How do solar cells form a heterojunction?
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%.
Can heterojunction solar cells improve the output characteristics?
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.
What is a heterojunction silicon solar cell?
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].
Can silicon heterojunction solar cells improve power conversion efficiency?
Silicon heterojunction (SHJ) solar cells have reached high power conversion efficiency owing to their effective passivating contact structures. Improvements in the optoelectronic properties of these contacts can enable higher device efficiency, thus further consolidating the commercial potential of SHJ technology.
When did Sanyo start introducing heterojunction solar cells?
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%.
What are amorphous silicon-based silicon heterojunction solar cells?
Among PC technologies, amorphous silicon-based silicon heterojunction (SHJ) solar cells have established the world record power conversion efficiency for single-junction c-Si PV. Due to their excellent performance and simple design, they are also the preferred bottom cell technology for perovskite/silicon tandems.
