A new solar cell has broken all previous solar efficiency records by achieving 44.7% efficiency, meaning it converts almost half of all the light hitting it into energy. Go to Source Tags: Fraunhofer Society, Concentrated photovoltaics, Solar, Solar cell, Technology ...

Wenjing Qin, Xinrui Xu, Dongyue Liu, Chunyu Ma, Liying Yang et al.<br/> ZnO is a promising material used as the electron transport layer in the inverted organic solar cells (IOSCs). However, the electrical or photoelectric properties of ZnO nanoparticles are governed by the surface states of the nanoparticles. Here, we demonstrate that the large number of hydroxyl...

Team ASUNM, a collaborative effort between Arizona State University and the University of New Mexico, has come together to address the inefficiencies of urban sprawl and to create a model for sustainable desert living that has been dubbed SHADE, or Solar Home Adapting for Desert Equilibrium, an entry in the Solar Decathlon 2013 competition that takes place October 3–13,...

A brand-new Mexican tech startup is making its products affordable using a centuries-old financing trick that lets startups and their customers shift their risk toward third-party investors. Even a $15 product is too expensive for many of the world’s poorest customers. Solar companies have made headlines in recent years with myriad solutions to making their products...

Guest post by Paul Polak, author, “Out of Poverty” and founder of International Development Enterprises What if we could harness the limitless power of the sun to carry water to the crops of millions of small poor farmers around the world? If I want to water my petunias, I turn on the tap outside my house, hold my thumb over the end of a battered green hose and...

An estimated 780 million people around the world lack access to clean drinking water and 1.3 billion people are still without access to electricity. Twenty-year-old...

High-pressure chemistry techniques have been used to make a fibre out of crystalline silicon semiconductor materials that can function as a solar cell. Go...
