The aim of this work is to study the photovoltaic performance of a solar cell based on GaSe
materials using SCAPS-1D simulator. The novelty of this work consists in the use of GaSe …

Thin film solar cells based in Cu (In, Ga) Se2 (CIGS) are among the most efficient
polycrystalline solar cells, surpassing CdTe and even polycrystalline silicon solar cells. For …

In the past years, the strategies used to break the Cu (In, Ga) Se 2 (CIGS) light to power
conversion efficiency world record value were based on improvements of the absorber …

For applications to semi‐transparent and/or bifacial solar cells in building‐integrated
photovoltaics and building‐applied photovoltaics, studies are underway to reduce the …

Abstract In recent years, Cu 2 ZnSnS 4 (CZTS) semiconductor materials have received
intensive attention in the field of thin-film solar cells owing to its non-toxic and low-cost …

We improved the efficiency of ultra‐thin (0.49‐μm‐thick) Cu (In, Ga) Se2 solar cells to
15.2%(officially measured). To achieve these results, we modified growth conditions from …

We present a simulation strategy using ATLAS-2D to optimize the back-contact hole grid (ie,
size and pitch of openings) of the Al 2 O 3-rear-passivation layer in ultrathin Cu (In, Ga) Se 2 …

Abstract Cu (In, Ga) Se2‐based (CIGS) solar cells with ultrathin (≤ 500 nm) absorber layers
suffer from the low reflectivity of conventional Mo back contacts. Here, we design and …

Abstract Reducing the Cu (In x Ga 1− x) Se 2 (CIGS) thickness is an effective way to reduce
the material use and increase manufacturing throughput. However, it is still a challenge to …

Transparent photovoltaic (TPV) devices using very thin absorbers, which are sandwiched by
transparent conducting front and rear contacts, provide efficient solar energy yields and …
