An Extendible Beyond 20% Efficiency cost-Efficient Bifacial Cell Using Boron & Phosphorus Implantation Technology and Its Prospects for the Future Production. : Haibing Huang, Jun Lv, Lichun Wang, JianBo Wang, Weicheng Zhu, Lisa Mandrelt, Jim Sullivan, Babak Adibi, Chris Smith, Hannu Laine, Hele Savin.The loss mechanisms of cell efficiency and recombination are analyzed based on key characterizations combined with PC1D/PC2D simulations, and effective solutions are put forward to decrease these losses and thus to increase cell efficiency. The key processes of Al2O3 passivation and screen-printing aluminium local back surface field, as well as integration of the entire PERC process are discussed, based on which a cost-efficient industrial PERC roadmap is presented. To achive this, a systematic study is needed on both PERC and PERT cells from an industrial research perspective, which is the aim of this thesis.The first part of the thesis studies the industrial PERC cell. In p-type c-Si solar cells, industrial PERC (Passivated Emitter and Rear Cell) and PERT (Passivated Emitter and Rear Totally-diffused) cells are two potential candidates towards even higher cost-efficiency. At present, p-type crystalline silicon (c-Si) solar cell is the mainstream cell product in PV industry due to cost-efficiency. As photovoltaic (PV) energy will gradually become one of the main renewable energy sources to replace conventional energy sources in the next decades, industry needs to pay attention to mass production of cost-efficient solar cells.

By optimizing the effective parameters, a 20.35% efficient solar cell has been achieved by simulation. An anti-reflection coating with 2.019 refractive index and a thickness of 74 nm is considered as optimum. From the simulation it is seen that the optimum value of p-type doping concentration is \(1\times 10^\) and equal angles of 54.74 degrees produces the best result in simulation. It is seen that the textured surface reduces reflection and increases the efficiency of the solar cell at least 1–2%. To optimize the simulation experimentally obtained data has been used in the texturization process. For a p-type monocrystalline silicon wafer, with an area of \(10\times 10\) cm 2 and a thickness of 300 μm, initial simulation shows a 12.10% efficient solar cell. The impact of different solar cell parameters, with their effects on power and efficiency, has been investigated. In this paper, simulation of a monocrystalline silicon solar cell was done using PC1D software.
