Increasing the Efficiency of Solar Cells By Transfer of Solder

摘要

Embodiments relate to thickening a contact grid of a solar cell for increased efficiency. A mold containing soldering material is heated. The mold is aligned with the contact grid such that the soldering material is in physical contact with the contact grid. The mold is re-heated, transferring the solder material from the mold to the contact grid to create a thickened contact grid.

主权项

1. A solar cell, prepared by a process comprising the steps of:
for a first body comprising a first mold, the first mold comprising at least one hollowed out area containing a solder material, heating the first body such that the solder material softens and forms within the hollowed out area; aligning the first body with a second body, the second body comprising a contact grid with a first thickness in communication with a diode such that the solder material is in physical contact with the contact grid; re-heating the first body such that the solder material liquefies and is transferred from the first body to the second body; and soldering the solder material with the contact grid of the second body, including increasing the first thickness of the contact grid to a second thickness.
