This article investigates thermal laser separation (TLS) on p-type Czochralski-grown silicon (Cz-Si) passivated emitter and rear cells (PERC) n-type Cz-Si heterojunction (SHJ) solar cells. The TLS comprises of two laser-based processes: the crack initiation by a scribe propagation cleave process leading to separated with smooth edge surfaces. sole impact cells' passivation layers is examined performing it without initial scribe, not separating samples. By means photoluminescence imaging,...
The development of functional field emission based pressure microsensors is reported. fabrication and both electrical mechanical parts the sensor device are investigated; these cold cathode emitters sensing membranes, respectively. In order to avoid expensive process runs optimize design meet requirements, simulation work was performed using commercially available FEMLAB package software. Realistic characteristics from sulfur doped boron nitride (S-BN) were used model current density...
In this paper, a new type of self-organized Si micro-tip arrays was designed by introducing gold coating during laser-assisted ablation wafers in vacuum to improve the emission properties arrays. The results showed that typical current limit for Si/Au improved compared with recently studied or Ni micro-arrays. On other hand, macroscopic surface uniformity tips height and sharpness is not sufficient achieve perfect So future improvement could be made incorporation carbon nanotubes into layer...
