Flux should be added. Then the chip placed carefully into position. Note getting solder contact over just half the thermal pad is usually considered adequate. Hot air is applied (again 240C) at the same time as turning up the soldering iron under the board. Keep an eye on the solder on the pads and aim to get all melted at the same time.
A solar cell is the fundamental element of a solar panel, a device that converts sunlight into electricity.

A 60-cell photovoltaic (PV) module was analyzed by optimizing the interconnection parameters of the solar cells to enhance the efficiency and increase the power of the PV module setup.
Using solder and a soldering iron, you''ll then bond each piece of tabbing wire to the cells. Bond two tabbing wires onto the back of each cell, along the same path where the front of the cell''s contact pads run. Half of the wire''s length should extend beyond the cell to reach the front of the next cell. Step 2: Solar Cell Connection

Additionally, each cell is not connected for the ribbon soldering process, and thus it eliminates damage to the solar cell and reduces electrical loss resulting from the resistance of the ribbon [20], [21]. Furthermore, there is no space between the cells, and thus it is possible to fabricate a module with high density such that a module ...
You can solder the strip directly to the solar cell with flux or, pre-solder or "tin" each strip and then solder it to the solar cell. The goal is to get a solid solder connection to the solar cell or it will not transfer current.
