Simulation of a novel junction-less solar cell structure using pc-1d software

Abstract EN

The continues demand for Photovoltaic device improvement has led us to search for new sources of photovoltaic action.

For that, this paper proves the existence of other sources for photovoltaic action in addition to the main source which is the built-in electrostatic field generated through controlled composition gradient Those new sources arc uncovered through mathematical examination of a specific material system followed by the construction of four-layer p-type semi-conducting materials (i.e., without pn-junction formation).

First three layers of this specific material system are fabricated with Al^Ga, tAs with different Aluminum fractions, while the fourth layer is fabricated with Ge with a diffused back surface field (BSF) layer to reduce surface recombination velocities (SRV).

The complete structure is analyzed using the PC-ID simulation software, and it shows that the junction- less structure possesses the photovoltaic action with low performance.
