In the first design version of these solar cells, the heterojunction was formed by using the flat n-type crystalline silicon wafer with a thin layer of p-type amorphous hydrogenated silicon (a-Si:H) deposited on its surface . The efficiency of this structure reached 12.3%.
One of the main features of heterojunction silicon solar cells is passivation with a wide-gap semiconductor layer between the ohmic contacts and the active elements of the structure, which creates a high voltage when current flows through it; the voltage must be high enough to reduce the probability of recombination [14, 15].
Recently, the successful development of silicon heterojunction technology has significantly increased the power conversion efficiency (PCE) of crystalline silicon solar cells to 27.30%.

To achieve CO 2 neutrality, the future of our electricity supply will see a massive increase in solar power generation. The annual photovoltaic (PV) module production rate must dramatically increase from ∼135 GW (GW) in 2020 to ∼3 TW (TW) around 2030, and requires a total of 20–80 TW photovoltaics until 2050 and 80–170 TW until 2100 [[1], [2], [3]].
