Harvesting solar energy using organic solar cells has been considered a viable alternative energy option mainly due to their light weight, low production costs and mechanical flexibility. The use of ...

When sunlight shining on a solar cell reaches the photosensitive perovskite layer, typically an alkyl ammonium trihalide, the light excites the material, forming energetic couples consisting of ...

The Chinese Academy of Sciences has developed a black perovskite solar cell that reportedly achieved the the highest efficiency ever reported for PV devices built with this perovskite material and a ...

Researchers in China have built a hole transport layer with a mixed binary configuration integrating the polymer Regioregular poly(3-hexylthiophene) (P3HT) and Spiro-OMeTAD. They used it to build a ...
