Composition pinning growth for efficient and stable all‐inorganic Pb‐Sn perovskite solar cells

InfoMat, EarlyView.
All‐inorganic Pb‐Sn perovskite solar cells are promising for low‐bandgap photovoltaics, but uneven Pb/Sn composition during film growth can create defects and reduce performance. In this study, composition pinning growth was used to hold the Pb/Sn ratio steady during CsPb0.5Sn0.5I3 crystallization, producing more uniform films and higher‐performing ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Near 13% Efficient Semitransparent Cu(In,Ga)S2 Solar Cells With Band Gap of 1.6 eV on Transparent Back Contact

Progress in Photovoltaics: Research and Applications, EarlyView.
This work demonstrates progress in the development of wide‐bandgap CIGS solar cells featuring a transparent back contact, for the application of top cell in tandem devices. A semitransparent device with a bandgap of 1.6 eV achieved a power conversion efficiency of nearly 13% on an ITO back contact.

Optimizing Na and Rb Incorporation Along With Bandgap Grading for High Efficiency Ultra‐Thin CIGSe Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
In this work, Na and Rb are incorporated into ultra‐thin Cu(In,Ga)Se2 (< 500 nm). By systematically varying the Rb content and combining predeposited Na with postdeposited Rb, we identify the optimal configuration, achieving solar cell efficiencies of 11.72% on Mo and 10.48% on ITO. Through electrical and compositional measurements, a mechanistic model
