A team of German researchers has developed a miniaturized solar cell experiment for nanosatellites. It was used to test ...

Tight junctions are a type of cell-cell junction found in epithelia that forms a barrier that is impermeable to the majority of soluble molecules between the two sides of the epithelium.

The novel cell technology was introduced in the paper “24.2% efficient POLO back junction solar cell with an AlO x /SiN y dielectric stack from an industrial-scale direct plasma-enhanced ...

Once the bottom layer has gained extra electrons, it becomes negatively charged at the junction; at the same time, the top layer has gained a positive charge there. Now the cell is ready for the sun.

A solar cell consists of a layer of p-type silicon placed next to a layer of n-type silicon (Fig. 1). In the n-type layer, there is an excess of electrons, and in the p-type layer, there is an excess ...
