The peak temperature of furnace and the time of solar cells in furnace are variables that affect the solar cells sintering. In this paper, we choose three belt speed of sintering furnace: 235, 245, and 255 in/min.
The screen printing and rapid thermal processing [ 5 ], is a key process step in the fabrication of crystalline Si solar cells. In addition, the optical and electrical properties of the solar cells strongly depends upon the quality of the silkscreen, sintering temperature and belt speed, etc.
The so-called “selective sintering” means that the absorbed laser energy can effectively promote the electrical contacts between the TiO 2 nanoparticles, but does not cause damage to the plastic conductive substrate. The choice of the near-infrared (wavelength = 1064 nm) laser source is critical for the effectiveness of the laser sintering.
As an important part of the series resistance, the contact resistance depends on the behavior of the Ag/Si contact interface after the sintering process [ 15, 16 ]. In addition, the junction leakage and shunting characteristics are also heavily affected by the sintering process.
The solar cells that sintered with larger or lesser belt speed of sintering furnace possessed higher series resistances and smaller photoelectric conversion efficiency than those sintered with the best belt speed of sintering furnace.
In addition, the optical and electrical properties of the solar cells strongly depends upon the quality of the silkscreen, sintering temperature and belt speed, etc. The solar cell front side is commonly metallized by silver (Ag) front side metallization pastes.
As a result, the fabricated solar cell achieved a high open-circuit voltage, a high short-circuit current, and a low series resistance. Consequently, a power conversion efficiency of 19.94% was ...
With the increase in the use of crystalline silicon solar cells, it is necessary for solar cells to achieve finer and higher pre-metallization finger lines.

We found that, presence of Mercapto-Succinic Acid significantly affects short circuit current and thereby the overall efficiency of solar cell as it is insulating in nature. Sintering at 400 O C seems to help in increasing charge transfer from nanocrystals to TiO2.
As revealed from the comparison, the platinum counter electrode prepared by the vacuum coating method declined the short-circuit current of the cell because the resistance was overly large, and the performance of the DSSC was not enhanced. The platinum counter electrode obtained by the electrochemical method increased the maximum output power ...
