Efficient and durable perovskite solar cell materials

Perovskite solar cells are attracting attention as the next-generation solar battery material thanks to their low processing cost and excellent photovoltaic quality. However, it is difficult to commercialize them because ...

Van der Waals junction spin valves without spacer layer

The fundamental principle of a spin valve is that the resistance is dependent on the parallel or antiparallel configurations of the two ferromagnetic electrodes, thus associating the magnetoresistance (MR) effect, whose basic ...
