Active Solder Joining Electrical Buss on Photovoltaic Cells

Active solders formulations activated with Ti, Ce, Mg and Ga have been developed for optimum joining to silicon and SiO2. These solders are finding application in the attachment of copper and/or aluminum buss strips to the back planes of photovoltaic cells to direct the current from the cells and create a solar panel.

Fabrication of Solar Cell

To form the solar module, which essentially contains many solar cells, one or multiple metallic strips called busbars are connected to the surface of the solar cell. The busbars collect the entire flow of electrons or electrical current from the n-type metallic layer and deliver it to the next solar cell until it passes through the electric load. The size and number of the

How solar simulator affect the size of photovoltaic welding strip?

According to IEC61215 standard, the light emitted by solar simulator is vertically incident on the surface of photovoltaic welding strip through glass and EVA. The change of surface structure of photovoltaic welding strip will change the reflection path of light on the surface of photovoltaic welding strip, affecting the size of α 1 in Fig. 1.

How welding strip affect the power of photovoltaic module?

The quality of welding strip will directly affect the current collection efficiency of photovoltaic module, so it has a great impact on the power of photovoltaic module. The so-called photovoltaic welding strip is to coat binary or ternary low-melting alloy on the surface of copper strip with given specification.

How to reduce the shading area of a photovoltaic welding strip?

The shading area of the photovoltaic welding strip is reduced by reducing the width of the main grid line and the PV welding strip, and the total amount of light received by the solar cell is increased. However, the contact resistance of the whole PV assembly is too large, which increases the electrical loss of the photovoltaic module.

Does surface structure of heterogeneous welding strip affect power enhancement of photovoltaic module?

In order to study the influence of the surface structure of heterogeneous welding strip on the power enhancement of photovoltaic module, three kinds of heterogeneous welding strips are selected for theoretical simulation. Meanwhile, a conventional welding strip is selected as the comparison sample.

How does a photovoltaic module work?

In the photovoltaic module, the photovoltaic welding strip is packaged in EVA, and the reflected light from the surface of the photovoltaic welding strip passes through EVA and glass and enters the air. The transmission path of light is shown in Fig. 1.
