Solar Edition Instagram: According to Solardaily news, New research could lead to the design of new materials to help improve the performance of PSCs. PSCs are an emerging photovoltaic technology that has seen a remarkable rise in power conversion efficiency to above 20 percent.
The Perovskite material is responsible for absorbing light to create an electronic charge, and also for helping to extract the charge into an external circuit before it is lost to a process called ‘recombination’. The majority of detrimental recombination can occur in different locations within the solar cell. In some designs, it occurs predominantly within the perovskite, while in others it happens at the edges of the perovskite where it contacts the adjacent materials known as transport layers.
Researchers from the Universities of Portsmouth, Southampton and Bath have now developed a way to adjust the properties of the transport layers to encourage the ionic defects within the perovskite to move in such a way that they suppress recombination and lead to more efficient charge extraction – increasing the proportion of the light energy falling on the surface of the cell that can ultimately be used. ——————–***——————–
