A merger led by ICIQ’s Palomares group will help get better analysis about effect of changing materials in perovskite solar cells. The collaboration deepens the performance analysis in this case. Energy and Environmental Science, a peer-reviewed journal, published the report. The report provides the structure of elements of solar cells, fueling their business appeal. Perovskite is a mineral consisting mainly of calcium titanate. It is yellow, black, and brown in color.
The merger among researchers from the Physical Chemistry of Surfaces and Interfaces group at the Institut de Ciència de Materials de Barcelona (ICMAB-CSIC) and ICIQ’s Palomares, and IMDEA Nanocienca, draws attention towards the factors responsible for differences in performance of perovskite solar cell. It compared four various Hole Transport Materials Hole Transport Materials (HTMs) available around physical and chemical properties.
Small Changes Could Make Huge Differences
Perovskite solar cells is one of the most rapidly growing technologies till date. The perovskite-based solar cells have gained extended efficiency since they were first introduced, back in 2009. This is more than 22% over ideal solar irradiation, and is possible at extremely low price. Even though maximum perovskite elements are optimized, there is still a scope for advancement; particularly, with reference to HTMs.
Perovskite solar cells are nearing the stability required for being reliable and to be used as commercial products. Usage of material is the key issue, especially, spiro-OMeTAD. It is the most used HTM among all, which is prone to more degradation. As a result, the study has focused on finding the option for it.
Researchers were trying to design new molecules to replace spiro-OMeTAD, since years. They were discovering molecules that had similar optical and electrical features as spiro-OMeTAD, and were expecting similar outcomes. Nevertheless, while testing new HTMs, the cells reacted badly. So, they made effort to analyze the reason behind this.
