| Popis: | 36th European Photovoltaic Solar Energy Conference and Exhibition; 46-49 The purpose of this work is to find an accurate and high-speed method to automate module production with the tape solution. The purpose of the tape solution itself is to reduce production cost for conventional photovoltaic modules by reducing the amount of silver used in the grid on the photovoltaic cell and simplify the method of interconnection of individual PV cells. A novel method of applying bus bars and interconnecting individual cells into a module is proposed. The new method has the possibility to reduces the amount of silver by 25%. Furthermore, the interconnection of individual cells to a module is simplified, thus making the production less costly and more robust. Finally, soldering can be completed without the use of lead and at a lower temperature (150-160°C) which enables the use of cells featuring advanced temperature sensitive architecture like HJT solar cells. We have previously disclosed the results of different long-term stability tests for this tape interconnection method but this time we will present the work of automate the tape application and stringing method with the tape method. Challenges like speed and accuracy will be tested during the spring of 2019 and the result will be presented in this work. We will also present the test results of solar modules produced with the proposed automation method. |
