Effect of tunnel junction on the indium gallium nitride multi-junction tandem solar cell performances

A comparative study of two thienopyrimidine Schiff base probes for sequential monitoring of Ga3+ and Pd2+

“…Gallium, as a rare transition element, is found primarily as oxides in ores [1]. Its exceptional magnetic and thermal conductivity render gallium compounds extensively valuable for various industrial materials, including semiconductor film, multijunction solar cells, and catalysts for molecular transformation [2][3][4][5][6]. On the other hand, liquid gallium has attracted extensive attention because of its specific antibacterial activity and biocompatibility, finding wide application in treating hypercalcemia and bone metabolism [7,8].…”

The mixture was stirred overnight at ambient temperature, and the progress of the reaction was traced by TLC.…”

Effect of doping concentration of tunnel junction on I-V characteristics of photovoltaic power converter

“…Therefore, another design challenge for multi-junction photovoltaic cells is to ensure good conduction between sub-cells. In order to realize the low resistance connection between the sub-cells, a tunnel junction structure is usually used between two sub-cells [2,3,7]. Tunnel junction (TJ) is an ultrathin material with high doping concentration, a special (a) E-mail: 396175747@qq.com (b) E-mail: duchunhua@iphy.ac.cn (corresponding author) PN junction with tunnel effect.…”
