Abstract Owing to its large work function, MoOX has been widely used for hole-selective contact in both thin film and crystalline silicon solar cells. In this work, thermally evaporated MoOX films are employed on the rear sides of p-type crystalline silicon (p-Si) solar cells, where the optical and electronic properties of the MoOX films as well as the corresponding device performances are investigated as a function of post-annealing treatment. The MoOX film annealed at 100oC shows the highest work function and proves the best hole selectivity based on the results of energy band simulation and contact resistivity measurements. The full rear p-Si/MoOX/Ag contacted solar cells demonstrate the best performance with an efficiency of 19.19%, which is the result of the combined influence of MoOX’s hole selectivity and passivation ability.

We investigated the effect of thermal annealing on the performances of Si solar cells. The Si solar cells were fabricated on p-type microtextured Si wafers using a standard cell fabrication process. The fabricated cells were annealed at 250 °C for 60, 80, and 90 min using a halogen lamp heater in N2 ambient. The annealed sample with a time of 60 min showed enhanced optical properties of light absorption, quantum efficiency, and minority carrier lifetime but did not show enhanced cell conversion efficiency. However, while the cell annealed for 90 min showed different optical properties, it showed the highest conversion efficiency of 17.35% compared to the reference cell of 17.14%, indicating the total recovery of the light soaking effect. We further analyzed the hydrogen-related chemical bonding structures for the dopant activation throughout hydrogen diffusion and the electroluminescence by a radiative recombination of a p–n junction.

The electronic properties of the solar cells were greatly influenced by the aluminum atomic concentration in Al-BSF region under that the Al-BSF is doped heavily. The effects of the dopincg profile in heavily-doped Al-BSF on electronic properties of n+pp+ monocrystalline solar cells were investigated by PC1D. The results show that the electronic properties of solar cells are almost independent of the doping profile of the Al-BSF, but are more or less affected by the BSF profile if the solar cell back surface is passivated well with the BSRV less than ~105cm/s. When the sheet resistance is about between 5 and 30Ω/□, the conversion efficiency can reach the maximum value. And the optimum thickness of Al-BSF is about between 10~15μm.
