Single-crystal silicon solar cell efficiency increase in magnetic field

It is established in experiment that efficiency of unijunction (UJ) single-crystal silicon solar cells (Si-SC) with horizontal n(+)-p-p(+) diode structure may increase by a factor of approximately 1.1 after their holding at room temperature during 7 days in perpendicularly oriented stationary magnetic field with 0.2 T induction. The subsequent stabilizing of the obtained positive effect is shown to be realizable by attachment of a thin magnetic vinyl layer (creating in the UJ Si-SC base crystal a magnetic field with induction not exceeding 0.05 T) to the UJ Si-SC at the back electrode side.
