Printed solar cells to produce green electricity

Solar power has declined dramatically its cost over the past decades. We could say that was a decrease from $40 per watt in 1978 to $0.42 per watt in 2015. In the next three years the cost of production for conventional crystalline silicon solar panel could attend more than 30 percent less. The important players […]

Evaporation water to drive for green electricity

Scientist from Columbia University has developed two engines that can generate green electricity from evaporation water. This clean renewable energy source could help to power robots, sensors or any other small devices. It is already known from biology that redwood trees rely on evaporation to pull water from the ground to their crowns, into a […]

Swiss solar powered aircraft to energy efficiency

The Swiss team composed by: Andre Borschberg and Bertrand Piccard were stopped by the weather in their attempt to circumnavigate the Earth in an experimental solar powered aircraft called Solar Impulse 2. The weather conditions worsened soon after embarking and the solar powered aircraft was forced to land on June 1st in Nagoya, Japan after […]

Spherical solar energy collector made by Rawlemon

According to its vision, the German architect Andre Broessel said that the future will be not only green, but transparent. He and his Rawlemon company have a solution that can “squeeze more juice out of the sun”. He projected a spherical solar energy collector, a prototype called beta.ray. Its technology combines spherical geometry principles with […]

MIT energy initiative for an efficient solar cell in the future

Solar energy can fulfil us, as humanity, our long term energy needs. This could offer the cutting of greenhouse gas emissions by developing lower cost technologies and more effective deployment policy as is written in an MIT Energy Initiative (MITEI) study called The Future of Solar Energy. As Mr. Robert Armstrong –The Director of MITEI […]

Vortex Bladeless – future wind turbines for green electricity

Innovation is the core key of any concepts improvement even when is about green electricity. When talking about wind turbines the surprise has already appeared. A new kind of approaching in using the wind energy to produce green electricity was developed by a Spanish team. They choose to eliminate blades but being more inventive. Their […]

CZTS the next level for IBM photovoltaic scientists

According to IBM photovoltaic scientists, copper, zinc, tin and selenium – CZTS, will yield efficient thin-film solar cells made from abundant materials. Photovoltaic scientists from IBM Teodor Todorov and David Mitzi detailed the findings of a paper that describes the highest efficiency for solar cells made from CZTS. The technical paper published in Advanced Energy […]
