Hello everyone, I''m new to the DIY solar panel game. I''ve read many articles and watched a bunch of videos, so I have a kind of decent grasp on the whole process, but they didn''t answer all of my questions. I''m sure I will have more questions down the road but here is my first one: What is the best temperature for soldering the solar cells
The process of choice is welding or soldering.

Since the passivation by the amorphous silicon layers of SHJ cells cannot withstand temperatures above 250 °C [7, 8], low-temperature soldering is considered as a suitable technology. The main challenge is to overcome the known weak adhesion between metallization paste and wafer surface, observed after soldering on SHJ solar cells .
A set of the aforementioned SHJ solar cells is employed to test the wetting behavior of the metallization pastes and to investigate the mechanical adhesion after soldering (see left column (orange) of process sequence in Figure 1).
Cold solder joints occur when the temperature during the soldering process is not high enough, and they are difficult to see with the naked eye. “It turned out to be important that we had agreed in advance with the manufacturer on the criteria for replacing modules,” says CEA's Director of Technology and Quality, George Touloupas.
However, solder joints on low-temperature metallization pastes of SHJ cells are known for a weak adhesion to the cell surface. This work is dedicated to a better understanding of the interaction between solder and low-temperature metallization on SHJ solar cells.
Prior to soldering, the wettability of the screen printed and cured low temperature metallization with the liquid solder alloys is analyzed. The cells are placed on a hotplate and pre-heated to 200 - 220 °C so that the solder melts as soon as it comes in contact with the metallization.
ABSTRACT: Interconnecting silicon heterojunction (SHJ) solar cells by low-temperature ribbon soldering allows the use of standard stringing equipment and might therefore be the cheapest and most straightforward implementation in existing fabrication lines.
