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.
Cheaper renewable energy will leave new coal assets stranded
A new Ieefa report discusses the viability of under-construction coal-fired power plants and evaluates the associated stranded asset risk in building additional coal-fired capacity in India’s electricity system.
Hitachi ABB Power Grids to switch to 100% fossil-free electricity by year end
The company is working on electrified, reliable, and decarbonized operations and products to get closer toward a carbon-neutral future.
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.
Lead-free perovskite solar cell with potential efficiency of 27.4%
Scientists in India have simulated a perovskite cell based on methylammonium tin iodide which they claim may achieve a short circuit current density of 25.97 mA per square centimeter, an open-circuit voltage of 1.203 V, and a fill factor of 87.79%. The cell is composed of a fluorine-doped tin oxide (FTO) substrate, a titanium oxide layer, a methylammonium tin iodide perovskite film, a copper oxide hole transport layer (HTL), and a layer made of gold (Au).
Photovoltaic roof for highways
Researchers from Germany and Austria are testing how photovoltaic roofs may be deployed along highways. The first pilot project is planned to be implemented starting from the autumn.
Solar 101: How to evaluate solar contractors for rooftop projects
A well-designed rooftop solar system should last 20 or 30 years, or longer. This guide for choosing the right contractor should help ease your concerns.
