In 1991, scientists Brian O'Regan and Michael Grätzel at EPFL published a seminal paper describing a new type of solar cell: the dye-sensitized solar cell (DSSC), also known as "Grätzel cell".
A new, simpler solution process for fabricating stable perovskite solar cells overcomes the key bottleneck to large-scale production and commercialization of this promising renewable-energy technology, which has remained tantalizingly out of reach for more than a decade.
Schlumberger New Energy announced today the development of a lithium extraction pilot plant through its new venture, NeoLith Energy. The deployment of the pilot plant will be in Clayton Valley, Nevada, USA.
Silicon solar cells are now so cheap and efficient that they can generate electricity at prices of less than 2 cent/kWh. The most efficient silicon solar cells today are made with less than 10 nanometres thin selective amorphous silicon (a-Si:H) contact layers, which are responsible for separating the light-generated charges .
As researchers push the boundaries of battery design, seeking to pack ever greater amounts of power and energy into a given amount of space or weight, one of the more promising technologies being studied is lithium-ion batteries that use a solid electrolyte material between the two electrodes, rather than the typical liquid.
Solar energy is considered one of the most significant eco-friendly and fossil-free sustainable sources of electricity. The existing silicon-based solar cells use only around 33% of the energy in sunlight and transform it into electricity.
A new fabrication technique could allow solid-state automotive lithium-ion batteries to adopt nonflammable ceramic electrolytes using the same production processes as in batteries made with conventional liquid electrolytes.
Individuals who have owned a smartphone for more than a year would probably know that the integrated lithium (Li)-ion battery does not retain as much charge as it did when the phone was new.
Around the world there are currently more than 18 billion internet-connected mobile devices. In the next 10 years, anticipated growth in the Internet of Things (IoT) and in machine-type communication in general, will lead to a world of hundreds of billions of data-connected objects. Such growth poses two very challenging problems:
Nanoengineers from the University of California, San Diego (UC San Diego) have gained a new fundamental insight for designing lithium metal batteries that work well at very low temperatures; specifically, the weaker the electrolyte binds to lithium ions, the better.
