Unveiling a Near‐Total Rear Passivation for High Performance of Ultra‐Thin ACIGS

ABSTRACT Thin‐film Cu(In,Ga)Se 2 solar cells are a key photovoltaic technology for addressing global energy and environmental challenges. Reducing absorber thickness lowers manufacturing cost and critical raw material consumption but introduces optical and electrical losses due t...

Nanoscale Rear‐Interface Architecture Enables 36.2 mA cm −2 Photocurrent in Ultrathin and Bifacial ACIGS Solar Cells Through Light Management

ABSTRACT Reducing the absorber thickness in thin‐film photovoltaics has a direct impact on low raw material consumption and high manufacturing throughput. However, it leads to low optical performance due to incomplete light absorption. In (Ag,Cu)(In,Ga)Se 2 (ACIGS)‐based technolo...
