The best efficiency was 22.56% with Al paste (25 wt%-29 wt% silicon). Screen-printing Ag paste on the rear side of the Tunnel Oxide Passivated Contact solar cells (TOPCon) is still the mainstream method to form electrodes. However, the high price of precious metals increases the cost of TOPCon cells.
Screen-printing Ag paste technology plays an important role in n-TOPCon solar cell. The energy density threshold of UV pulse laser ablate SiN x were investigated. The mechanism of Al paste and n + -poly-Si contacts was revealed. The best efficiency was 22.56% with Al paste (25 wt%-29 wt% silicon).
Front side silver paste: High conduction and good reaction to SiNx; the efficiency can be promoted about 0.2%. Photovoltaic Aluminum paste: Result a uniform BSF and strong combination to Si-wafer; the Voc and Isc were increased so that the efficiency can be promoted about 0.1% than other same commercial products.
In the future, the highest Eff of TOPCon solar cells printed with Al paste on the rear side are expected to reach the commercial TOPCon based on Ag paste, which applies laser doping selective emitter technology (SE) and bifacial poly-Si passivation structure. 1. Introduction
Screen-printing Ag paste on the rear side of the Tunnel Oxide Passivated Contact solar cells (TOPCon) is still the mainstream method to form electrodes. However, the high price of precious metals increases the cost of TOPCon cells. Al is a cheap and high-performance conductor, and its work function is compatible with the rear side of TOPCon cells.
The mechanism of Al paste and n + -poly-Si contacts was revealed. The best efficiency was 22.56% with Al paste (25 wt%-29 wt% silicon). Screen-printing Ag paste on the rear side of the Tunnel Oxide Passivated Contact solar cells (TOPCon) is still the mainstream method to form electrodes.
