“…Since then, using the same device architectures there has been a significant development in the materials performances as in the case of the silver pastes that have led to a remarkable improvement of the grids with better aspect ratios, very thin fingers and optimized antireflection coatings. [36][37][38][39][40][41] It has taken about 30 years to obtain commercial solar cells with the efficiency levels originally obtained in the research laboratories. In the last few years, there have been revolutionary changes in the architecture of the crystalline silicon modules thanks to the introduction of more sophisticated assembly schemes.…”

Solar cells cost per Watt has decreased so quickly in the last years that photovoltaic (PV) module manufacturing costs cover only a small fraction of the total costs of a PV plant. Essentially, the installation and operation costs as well as the costs for the management of starting materials are the main factors today the most important levers for total costs decrease. PV technology has advanced towards both efficiency and average energy generation increasing by light capture optimization and losses minimization. This work analyses the state-of-the-art of PV technology for terrestrial application and discusses the perspectives for future development, which aims at overwhelming limitation posed by material properties. Higher focus is given to the most promising current technology such as silicon heterojunction solar cells and on future developments based on tandem cell approaches.

“…In the case of thinner silicon solar cells, the front surface is textured to increase light absorption via multiple reflection. It was reported that solar cells that have an n-type emitter thickness of less than 1 µm feature a better surface quality compared to a p-type emitter in terms of absorbing the maximum light [10,11]. In addition, the front metallization design of solar cells is very important in order to obtain the maximum output power from the cells.…”

“…Metallization designs have also been studied, using simulation methodologies to evaluate the solar cell performance. Siraj et al [11] conducted simulation research using Griddler software to assess the influence of the front and rear metallization pattern of crystalline silicon solar cells. They compared the efficiency, fill factor (FF), short-circuit current (Isc), and open-circuit voltage (Voc) parameters for 80-120 metal fingers with a width of 60 and 1-5 metal busbars.…”

Using Griddler software, this study aims to select the optimal metallization design by analyzing the impact of the number and sizes of busbars and fingers on a solar cell’s performance. There is interest in the PV industry to reduce the finger size toward 25 μm in upcoming years. It is shown that an increase in the number and size of busbars and fingers causes an increase in the fill factor; however, with regards to the cell’s efficiency, the shading factor should be considered in addition to the size and number of metal contacts. The results of this study indicate that solar cells’ efficiency could be increased by 0.33–0.84% when using five busbars and a finger width of 35 μm. Moreover, this increase is achieved by reducing the emitter resistance to less than 60 ohm/sq and considering a recombination rate of about 165 fA/cm2.

In this paper, the effects of particle size difference of aluminum (Al) powder on physical properties of Al powder and sintering properties of Al paste were investigated. For this purpose, respectively, Al powders with four mean particle sizes were used, which were obtained by two classifications using the same nitrogen atomization process. Thermal analysis results showed that the smaller the Al particle size, the lower the oxidation temperature and the higher the reaction enthalpy, indicating higher reactivity of the Al powder. Four Al powders were prepared into Al paste by the same process, and the resistances of the paste increased with the decrease of the particle size of the aluminum powder. Electrochemical capacitance-voltage profiler (ECV) and scanning electron microscope (SEM) analysis showed that the smaller the Al particle size, the thicker the back surface field (BSF) and the higher the doping concentration of BSF. It was found that the smaller size of Al powder limited the migration of silicon, which resulted in higher concentration of silicon (Si) in the Al-Si liquid phase. This leads to reaching a balance at a higher temperature between the recrystallization of silicon from the alloy liquid and the dissolution of silicon in the liquid alloy and a higher doping concentration and a higher effective BSF doping thickness. Results of the study will provide reference for further study and application of Al paste.
