Harnessing energy from glass walls: Semi-transparent perovskite solar cells have been developed that could be great candidates for solar windows

Korea Advanced Institute of Science and Technology, Science Daily, 29 May 2017  A Korean research team has developed semi-transparent perovskite solar cells that could be great candidates for solar windows. Scientists are exploring ways to develop transparent or semi-transparent solar cells as a substitute for glass walls in modern buildings with the aim of harnessing solar energy. But this has …

Off-grid renewables may be lowest-cost option for connecting more than one-fifth of Africans needing electricity access, says Dutch report

In many parts of sub-Saharan Africa, adding distributed renewable power may be more cost-effective than extending the grid to those without access to electricity, says a Dutch government report. The need is vast, with more than 600 million people on the continent living without electricity. Climate Home reports on the study here. And here’s a story we ran earlier this …

Renewable energy is ‘unstoppable’, declares Financial Times:  ‘Fossil fuels have lost. The rest of the world just doesn’t know it yet.’

At least 14 battery gigafactories are being built or planned, nine in China.  Joe Romm shares some highlights from a new, must-read, 4000-word article in the Financial Times, “The Big Green Bang: how renewable energy became unstoppable.” Traditional energy companies and mainstream financial publications are finally waking up to the new reality: The shift to renewable energy, electric cars, and …

Just 10 of these printers could print enough flexible solar PV to power 1000 homes per day, current cost is $10/square meter

By Steve Hanley, Clean Technica, 17 May 2017 Researchers At Australia’s University Of Newcastle Testing Printed Solar Panels A team of researchers headed by Professor Paul Dastoor at the University of Newcastle in Australia has begun testing printed solar panels. The experimental panels are made by printing a special electronic ink onto clear laminated sheets as thin as a single piece …

Utilities and solar finally finding ways to work together, especially as utilities will be ultimate owners of many solar projects

 By Travis Hoium, Motley Fool Investing, 8 May 2017 Utilities and solar companies have long had a strange relationship. On one hand, they compete over compensation for customers wanting to put solar on their roofs, and on the other, they partner to provide solar energy from utility-scale projects to thousands of customers. But the two sides have been figuring out …

Tesla solar roof generates more than its cost in electricity and is guaranteed to outlive your home (good for hail prone areas)

From Bloomberg, May 10, 2017 Tesla Inc. has begun taking $1,000 deposits for its remarkable solar roof tiles—to be delivered this summer at a price point that could expand the U.S. solar market. Tesla will begin with production of two of the four styles it unveiled in October: a smooth glass and a textured glass tile. 1 Roofing a 2,000 square-foot home in New York …

India is advancing dye-sensitized solar cells with local fruits

Wikipedia: dye-sensitized solar cells:  A dye-sensitized solar cell (DSSC, DSC, DYSC[1] or Grätzel cell) is a low-cost solar cell belonging to the group of thin film solar cells.[2] It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. The modern version of a dye solar cell, also known as the Grätzel cell, was …

“This is a different world from three years ago” — renewables are no longer “alternative energy”

Joe Romm, Climate Progress, April 30, 2017 Renewables and efficiency have already won the battle for the future of electricity according to Bloomberg New Energy Finance (BNEF).  In his keynote talk at the end of April 2017, BNEF founder and chair Michael Liebreich explained that if you blinked, you missed the clean energy revolution: “This is a different world from three …

“Solar Ink” and new fast production ways to manufacture perskovite cells

By Tina Casey in Clean Technica, 17 April 2017   Thin Film Solar Cells Are Coming On Strong Thin film solar cells are generally not as efficient as conventional silicon solar cells, but they do possess several key advantages that can counterbalance that shortcoming.  Thin film solar cells can be manufactured at high speed and at high volume, using roll-to-roll …
