Embodiment Construction

[0026] figure 1 Shown is a structural example of the temperature control device, which has the following features: a mounting area 110 for a stacked photovoltaic cell 50; a first and a second power supply interface 121, 122 for connecting the stacked photovoltaic cell 50 to An external power source (not shown) provides current to flow through the stacked photovoltaic cells 50 . In addition, the device has a temperature control unit 130 designed to allow the coolant F to flow through the installation area 110 to control the temperature of the stacked photovoltaic cells 50 in the installation area 110 .

[0027] figure 2 is a structural example of a device with other optional components. In the construction example shown, the temperature control unit 130 comprises a blower 131 and an additional heating device 132, enabling the blower 131 to induce a flow F, for example from the additional heating device 132 to the blower 131 (or vice versa). The additional heating device 132...

Abstract

A device for controlling the temperature of stacked photovoltaic cells (50) comprises: a holding region (110) for the stacked photovoltaic cells (50); a first and a second current connection (121, 122) for connecting the stacked photovoltaic cells (50) to an external current supply (300), in order to provide a current flow through the stacked photovoltaic cells (50); and a temperature control unit (130) designed to produce a coolant flow (F) though the holding region (110), such that the temperature of the stacked photovoltaic cells (50) in the holding region (110) can be controlled.

Description

technical field [0001] The invention relates to a device and a method for controlling the temperature of a stacked photovoltaic cell, in particular to a device and a method for acquiring solar cell electrical attenuation data. Background technique [0002] Injection levels in silicon solar cells can decay as cell temperature rises and charge carriers increase. This occurs, for example, under typical photovoltaic system operating conditions, when the temperature is below 80°C and the light conditions are up to sunlight. Photovoltaic cells degrade in the form of a reduction in efficiency, which often occurs at the start of operation. The decay that has occurred can be recovered within certain framework conditions through a restoration process, but this means an increase in expenditure. The effects leading to the attenuation are not yet well understood to allow appropriate countermeasures. Therefore there is a need to obtain the attenuation of photovoltaic modules, and to fo...
