Today's industrial silicon solar cells often utilize dielectric surface passivation layers such as SiN x and Al 2 O 3. However, a passivation layer well-known from the microelectronic industry, SiO 2, had and has a strong impact on silicon photovoltaics.
The solar cell parameters Voc, Jsc, FF and Eff (ŋ) was studied w.r.t passivation layer (Fig. 2) by varying parameters such as thickness and band gap. By adding passivation layer in HIT Solar cell structure, efficiency increased by 1.1 percent (from 11.8 to 12.9 percent) with the passivation layer.
This study optimized the passivation layer on the front surface of N-type TOPCon solar cells to enhance the passivation effect, consequently further improving the conversion efficiency. We deposited a SiO x /AlO x /SiN x stack on the front surface of TOPCon solar cells.
It is fair to say that the passivation of the surfaces of silicon solar cells was THE enabler for achieving efficiencies greater than 20%. The first and most natural choice for surface passivation is a thermally grown SiO 2.
Concurrently, maintaining a thin passivation layer is essential for ensuring efficient carrier transport. With an ultrathin passivated contact structure, both Silicon Heterojunction (SHJ) cells and Tunnel Oxide Passivated Contact (TOPCon) solar cells achieve an efficiency surpassing 26%.
High-efficiency silicon solar cells strongly rely on an effective reduction of charge carrier recombination at their surfaces, i.e. surface passivation. Today's industrial silicon solar cells often utilize dielectric surface passivation layers such as SiN x and Al 2 O 3.

Uniform thickness is crucial, particularly in MIS solar cells, where thinner oxide regions can cause leakage currents that reduce open-circuit voltage and overall cell efficiency. Thinner oxide layers may also result in higher interface state density, while thicker layers could improve open-circuit voltage but potentially degrade fill-factor and short-circuit current density.
Hence the solution for passivation material for p + emitter is inevitable and as a consequence Al 2 O 3 emerged as outstanding material and a subject of significant research since in 2008, Schmidt et al. shown that the solar cell using Al 2 O 3 passivation layer results efficiency beyond 20% (Schmidt et al. 2008).
