Thermoelectric Material Inverse Perovskites Generate Power
January 17, 2024 | Leave a Comment
Tokyo Institute of Technology scientists report in a new study environmentally benign inverse-perovskites with high energy conversion efficiency have potential for practical application as thermoelectric materials (TEMs). The recent study published in Advanced Science, the researchers presented “inverse”-perovskite-based high ZT TEMs with the chemical formula Ba3BO, where B refers to silicon (Si) and germanium (Ge).

Perovskite Solar Cell Speed Tested
September 27, 2017 | 3 Comments
St John’s College, University of Cambridge, researchers have quantified the astonishingly high speeds at which future perovskite solar cells would have to operate in order to stretch what are presently seen as natural limits on their energy conversion efficiency. The study investigating perovskite photovoltaic suggests that these could achieve unprecedented levels of super-efficiency. But to […]

Solar Cells For Up North Get a Huge Improvement
May 27, 2015 | Leave a Comment
Aalto University researchers have obtained the record-breaking efficiency of 22.1 percent efficiency on nanostructured black silicon solar cells. This critical almost 4 percent absolute increase to their previous record was achieved by applying a thin passivating film on the nanostructures and by integrating all metal contacts on the back side of the cell. Most folks […]

New Record Set For Flexible Solar Cells
May 24, 2011 | 2 Comments
Swiss Federal Laboratories for Materials Science and Technology scientists at Empa have further boosted the energy conversion efficiency of flexible photovoltaic solar cells made of copper indium gallium (di)selenide (also known as CIGS) to a new world record of 18.7 percent. The same team achieved the previous record of 17.6 percent in June 2010 making […]
