New Data from Institute of Materials Research and Engineering Illuminate Findings in Organic Electronics (Temperature and light dependent diode current in high-efficiency solution-processed small-molecule solar cells)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Current study results on Organic Electronics have been published. According to news reporting originating in Singapore, Singapore, by VerticalNews journalists, research stated, "This paper reports on the detail analysis of the DC electrical and photoelectrical properties of the high-efficient (eta = 8.01% under standard 100 mW/cm(2) AM1.5 illumination) small molecule bulk heterojunction (SM BHJ) solar cells p-DTS(FBTTh2)(2)/PC70BM. In this SM BHJ solar cell, the dark diode current is determined by the multistep tunnel-recombination via interface states at low forward bias (V < 0.65 V) and the interface state assisted thermionic emission at high forward bias (V > 0.65 V)."

The news reporters obtained a quote from the research from the Institute of Materials Research and Engineering, "The effect of illumination on the diode current was also quantitatively investigated. It was observed a reduced Shockley-Read-Hall recombination via interface states at large forward bias (from the maximum power point to the open-circuit conditions)."

According to the news reporters, the research concluded: "The expression of the load I-V characteristic of the illuminated high-efficient SM BHJ solar cells was derived in the presence of the light dependent series and shunt resistance."
