Dec 25, 2023 · Potential-induced degradation (PID) may be a serious concern in photovoltaic (PV) modules and plants, particularly when approaching high system voltages (1500+ V).
Heterojunction solar panels work similarly to other PV modules, under the photovoltaic effect, with the main difference that this technology uses three layers of absorbing materials combining thin-film and traditional photovoltaic technologies.
In a bulk heterojunction, the donor–acceptor interface is highly folded such that photogenerated excitons find an interface within a distance LD of their generation site. Currently, state-of-the-art bulk heterojunction polymer photovoltaic cells have power conversion efficiencies of up to 3.5% (refs 7–9 ).
There are several steps involved in the manufacturing process of the heterojunction solar cell. These are the following: The wafer processing involves cutting the c-Si cells with a diamond-based saw. Performing this process with extreme delicacy will result in high-quality c-Si layers, which translates to higher efficiency.
Recently, the successful development of silicon heterojunction technology has significantly increased the power conversion efficiency (PCE) of crystalline silicon solar cells to 27.30%.
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.

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.
