Title:
SOLAR CELL USING ALUMINUM-DOPED TITANIUM DIOXIDE AS ELECTRON EXTRACTION LAYER
Document Type and Number:
WIPO Patent Application WO/2022/215804
Kind Code:
A1
Abstract:
Solar cells according to the present invention are an organic solar cell (OSC) and an inorganic-organic hybrid perovskite solar cell (PeSC) that include an electron extraction layer (EEL) made of titanium dioxide (TiO2) and use the photovoltaic effect, wherein the electron extraction layer is doped with aluminum (Al). Accordingly, the photovoltaic performance of the solar cells is improved due to surface flattening of the electron extraction layer and a decrease in activation energy.
