Abstract Bifacial Cu (In, Ga) Se2 (CIGS) solar cells are attractive for a range of applications,
but their low power conversion efficiency is a limitation. To improve their efficiency, the …

The rapidly develo** perovskite solar cells (PSCs) provide a new and promising choice of
thin film solar cells due to their attractive attributes. Among the commercialized thin film solar …

Although an ideal bandgap matching with 0.96 eV and 1.62 eV for a double-junction tandem
is hard to realize practically, among all mature photovoltaic systems, Cu (In, Ga) Se2 …

In this work, different copper-based thin-film materials as a hole transport layer (HTL) are
introduced in Cu (In, Ga) Se 2 (CIGS) solar cells to limit the recombination rate at the back …

Point defects directly impact solar cell device performance by limiting the carrier lifetime. In
this work, density functional theory calculations are first used to determine the formation …

To achieve a high fill factor, a small diode factor close to 1 is essential. The optical diode
factor determined by photoluminescence is the diode factor from the neutral zone of the …

Abstract Ultra‐thin Cu (In, Ga) Se2 (CIGSe) solar cells on transparent conductive oxide back
contact reduce the material consumption of rare indium and gallium and simultaneously …

The vapor-transport deposition of SnS and SnSe can help achieve low-cost and scalable
photovoltaic devices. However, the performance of SnS-and SnSe-based solar cells is …

The copper indium gallium selenium (CIGS) thin film is widely acknowledged as the most
promising material for photovoltaic applications. Mainly due to appealing chemical and …

Alkali treatments are crucial for low bandgap (Ag, Cu) InSe2 (ACIS) and Cu (In, Ga) Se2‐
based solar cell performance. Traditionally, Ag‐alloying of CIS (ACIS) is grown on soda …
