摘要： A solar cell module comprises a solar cell soldered to a mounting element, such as a ceramic substrate. The solder bond can comprise a void. A method of reducing a solder void comprises reflowing the solder using a vacuum source and a heat source in a sealed chamber. The chamber is formed, at least in part, by a cowling into which the solar cell module is mounted. A system for reducing voids in a solder bond comprises a heat source and a vacuum source coupled to the sealed chamber into which a solar cell module is placed. The system can optionally include a control system that automates the execution of methods of reducing solder voids. The system can further include a pressure source to aid in reducing the solder void and reflowing the solder after the void is reduced.

摘要： A solar cell module comprises a solar cell die that is soldered to a substrate. The substrate comprises one or more power contacts. A power conductor is soldered to a power contact, thereby electrically coupling the power conductor to the solar cell die. A pre-heat module heats a first side of the substrate at a first area to a first temperature for a first duration. Then, a solder heat source solders a power conductor to a power contact at a second area of the substrate at a second temperature for a second duration. The resulting solder connection at the power conductor is less prone to cold-solder defects. The temperature of the pre-heat module is controlled to promote curing of an RTV sealant used in the manufacture of the solar cell module. The temperature of the solder heat source is controlled to avoid burning and degrading of the RTV sealant.
