Can an electric field be applied to a silicon solar cell?
As the future work, the effect of an electric field in presence of a magnetic field both simultaneously applied to a silicon solar cell can be theoretically analyzed and experimentally evaluated.
Can field effect passivation reduce surface recombination losses in solar cells?
The first experimental attempts to reduce surface recombination losses in solar cells by means of the field effect passivation method were performed in the late 70s: Schwartz et al. investigated the impact of a gate voltage on the short circuit current Isc of an "interdigitated back contact" (IBC) concentrator cell.
What is the effect of magnetic field on silicon PV cells?
The influence of magnetic field was evaluated in theory using a proposed 3-D model [ 13 ]. It was shown that in theory, magnetic field impose a reduction in the cell's output power. Another model dealing with magnetic field effect on a bi-facial silicon PV cell was also reported [ 14 ].

The intensity of the magnetic field was in the range of 0.003 T–0.079 T, and it was observed that the cell's voltage is not affected by magnetic field.
