Flexible perovskite solar cell with 21.0% efficiency, high durability
International researchers have placed a low-dimensional metal-halide perovskite capping layer on top of a metal-halide perovskite film to provide hermetically sealed encapsulation and enhanced photocarrier properties. The cell has a short-circuit current density of 23.5 mA.cm2, an open-circuit voltage of 1.15 V, and a fill factor of 0.779.
New process to recycle silicon, silver and glass from end-of-life PV panels
A €4.8 million EU-funded research project is aiming to develop a process that allows recovering all components of a photovoltaic module.
The long read: Dial manganese for battery stability
Often sidelined by nickel and cobalt when it comes to batteries, the metal manganese is finding proponents in science and industry – in particular, by those attempting to avoid supply and cost issues. Ian Morse reports on the role of manganese in battery cell production.
Simplifying solar cell deposition
Scientists in Germany have developed a new process for deposition of silicon dioxide layers during cell production. Without the need for high pressure, flammable gases, or vacuum conditions, the process could lead to cost reductions for cell manufacturers, provided it can be developed and applied in a large-scale production setting.
