“…The etching is the standard procedure adopted to eradicate edge shunts and sawing defects. Researchers have investigated the effect of etching on the deformation of micro-cracks and found that neither alkaline, nor acidic etching had a significant effect on the length of the crack [36][37][38]. However, the depth of the crack was reduced since the silicon material was washed away from the edges of the crack.…”

“…Furthermore, the etching duration also has a significant effect on the stability of the solar wafer. The duration of etching significantly reduces the material thickness, thereby resulting in a fragile wafer which is prone to subsequent cracking [36][37][38][39][40][41]. Kim et al [36], Xianfang et al [32] and Schneider et al [41] reported that mechanical edge isolation and etching processes resulted in ∼10-25% reduction in mechanical durability of the solar wafer.…”

Renewable energy is going to play an immensely important role in the coming decades. Hence, the bulk manufacturing of solar panels has seen a renewed interest. For this purpose, it is imperatively important to assess the techniques that can be employed on automated production lines for evaluating the quality of solar wafers and cells. To-date many non-destructive testing methods to access the micro-defects in solar wafers and cells have been developed around the globe; however, not all of them can be applied on a fast-paced production line. In this regard, this study details all the nondestructive evaluating techniques that can be employed on an automated production line. Using a multi-attribute decisionmaking method, a strategic evaluation procedure is developed that can be adopted for the optimum selection of evaluation tools currently available in the market. This study is aimed at young researchers, graduate students and practitioners who want to come up-to-speed regarding the various defects that occur in solar wafers and cells along with the techniques that are currently being adopted to evaluate those defects. Also, future trends in research are highlighted regarding the development of assessment techniques.

“…The starting wafers were commercial PV-grade 156 × 156 mm 2 cast mono-Si with the resistivity of approximately 3 Ωcm, thickness of 180 µm and <100> orientation. After diamondwire sawing the wafers from the ingot, the wafer surfaces had experienced the PV industry-standard alkaline-based saw damage etching [15]. Such etching results in a slightly rough surface as seen in the scanning electron microscope (SEM) image in Fig.…”

Casted silicon wafers dominate the current photovoltaic (PV) market due to much lower fabrication costs as compared to well-known Czochralski (Cz)-growth. Traditionally casted silicon ingots have been multicrystalline, but recent developments in casting technology have enabled also the growth of single crystalline (sc) silicon ingots. While the resulting sc-Si ingot quality is naturally high enough for PV, it is not sufficient for the integrated circuit (IC) industry, mainly due to the increased amount of intrinsic point defects and dislocations in comparison to Cz-Si. However, many applications that do not have such stringent requirements for substrates, such as microand nano-electromechanical systems (MEMS, NEMS), could potentially find this material beneficial. Indeed, here we take the first step in studying the applicability of cast mono-Si for such applications. More specifically, we focus on advanced focused ion beam lithography combined with deep reactive ion etching for NEMS and wet etching for MEMS. Our results show that the quality of cast monoSi is high enough for successful patterning in both micro-and nanoscale. Sub-micron resolution is achieved and the Ga + doses required for successful patterning are comparable to conventional Cz-Si. The preliminary results presented here thus show great promise for cast mono-Si as a low-cost alternative for micro-and nanoelectromechanical systems.

To date, because of solar energy storage coupled with nanomaterials, surface engineering has become an essentially critical method for functional electrode design. Despite years of research on nanoscale materials for energy storage, commercial batteries still make use of microscale materials for electrodes. This is due to a combination of manufacturing challenges for nanoscale materials and the reactive nature of nanoscale materials that leads to high irreversible capacities associated with solid electrolyte interphase formation.Surface texturing is a powerful tool to decouple bulk material properties from surface characteristics that often bottleneck energy storage applications of nanomaterials and has been successfully used to improve the efficiency of photo detectors and solar cells due to a reduction in reflections at the surface. Therefore, the simple wet acid surface texturing methods for green energy-silicon solar energy are reviewed with the aim to provide the vital information about the growing field in surface engineering of solar energy with environmental friendly nature.
