Laser Etch a Perfect Radiant Energy Absorber

March 12, 2020 | Leave a Comment

University of Rochester researchers have demonstrated how laser etching of metallic surfaces creates the ”perfect solar energy absorber”. This not only enhances energy absorption from sunlight, but also reduces heat dissipation at other wavelengths. The researchers also demonstrated solar energy harnessing with a thermal electric generator. The University of Rochester research lab that recently used […]

The thermocell contained a material that exhibited a phase transition from one arrangement of atoms to another when heated to 50° C (122° F).. The phase transition caused the output voltage of the thermocell to […]

A Photovoltaic Cell That Works at Night

February 5, 2020 | Leave a Comment

University of California Davis researchers are asking, “What if solar cells worked at night?” They are not joking. In fact, their specially designed photovoltaic cell could generate up to 50 watts of power per square meter under ideal conditions at night, about a quarter of what a conventional solar panel can generate in daytime, according […]

New World Record Set For Making Electricity From Heat

December 17, 2019 | 1 Comment

Vienna University of Technology (TU Wien,Vienna) scientists have now developed a completely new material with a ZT value of 5 to 6. It is so effective that it could be used to provide energy for sensors or even small computer processors. Thermoelectric materials convert heat into electrical energy. The amount of energy that can be […]
