A team of students from Sultan Qaboos University invented a technique by using graphene and polymer materials, as an alternative to silicon, to manufacture solar and photovoltaic cells. This method improves the efficiency of solar systems by up to 60 percent.The innovation was developed by students Aisha Al-Wahaibi, Mozn Al-Abrai, Al-Hasna Al-Adwani and Nusaiba Al-Kharousi from the College of Engineering at Sultan Qaboos University.The project aims to develop solar cells made of locally produced polyethylene and integrated with graphene, which is manufactured in the laboratories of Sultan Qaboos University.
