A comparative analysis of the development of electromagnetic pollution maps with artificial intelligence and interpolation

Cell phones and mobile devices have been an integral part of life over the past 30 years. In parallel with the intensity of use of mobile phones, the number of base stations has also increased. The increasing number of base stations has caused an intensity of electromagnetic pollution in the GSM band. The issue of electromagnetic pollution has become increasingly remarkable due to the claims that it can cause diseases...

Micro surface texturing formation in polycrystalline-silicon solar cells by means of CO2 laser

Surface texturing of polycrystalline silicon solar cells using a CO2 laser was achieved in the present study, with different line spacing and sizes in one dimension. The efficiency of the solar cell was calculated using the measurements of the short circuit current (ISC), the open circuit voltage (VOC), and the fill factor (FF). The SEM results showed the formation of micro-scale textures. Operational results showed...
