  2. 21. Interfacial Analysis and Charge Transfer in Solar Cells

    Author : Xinjian Geng; Jacinto Sá; Ellen Moons; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perovskites; Charge Transport Layer; Plasmonics; Hot Carriers; Interfaces; Photoluminescence; Solar Cells; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : Harnessing sunlight through solar cells is vital for sustainable energy production. The conventional architecture of a solar cell consists of multilayers of materials, each serving a particular function. The absorbing layer converts the solar energy into valuable electricity by the photovoltaic effect. READ MORE
