Researchers in China developed a monolithic perovskite-silicon tandem solar cell using a steric-complementary interface design, achieving a certified efficiency of 32.12% and enhanced long-term ...

A research team in Spain has built what it claims to be the world's most efficient perovskite solar cell using MXenes or any other type of 2D-materials. The device relies on a Mxene interlayer that ...

Earlier in 2025, Chinese solar manufacturer Longi announced it had built the world's most efficient solar cell. The hybrid interdigitated back-contact (HIBC) cell achieved 27.81% efficiency, which was ...

A "charged" metal hydride is still at least 90% metal and, as of today, 7% or so hydrogen. Energy density is not as good as a lithium-ion battery, but metal hydrides are safe, easy to store and unlike ...
