Two years of perovskite progress

Scientists in China examined some of the key achievements in the development of perovskite solar cells in 2020 and 2021. The group finds that translating laboratory achievements onto larger, manufacturable devices, is the biggest challenge, and sees continuing collaboration between the industry and academic researchers as the key to overcoming this challenge.

Walking on sunshine

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.

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.
