In this work, three industry-related metallization approaches for silicon heterojunction (SHJ) solar cells are presented which are aiming for a reduction of silver consumption compared to conventional screen-printing of low-temperature silver pastes. The presented results are achieved on large-area cells (area of 244.3 cm 2).
Photovoltaic silver paste is applied to the surface of silicon solar cells through screen-printing, after which the paste is dried and sintered to form a grid electrode. Fig.1. Architecture of TOPCon solar cell on n-type monocrystalline silicon wafer.
The silver paste on the back side mainly plays the role of adhesion, and is mostly used on the backlit side of P-type cells. Therefore, the silver paste on the front side of photovoltaic panels requires a higher level of production process and electrical conductivity.
Good adhesion: photovoltaic silver paste can be firmly attached to the surface of the silicon wafer to ensure the reliability of the electrical connection. Anti-aging properties: after careful design, the photovoltaic silver paste can be used in the long-term to maintain stable electrical properties that are not easily affected by the environment.
From an economic and productivity perspective in the recovery of silver from solar cells, the chemical leaching presents a viable technique. At present, the predominant method for leaching is the utilization of nitric acid, succeeded by precipitation with either NaCl or NaOH or by electrochemical refining.
Silver paste is a key component in the production of silicon solar cells. The development of silicon solar cell technology has introduced new requirements and challenges for the front-side silver paste of solar cells.
Historically, the PV industry has demonstrated its great capability of reducing the silver consumption in screen-printed solar cells, where a factor of eight reduction in silver usage per cell has been achieved since 2010, mainly benefiting from the implementation of the multi-busbar technology and aggressive reductions in printed width of fingers.
