6 FAQs about [Heterojunction solar cell concept]

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%.

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 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.
