How Solar 3.0 Technology Will Change Everything

Energy Efficiency No Comments »

As far as our limited capacities are concerned, the sun is essentially an infinite and renewable energy source. It’s like a giant fusion reactor millions of miles away, illuminating the earth with as much energy as the whole of human civilization uses in a year! So, why aren’t we making more use of such a boundless source to solve all our energy-related problems?
Well, we’re actually pretty close to getting there, and in today’s video, I will show you how!

Solar photovoltaic panels are currently limited to a maximum efficiency of about 30%, and in practice only actually achieve about 20% to 23% efficiency. Now a team in Cambridge has developed a film that can amplify the number of photons that the panel can use, with a potential increase in efficiency to as much as 35%. So how do they do that?

How Solar PV technology works

Energy Efficiency No Comments »

Solar photovoltaic (PV) technology converts sunlight directly into electricity. It works by harnessing the energy in sunlight to create an electrical current through a semiconductor material.

The basic components of a solar PV system are:

Solar panels (also called photovoltaic modules) made up of multiple solar cells connected in series.
An inverter that converts the direct current (DC) produced by the solar panels into alternating current (AC) that can be used in homes and businesses.
Electrical wiring that connects the solar panels to the inverter and the inverter to the electrical grid or battery storage system.

National Labs Improving Photovoltaic Technology

Energy Efficiency No Comments »

Solar photovoltaic technology continues to improve as scientists develop panels that are able to last even longer and convert increasing amounts of sunlight into electricity. SunShot Initiative projects at the National Renewable Energy Laboratory are working to develop solutions that will reduce the cost of solar panels by allowing them to transform more of the sun’s rays into electricity for decades to come. Learn more about SunShot’s 2030 goals at energy.gov/sunshot2030.

The Future of U.S. Solar Photovoltaic Technology – Q&A – Tonio Buonassisi

Energy Efficiency No Comments »

The solar photovoltaic (PV) industry continues to grow, despite intense international competition and recent margin compression.

Can innovation in technology and manufacturing allow American companies to compete and ultimately thrive in this huge but challenging market?

Professor Buonassisi will address these questions as he explores the outlook for American PV cell and module suppliers. He will begin by using an industry-validated bottoms-up cost model to compare the cost-reduction potentials of various innovative PV technologies, and how their successful development could influence manufacturing location decisions. He will also describe recent progress toward these innovative technologies, highlighting the new computational and experimental tools that have accelerated the cycle of discovery and product development — providing “sneak peeks” at the technologies that may grace rooftops in years to come. He will conclude by showcasing recent success stories of U.S. innovation.

Join us as Professor Buonassisi explains how technology innovation will open up pathways for success in the U.S. solar PV industry.

Tonio Buonassisi, MIT Associate Professor of Mechanical Engineering, heads an interdisciplinary research laboratory focused on photovoltaics (PV). He completed his Ph.D. in Applied Science & Technology at UC Berkeley, with additional research at the Fraunhofer Institute for Solar Energy Systems and the Max-Planck-Institute for Microstructure Physics. He is author of over a hundred journal papers, and co-developer of a dedicated course on photovoltaics.

Prof. Buonassisi invents, develops, and applies defect-engineering techniques over the entire solar cell process, from crystal growth to modules, improving the cost effectiveness of commercial and next-generation solar cells. Several of his PV innovations have been implemented in industry, including key contributions leading to the founding of solar start-ups and a research institute.

Bioenergy Technology | Wagner Alegretti | TEDxPassoFundo

Renewable Energy No Comments »

Could a “new” form of energy lead to a new type of technology? Wagner Alegretti, an engineer and consciousness researcher, shares his research on detection of bioenergy (biofield) using functional magnetic resonance imaging (fMRI), as well as other methods, and discusses how this knowledge could be the basis for the development of a groundbreaking technology. He invites other researchers to replicate his experiments for more robust evidences.

Wagner has worked in the fields of electricity generation, software development, and medical electronic equipment. He has travelled throughout the world participating in a number ofcongresses and events. Wagner is a charter member of the Institute of Applied Consciousness Technologies and of the International Academy of Consciousness, a non-profit research and education organization of which he was president for 14 years.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

In this video, we are going to look at Solar Photovoltaic Thermal Hybrid collector or in short PVT. Its a combination of solar thermal collectors and PV cell.
The removal of heat from PV cells is also improved and the overall output increases to 85%. The added output is in the form of heat.

Given that over 50% of the energy we consume is in the form of heat, this is a valuable device.
