injection, and determining the relative voltage drop over the duration of the current injection, whereby insufficiently bonded photovoltaic cell assemblies can be identified and screened.

Method for testing the die-attach of a photovoltaic cell assembly

Apparatus for the industrial production of photovoltaic concentrator modules, consisting of a module frame, a lens disc, a sensor carrier disc and an electrical line routing arrangement, comprising the following features: a) a mount for the stress-free mounting of a module frame by means of clamping elements on both longitudinal sides and stop elements on both transverse sides, wherein the setting of the clamping elements takes place by means of the displacement and rotation of a switching rod, b) a device for a punctiform application of acrylic and a linear application of silicone onto the bearing surfaces of the module frame, c) a respective device for placing the sensor carrier disc or the lens disc, wherein these discs are transported in a stress-free fashion by means of special suction apparatuses and are emplaced with a centrally starting, predetermined contact pressure, d) a device for measuring the respective disc position and for positioning a sensor carrier disc or a lens disc, e) a device for the fine adjustment of the lens disc with respect to the CPV sensors of the sensor carrier disc by means of a camera, wherein the camera is adjusted in such a way that the position of its optical axis impinges on the geometrical midpoint of a CPV sensor, f) a device for curing the silicone application between the module frame and the respective disc by means of a plurality of UV light emitters, and g) devices for transporting the workpieces to be processed.

Apparatus for the industrial production of photovoltaic concentrator modules

The invention relates to a photovoltaic concentrator module comprising at least one lens and at least one photovoltaic cell, further comprising a distance adjustment means configured to adjust the distance between the at least one lens and the at least one photovoltaic cell. Using the distance adjustment means, the cell and the lens can be kept at a desired distance, e.g., the focal distance. The distance adjustment means can be a pressure varying means. The invention further relates to a photovoltaic concentrator array comprising a plurality of photovoltaic concentrator modules and to a method for improving the energy conversion efficiency of a photovoltaic concentrator module.

Photovoltaic module with adjustable height concentrator

Apparatus for the industrial wiring and final testing of photovoltaic concentrator modules, consisting of a module frame, a lens disc, a sensor carrier disc and an electrical line routing arrangement, comprising the following features: a) a laser contact-making device for the contactless connection of connecting lines between the individual sensors and of connecting elements and of collective contact plates, wherein the line routing arrangement on the sensor carrier disc as basic structure has, in each case, five CPV sensors connected in parallel, and these parallel circuits are connected in series, b) a device for testing electrical properties, wherein a specific voltage is applied to CPV sensors themselves, and the light emitted by them via the lenses is detected and assessed, c) a device for testing tightness of finished concentrator modules, wherein compressed air is applied to the modules in the interior and the emission of compressed air is checked.
