Indium Tin Oxide is the preferred material for the transparent conductive oxide (TCO) layer of the heterojunction solar cell, but researchers are investigating using indium-free materials that will reduce costs for this layer. The reflectivity and conductivity properties of ITO make it a better contact and external layer for the HJT solar cell.
There are two varieties of c-Si, polycrystalline and monocrystalline silicon, but monocrystalline is the only one considered for HJT solar cells since it has a higher purity and therefore more efficient. Amorphous silicon is used in thin-film PV technology and is the second most important material for manufacturing heterojunction solar cells.
But the emitter of HJT solar cells is amorphous silicon, so TCO films should be introduced between the amorphous silicon layer and the metal electrode to ensure the lateral transmission of current and reduce the disadvantage of high heat loss caused by poor lateral transmission performance of conventional solar cells.
In conclusion, HJT solar cells has excellent optoelectronic properties when the oxygen content is 2.2%. The average efficiency of the back side of the cells is 19.95%, and the average bifacial ratio reached 84.75%. 3.2.
Heterojunction solar cells (HJT), variously known as Silicon heterojunctions (SHJ) or Heterojunction with Intrinsic Thin Layer (HIT), are a family of photovoltaic cell technologies based on a heterojunction formed between semiconductors with dissimilar band gaps.
Standard (homojunction) solar cells are manufactured with c-Si for the n-type and p-type layers of the absorbing layer. HJT technology, instead, combines wafer-based PV technology (standard) with thin-film technology, providing heterojunction solar cells with their best features.
