“…As a first step towards efficient contact formation, a low contact resistivity must be established for effective electron extraction from the c-Si to the Al. [4,45] To investigate the contact resistivity of the c-Si/a-Si:H(i)/SAM/Al contact, Cox and Strack method (CSM) [46,47] test structures were fabricated as illustrated in Figure 1a. In this measurement, the rear contact was formed by thermally evaporated silver (Ag) on highly doped n-type poly-Si.…”

Effective charge carrier‐selective contacts are a crucial component of high‐performance crystalline silicon (c‐Si) solar cells. Organic materials deposited via self‐assembly on the c‐Si surface are promising candidates for simplified, scalable, and cost‐effective processing of charge extraction layers. This study investigates the application of nPACz self‐assembled monolayers (SAMs), based on carbazole and phosphonic acid groups, where n (= 2, 4, or 6) is the aliphatic chain length, to facilitate electron extraction in c‐Si solar cells by tuning the work function of aluminum (Al) at the rear contact. So far, these SAM molecules are mainly applied as the hole‐selective layer in state‐of‐the‐art perovskite and organic solar cells, via anchoring on a metal oxide electrode. Here, by inserting 2PACz between amorphous silicon passivated c‐Si and Al, an electron‐selective contact with a contact resistivity of 65 mΩ cm2 is achieved and a power conversion efficiency of 21.4% with an open‐circuit voltage of 725 mV and a fill factor of 79.2% is demonstrated. Although the 2PACz displays some instability in this study, its initial performance is comparable to those achieved with conventionally used n‐type amorphous silicon. This study highlights the potential of solution‐processable organic SAMs in forming carrier‐selective contacts for c‐Si heterojunction solar cells.

“…10 Dark current-voltage measurements were conducted at room temperature using a Keithley 2425 source meter. The contact resistivity was calculated using the Cox-Strack method, 57 utilizing n-type silicon substrates with a resistivity of ∼1 U cm and a rear phosphorus diffusion. To determine lm thicknesses and optical constants (refractive index n and absorption index k), variable-angle spectroscopic ellipsometry measurements (J.A.…”
