محتوى المقالة الرئيسي
الملخص
تتم تحضير أغشية رقيقة من البلورات النانويةSn1-xCdxS (x=0,0.7, and 1) بسماكات مختلفة (200، 300، 400) نانومتر على قواعد زجاجية عند درجة حرارة 300 درجة مئوية بطريقة المشاركة وطريقة الانحلال الحراري بالرش الكيميائي (CSP). تمت دراسة تأثير تركيز Sn والسمك على الخصائص التركيبية والبصرية للأغشية المحضرة. تم توصيف الأغشية لتقييم البنية والنفاذية وفجوة نطاق الطاقة الضوئية. أظهرت دراسات حيود الأشعة السينية (XRD) أن الأفلام كانت متعددة البلورات ذات هياكل سداسية ومتعامدة. أظهرت نتائج الأشعة السينية وقياس القوة الذرية أن حجم الحبيبات يزداد مع سمكها. تم تحديد طاقات فجوة النطاق البصري ونوع الانتقال والامتصاص البصري للأغشية من أطياف النفاذية البصرية. أظهرت دراسات الامتصاص البصري في مدى الطول الموجي (200-1100 نانومتر) أن قيم طاقة فجوة الطاقة للأغشية تتناقص من (2.48-1.95)الكترون فولت، (2.41-1.92)الكترون فولت، و(2.3- 1.89) الكترون \فولت مع زيادة تركيز القصدير ومع زيادة السمك (300,200، 400) نانومتر على التوالي. تم تحديد أفضل خواص للمادة المحضرة لإمكانية استخدامها في صناعة الخلايا الشمسية.
