Researchers at NTU Singapore Recorded the Highest Power Conversion Efficiency
A team of researchers at the Nanyang Technological University, Singapore (NTU Singapore) has created a perovskite solar mini module that has recorded the highest power conversion efficiency of any perovskite-based device larger than 10 cm2.
Perovskites are new materials that have emerged as promising alternatives to silicon in solar cell applications. The material offers power conversion efficiencies similar to silicon solar cells but can also be used to create light-weight flexible and semi-transparent cells ideal for applications in buildings and a variety of urban spaces. Perovskite technologies are progressing rapidly towards industrialisation, with stability and scalability to larger sizes seen by researchers as the last hurdles to overcome.
Now NTU researchers report that they have adopted a common industrial coating technique called ‘thermal co-evaporation’ and found that it can fabricate solar cell modules of 21 cm2 size with record power conversion efficiencies of 18.1 per cent. These are the highest recorded values reported for scalable perovskite solar cells.
Thermal evaporation is an established coating technique currently used to produce electronics including Organic Light Emitting Diode (OLED) TVs.
