Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so. The rear surface passivation by a localized dielectric layer for high efficiency silicon solar cells has significant advantages compared with the standard fully covered metal back-contact structure. In this study, partial borosilicate glass (BSG) layer used as rear dielectric passivation of localized back contacts was taken advantage for a local back surface fi eld (LBSF) solar cell, while typically it has been removed after thermal diffusion process fi nished. A simplified flash foam stamping technique has been initially exploited in the single-step process to pattern a localized back BSG passivation. These low cost, simple technique and scalable process have to be considered promising in the high efficiency of commercial solar cells. Acid stamp narrowly removes BSG in order to open the contact area between metal and p-Si substrate. The aperture ratio of the BSG pattern is varied from 5 - 20%. The LBSF solar cell with a localized back BSG passivation showed an increase in open voltage, fi ll factor and power conversion efficiency by 4.88%, 1.43%, and 0.67%, respectively, compared to a sample without LBSF layer. Therefore, this non-complex process using flash foam stamp is an alternative production procedure to have co-operated effectively with solar cell industrial production for power efficiency improvement. 2020-10-08T08:36:16Z 2020-10-08T08:36:16Z 2020 Chiang Mai Journal of Science 47,4 (Special Issue II : July 2020), p.614-623 2465-3845 https://epg.science.cmu.ac.th/ejournal/dl.php?journal_id=11090 http://cmuir.cmu.ac.th/jspui/handle/6653943832/69878 Eng Faculty of Science, Chiang Mai University
