Chinese scientists have developed a PV floor tile they say is suitable for pavements and cycling tracks. The devices were tested on a ‘green deck’ in Hong Kong. The developers say the tiles have demonstrated satisfactory solar energy conversion, anti-slip performance, heat-resistance and strength.
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.
