Sanyo (Japan) started introducing heterojunction solar cells with a-Si/c-Si structure of such structure in the 1980s. The manufactured devices consisted of n-type silicon wafers and emitters made of p-type conductivity amorphous silicon doped with boron. These solar cells had an efficiency of about 12%.
In accordance with the data presented, possibilities were found to increase the output characteristics by improving the design of the contact grid of solar cells and modifying the structure of heterojunction solar cells.
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].
Silicon heterojunction devices rely on the use of thin‐film silicon coatings on either side of the wafer to provide surface passivation and charge carrier‐selectivity. Beyond traditional indium tin oxide, multiple higher‐mobility indium‐based transparent conductive oxides have been employed successfully in HJT cells.
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%.
The indium usage of the 27.09% efficiency record cell is only 1/5 of that of traditional bifacial heterojunction solar cells. “Innovation is the core competitiveness of enterprises and LONGi is committed to 'making the best of solar energy to build a green world'.
