“…In addition, the PbO-containing glass powder demonstrates favorable wettability with various battery base materials. This property ensures that the formed silver film exhibits better adhesion to the base, and simultaneously, it can more effectively, etch the ARC (Yuce et al, 2019;Hui et al, 2020). However, the extensive use of lead poses The infrared absorption spectrums of glass powders with different contents of GeO 2 added.…”

The Te-based glass powder exhibits distinctive characteristics such as a low melting temperature and high chemical stability, rendering it a focal point of research in the realm of glass powder applications for solar cells. In this investigation, a pioneering Ge-containing Te-based lead-free glass powder was synthesized, and the influence of GeO2 content on critical parameters such as glass transition temperature (Tg), high-temperature fluidity, high-temperature wettability, acid and alkali resistance, as well as the network structure of the glass, was systematically explored. At an optimal GeO2 content of 8%, the glass powder displayed the lowest Tg (437°C), accompanied by a subdued crystallization reaction. The high-temperature fluidity and wettability exhibited favorable characteristics, indicating that the inclusion of GeO2 in the glass powder resulted in an enhanced interface contact. Building upon this foundation, techniques to augment the Ag+ content within the glass powder were investigated, along with the interaction between Ag+ and the SiNx anti-reflection layer or silicon on the surface of crystalline silicon solar cells. It was discerned that the Ag+ content in the glass powder significantly influences the deposition of silver microcrystals on the surface of crystalline silicon, thereby impacting the contact resistance of the solar cell. Then influences the series resistance and photoelectric conversion efficiency of the solar cell.

“…Firstly, the silver particles undergo mutual sintering, forming conductive paths and densification [19,20]. Secondly, the glass powder softens, melts, and flows onto the silicon layer, establishing the interface connection between the silver electrode and the silicon solar cell [21][22][23][24][25]. The former process determines the resistivity of the silver electrode post-sintering, requiring close packing of silver particles and high sintering activity.…”

Silver powder, as the primary component of solar silver paste, significantly influences various aspects of paste performance, including printing, sintering, and conductivity. Silver powders prepared using the liquid-phase reduction method exhibit different microstructures depending on whether the growth process is dominated by aggregation or crystalline growth. This study explores the impact of different silver powder microstructures on packing density and sintering activity. It is observed that polycrystalline aggregated silver powder possesses higher surface energy, lower packing density, and greater sintering activity. Investigation into the influence of different silver powders on the electrical conductivity, adhesion, and structural density of silver paste reveals that polycrystalline aggregated silver powder is more suitable for lower sintering temperature pastes, whereas crystalline growth-type silver powder is better suited for higher sintering temperature pastes, resulting in a denser sintered silver layer. Finally, an analysis of the impact of various silver powders on the aspect ratio and electrical performance of solar cell silver grid lines yields higher aspect ratios (0.40) and photoelectric conversion efficiency (19.26%).

The efficiency of silicon solar cells is largely affected by the quality of the front and back metallic contacts. In this work, MoO3 is added to the Al paste for the back contact of crystalline silicon solar cells. The MoO3 additive lowers the series resistance of the solar cell from 4.1 to 3.5 mΩ and increases the photoelectric conversion efficiency from 19.26 to 19.54%. We identify that the thermite reaction between MoO3 and Al takes place at about 800 °C and metallic Mo diffuses into the Al–Si solid layer, decreasing the barrier height between Al and Si and lowering the contact resistance. This work demonstrates an approach by optimizing the aluminum-back surface field (Al-BSF) in the back metallic contact of crystalline silicon solar cells to enhance the performance of the cell.
