English term or phrase: a shadow junction
Este es un ensayo sobre la energía solar y este párrafo habla sobre las células solares. Estoy teniendo dificultad con el término "a shadow junction".
El párrafo completo dice así:

Phosphorus, which has 5 valence electrons, is a donor and causes extra electrons to appear in the conduction band. Silicon so doped is called "n-type". On the other hand, boron, with a valence of 3, is an acceptor, leaving so-called "holes" in the lattice, which act like positive charges and render the silicon "p-type". Holes, like electrons, will remove under the influence of an applied voltage but, as the mechanism of their movement is valence electron substitution from atom to atom, they are less mobile than the free conduction electrons. In a n-on-p crystalline silicon solar cell, a SHADOW JUNCTION is formed by diffusing phosphorus into a boron-based base.
