A tunnel junction structure comprises an n-type tunnel junction layer of a first semiconductor material, a p-type tunnel junction layer of a second semiconductor material and a tunnel junction between the tunnel junction layers. The first semiconductor material includes gallium (Ga), nitrogen (N), arsenic (As) and is doped with a Group VI dopant. The probability of tunneling is significantly increased, and the voltage drop across the tunnel junction is consequently decreased, by forming the tunnel junction structure of materials having a reduced difference between the valence band energy of the material of the p-type tunnel junction layer and the conduction band energy of the n-type tunnel junction layer. Doping the first semiconductor material n-type with a Group VI dopant maximizes the doping concentration in the first semiconductor material, thus further improving the probability of tunneling.

The invention discloses a photovoltaic encapsulation material EVA adhesive film resisting potential induced attenuation. EVA with the VA content being 8 to 21wt percent and low-density polyethylene orvinyl copolymer with the melting rang being 70 to 130 DEG C are mixed into matrix resin; then the matrix resin, complex absorbing sodium ion and other assistants are subjected to premixing, melt extrusion, casting and film formation, cooling, slitting and rolling processes, so that the adhesive film is formed. The ion mobility is reduced through proper reducing of the VA content, the improvementof the volume resistivity of the EVA adhesive film and the reducing of the content of acetic acid in a photovoltaic system from the source. The volume resistivity of the EVA adhesive film is improvedthrough the adding of the high-melting polyethylene or vinyl copolymer, and meanwhile water vapor transmittance is reduced. Environment of sodium ion on the surface of a battery is reduced through theadding of the complex absorbing sodium ion, passivation phenomenon caused in a battery piece antireflection layer is weakened or even eliminated, and the potential induced attenuation resistance of the adhesive film is improved.
