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.
ReNew Power joins Stanford initiative on battery storage
Stanford University’s StorageX Initiative brings together academia and industry to tackle the dominant challenges in energy storage. ReNew’s collaboration with StorageX will initially focus on large-scale battery performance in India.
Smart sticker for smart solar modules
The sticker is based on a blockchain technology developed by German start-up Authentic Network. Meyer Burger uses the application for the photovoltaic modules it produces in its new factory that opened in Freiberg at the end of May.
A repair tape for cracked backsheets
Backsheet failures have plagued the industry, causing hefty financial burdens to many asset owners. DuPont has launched a product it says allows for easy repair of modules.
Longi achieves 25.21% efficiency for TOPCon solar cell
The Chinese module manufacturer said the result was confirmed by the Institute for Solar Energy Research in Hamelin, Germany.
Nano-micro-scale cooler for solar modules
The proposed technique is based on radiative cooling and consists of a glass coating made with a two-dimensional subwavelength nanostructured grating, which is imprinted in soda-lime glass and has enhanced mid-infrared emissivity, and a micro-structured grating. The temperature decrease provided by the nano-micro-grating coating was found to be approximately up to 5.8 degrees Celsius.
India, Russia to fund joint R&D in clean energy
India’s Department of Science & Technology and the Russian Science Foundation (RSF) have launched a collaborative funding program for Indian and Russian researchers to jointly research clean energy, new materials, and smart transport.
Adhesive mounting system for any kind of solar modules
The system, developed by Spanish specialist Alusín Solar, is being tested by Endesa in a 9.8 MW project for self-consumption. The mounting structure is made with aluminum bars that, instead of being fixed to the roof with screws, are attached through a double-sided adhesive.
