Hence, today the surface passivation of silicon solar cells by Al 2 O 3 is considered a key technology in future industrial high-efficiency solar cell production. The first study of the surface passivation properties of Al 2 O 3 on silicon was in fact already published in 1989 by Hezel and Jaeger .
An efficiency (22.01%) of MoO x -based crystalline silicon solar cells Effective surface passivation is pivotal for achieving high performance in crystalline silicon (c -Si) solar cells. However, many passivation techniques in solar cells involve high temperatures and cost.
To further promote the surface passivation and hole selectivity of the rear contact for high-performance p -Si solar cells, an additional ultrathin Al 2 O 3 film was employed as the passivation interlayer.
To introduce a passivation layer, a PEAI salt solution was spin-coated onto the perovskite surface. It is noted that no additional process was carried out for PEAI layer. The device structure of the perovskite solar cells we adopted in this study is shown in Fig. 1a.
The first study of the surface passivation properties of Al 2 O 3 on silicon was in fact already published in 1989 by Hezel and Jaeger . They used the relatively simple deposition technique of atmospheric pressure chemical vapour deposition (APCVD) and demonstrated a very good level of surface passivation on p-type silicon.
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.
