An organic light emitting structure employs alkaline-earth metal between a cathode and an electron-transport layer. Such a structure may improve degraded luminescence of light emitting structure and enhance stability of element operation.
Abstract:
A thin film solar cell includes a substrate, a transparent electrode layer, a semiconductor layer, a back electrode layer, a positive electrode and a negative electrode. The semiconductor layer is formed on the transparent electrode layer and has grooves. The back electrode layer is formed on the semiconductor layer, in which formation of the semiconductor layer with the back electrode layer is patterned and the patterned formation with the transparent electrode layer form unit cells connected in series. The positive electrode is formed upon a front unit cell of the unit cells. The negative electrode is formed upon a last unit cell of the unit cells. The back electrode layer is formed to fill at least the grooves of the front unit cell and the last unit cell to directly connect with the transparent electrode layer. A method for fabricating a thin film solar cell is also provided.
