However, one of the most significant steps made for creation of new high-efficiency HJT structure solar cells was the idea of the using of the intrinsic conductivity a-Si:H as a buffer layer between the doped emitter and the silicon wafer which led to reduction of the dangling bond densities and densities of defects at the interface.

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].
In summary, C/Si HJ solar cells provide an avenue towards low-cost but high efficiency photovoltaics. However, due to the inhomogeneities of the carbon-based film during fabrication and the lack of interface passivation, the PCE and active areas are lower than C/Si solar cells.
