“…As the p-doped surfaces are lowly doped, the specific resistivity is higher though it stays under the crucial limit of 0.01 Ω cm 2 . As a low-cost approach, Chena et al [88] applied the aluminum electrodes deposited by e-beam evaporation using Al contact for high performance IBC cells. The specific contact resistivity of the Al contact cell resulted in 0.7 and 0.05 mΩ cm 2 on an n-doped and p-doped surface, respectively, and the final Al-contacted IBC cell resulted in an efficiency of 22.72%.…”

Solar cell market is led by silicon photovoltaics and holds around 92% of the total market. Silicon solar cell fabrication process involves several critical steps which affects cell efficiency to large extent. This includes surface texturization, diffusion, antireflective coatings, and contact metallization. Among the critical processes, metallization is more significant. By optimizing contact metallization, electrical and optical losses of the solar cells can be reduced or controlled. Conventional and advanced silicon solar cell processes are discussed briefly. Subsequently, different metallization technologies used for front contacts in conventional silicon solar cells such as screen printing and nickel/copper plating are reviewed in detail. Rear metallization is important to improve efficiency in passivated emitter rear contact cells and interdigitated back contact cells. Current models on local Al contact formation in passivated emitter rear contact (PERC) cells are reviewed, and the influence of process parameters on the formation of local Al contacts is discussed. Also, the contact mechanism and the influence of metal contacts in interdigitated back contact (IBC) cells are reviewed briefly. The research highlights on metallization of conventional screen printed solar cells are compared with PERC and IBC cells.

“…Hence, several types of materials, methodology and geometrical structure have been introduced to form the back surface in order to improve the cell efficiency by researchers over the years [20][21][22][23]. In recent years, another potential cheaper contact-forming technique, deposition by evaporation, has been attempted that can replace fired silver/aluminum paste screen printed deposition forming the required thickness of back surface contact within very short time having advantages of good ohmic contact [6][17] [24][25]. However, the impact of other materials as BSF with different metals having different work-functions by thermal evaporation method is yet to be studied thoroughly.…”

This paper presents comparison of thermal evaporation method based passivation and BSF formation with different materials (Au, Al, and Cu). Silicon solar cells with different rear surface contact using these materials were fabricated. A comprehensive comparison of the samples have been carried out to find better back surface contact regarding the efficiency by investigating I-V characteristics, fill factor, external quantum efficiency and carrier diffusion length and lifetime, etc. Experimental data revealed that Cu based back surface contact has maximum output efficiency of about 13.73%, whereas Au shows maximum external quantum efficiency of about 86%. Moreover, use of Al shows the maximum carrier diffusion length 97.2μm and highest carrier lifetime of 3.5μs with overall cell efficiency of 12.90% indicating that Al is a promising material for back contact for n +-p-p + back surface field silicon solar cell.

ARTICLE INFO ABSTRACTArticle history:In this research, a continuous roll-to-roll screen printing system was developed using a flat screen. It has a newly devised sliding mechanism of screen printing module, which can be controlled accurately in sync with a moving web, driven by a roll-to-roll tension control and web-guiding system. In addition, the real-time precision alignment module that consists of a vision camera and an X-Y-θ alignment stage was implemented. With this developed system, the feasibility of continuous printing with minimum pattern width below 60 µm was verified, and an overlay of ±60 µm between the laser-patterned reference mark and the printed mark on a 300-mm-wide film was achieved. , NFC 태그 [5,6] , 스마트 센서 [7] 등 다양한 분야에 활용되고 있다. 현 재까지 스크린 인쇄는 단독 구동방식의 평판 스크린 타입의 장비가 주를 이루며 [1][2][3][4][5][6][7][8] , 유연전자 제품에 적용하기 위한 롤투롤(roll-toroll) 형태의 스크린 인쇄 장비도 개발되어 활용되고 있다 [9][10][11] .
