Multicrystalline Silicon Passivation by Hydrogen and Oxygen- Rich Porous Silicon Layer for Photovoltaic Cells Applications

Autor: Aqeel Mohammed Hamoudi, Karim Choubani, Mohamed Ben Rabha

Publikováno v: Iranian Journal of Materials Science and Engineering, Vol 20, Iss 2, Pp 1-7 (2023)

In this work, we demonstrate the beneficial effect of introducing a superficial porous silicon layer on the electronic quality of multi-crystalline silicon for photovoltaic cell application. The porous silicon was formed using an acid vapor etching-b

Using the Log Mean Temperature Difference (LMTD) and ε-NTU Methods to Analyze Heat and Mass Transfer in Direct Contact Membrane Distillation

Autor: Mohammed A. Almeshaal, Karim Choubani

Publikováno v: Membranes, Vol 13, Iss 6, p 588 (2023)

In direct contact membrane distillation (DCMD), heat and mass transfers occur through the porous membrane. Any model developed for the DCMD process should therefore be able to describe the mass transport mechanism through the membrane, the temperatur
