“…Dow Corning reported papers and patents about a curing-type copper paste and the applicable solar cell structures [47][48][49][50][51]. The curing is referred to as the hardening of polymer materials by cross-linking polymer chains that can be processed by heating at a low temperature under 300°C.…”

In photovoltaic industries, the main technique of metallization is screen printing with silver pastes due to its simple and quick process. However, the expensive price of silver paste is one of the barriers to the production of low-cost solar cells. Therefore, the most focused target in photovoltaic research is the decreasing consumption of silver paste or substitute silver for other materials. As a proper candidate, copper has been researched by many institutes and companies since it has a similar conductivity with silver even though the price is inexpensive. To apply copper as a contact for solar cells, the plating technique has been actively researched. However, copper paste, which was mainly developed for integrated circuit applications, has been recently researched. Mostly, copper paste was developed for the low-temperature annealing process since copper tends to oxidize easily. On the other hand, firing type copper paste was also developed by coating copper particles with a barrier layer. This chapter discusses recent development of copper paste for the application of solar cells and its appropriate annealing conditions for better electrical properties. Also, the light I-V characteristics of copper paste on the solar cells in other research papers are summarized as well.

The 5 th Metallization Workshop took place in Constance, Germany on 20 and 21 October 2014 and provided an overview of research and development in the field of solar cell metallization. Enhanced understanding of contact structure and formation was obtained thanks to new characterization techniques. Great progress in metallization technologies was also reported. Screen printing technology is continuing its trajectory of continuous improvement, notably with fine-line screen printing (linewidth < 50 μm) becoming a reality. Ni/Cu plating technology is also progressing fast, with many of the technical barriers to adoption being successfully removed. Finally, the workshop also highlighted the move towards a module-centric design of solar cell metallization, targeting high performance and low cost at module level.

“…Silver has good electrical conductivity and is stable [5], [6], [7], [8]. To cut costs, however, copper is being considered as a candidate that can produce highly efficient solar energy at a low cost [9], [10], [11], [12]. Nevertheless, there are limitations.…”
