English: An energy band diagram showing energy levels of layers in a typical SHJ (silicon heterojunction) solar cell. The diagram illustrates the contact selectivity of the doped amorphous layers, the difference in band gaps between layers (ie. the heterojunction), quantum tunneling (double arrows) and the degenerate semiconducting ITO.
The theoretical studies are of practical use because they predict the fundamental limits of a solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency. Band diagram of a solar cell, corresponding to very low current (horizontal Fermi level), very low voltage (metal valence bands at same height), and ...
A cross-sectional schematic of the layers of a bifacial silicon heterojunction solar cell An energy band diagram showing energy levels of layers in a typical SHJ solar cell A "front-junction" heterojunction solar cell is composed of a p–i–n–i–n -doped stack of silicon layers; the middle being an n -type crystalline silicon wafer and the ...

When constructing bulk-heterojunction solar cells, p-type nickel(II) oxide is an effective anode layer. Its function as a wide band-gap semiconductor helps planarize the anode surface, and helps maximum photon flux to reach the active layer. In this case, NiO thickness was also measured, and increasing the thickness decreases cell efficiency.

To understand how band structure changes relative to the Fermi level in real space, a band structure plot is often first simplified in the form of a band diagram. In a band diagram the vertical axis is energy while the horizontal axis represents real space. Horizontal lines represent energy levels, while blocks represent energy bands.
