“…In order, to reduce the loss due to reflectance on silicon surface different methods have been used. Light trapping, surface texturing and anti-reflection coatings (ARC) etc are most widely used methods to reduce the loss due to reflection [1][2][3][4].…”

The aim of this work is to investigate the effect of anti-reflection coating to improve the performance of silicon solar cell. The reflectance for different anti-reflection coating materials (SLARC and DLARC) were calculated numerically as well as on online source of PV Education. The parameters of such materials are used in PC1D simulator to study the performance of solar cells. It was found that DLARC has considerable effect on the performance of solar cell as compare to SLARC. Further, it was observed that the photovoltaic efficiency and short circuit current is significantly high for SiO2/TiO2 DLARC.

“…16 The second was reacted vapor generated from the reaction of HF-HNO 3 -H 2 O solution and Si fragments. 17 The lab-scale reactor combines both vapors as the acid source for VTE. Initially, the experimental conditions were optimized in a small-scale experiment to find out the effect of acid vapor and reacted vapor on the VTE process.…”

In recent years, the low‐cost diamond‐wire (DW) slicing has been widely used for single‐crystalline silicon (sc‐Si) wafers, and this makes sc‐Si solar cells very attractive to the market. On the contrary, the adoption of DW slicing for multicrystalline (mc‐Si) wafers is troublesome because of poor texturing quality in the existing production lines using acid solutions. We have developed a vapor texture etching (VTE) process with the combination of both acid and reacted vapors for DW sliced mc‐Si wafers. The etching process was rather simple and low cost. More importantly, the acid usage was low and recyclable, so that the acid emission was low as well. Its scale‐up was easy and straightforward. In this lab‐scale reactor, more than 50 full‐size wafers could be processed each time. The etched wafers had uniform appearance and low reflectivity, around 10%. After the nanostructure pores were enlarged by post treatments to minimize surface recombination, the full‐size mc‐Si solar cell fabricated by Solartech could achieve an efficiency of 19.7% using the Passivated Emitter and Rear Contact (PERC) structure, which was comparable with the average production efficiency.

“…It should be pointed out that the VE of silicon using similar vapor sources has been intensively studied before for producing surface layers of nano-porous silicon [5,6], and by one group on multi-crystalline silicon wafers for nanometer-scale texturing on top of conventionally wet etched texture [7][8][9]. We experienced generation of nanostructured textures too, in our experimentations.…”
