Germanium use reduced in GaAs solar cells by new two-step process
Researchers from Canada have unveiled a new germanium deposition process which is said to eliminate threading dislocations and be significantly cheaper than previous approaches. The scientists say their technique creates nanovoids on the surface of the germanium layer which can attract and annihilate undesirable dislocations.

New antenna for a better photon harvest
An Italian research team has developed a device that it says can easily be integrated into a PV cell, and can boost its efficiency by converting more light particles into a high energy state before they are absorbed by the cell. The scientists claim that their innovation could offer a green‐to‐blue photon upconversion yield as high as 15%.

New configuration gives perovskite cells 18% efficiency
Cesium lead black perovskites could be interesting for solar cell development if their crystals are observed in their less efficient but more stable beta phase. The efficiency shortfall can be solved by healing emerging cracks in the surface of the cell using a choline iodide solution, according to an international team of scientists.
