Sebastian Tepner and Andreas Lorenz contributed equally to this work. This paper presents a comprehensive overview on printing technologies for metallization of solar cells. Throughout the last 30 years, flatbed screen printing has established itself as the predominant metallization process for the mass production of silicon solar cells.
A successful application of this printing method for the metallization of heterojunction solar cells has been demonstrated. 369 First attempts to use rotary screen printing for the metallization of silicon solar cells date back to the late 1990s 362 but have not been pursued further.
Screen-printed solar cells were first developed in the 1970's. As such, they are the best established, most mature solar cell fabrication technology, and screen-printed solar cells currently dominate the market for terrestrial photovoltaic modules. The key advantage of screen-printing is the relative simplicity of the process.
Beside screen printing, multi-nozzle dispensing, and rotary printing, further printing and coating technologies to apply the front and/or rear side metallization of silicon solar cells have been investigated in the last decades. Several studies investigated the application of the front side grid using inkjet technology.
Surface texturing for suppressing the reflection losses is the first and foremost step in the solar cell fabrication process. Over the years, multi-crystalline silicon (mc-Si) wafer solar cells dominated the PV market due to their cost-effectiveness.
Screen-printing provides an economically attractive way for making Ag front electrode grid lines of Si solar cells, and the morphology, uniformity, height, and width of grid lines by screen-printing are important for electrical performance of solar cells.
