Scientists from the Polytechnic University of Hong Kong have been researching for two years – the result is novel organic solar cells (originally: Organic Solar Cells, in short: OSCs). One also speaks of polymer solar cells.
The special: The researchers have developed a new technique; Thanks to this, OSCs achieve an efficiency of 19.3 percent. Until now, OSCs have been considered too inefficient and expensive for commercial use (Independent and Techxplore have reported on Nature Communications).
The scientists are currently hoping to achieve an efficiency of over 20 percent. In any case, the research group from the University of Hong Kong is confident of breaking the 20 percent mark.
Li Gang of Hong Kong Polytechnic University says:
“The potential applications for wearable electronics and photovoltaics are likely to be enormous. […] I have been driving the development of OSCs for over two years. The current research results encourage me a lot. The efficiency of the OSCs has been significantly improved.”
What is special about OSCs is: They are lighter and more flexible than conventional silicon-based solar cells. Organic solar cells consist of a thin layer of semiconductor materials. In addition, OSCs are up to 1,000 times thinner than ordinary silicon solar cells and are also said to be more environmentally friendly (Independent has reported).
According to the scientists, potential use cases for OSCs can be found in: Building components (including windows, for example), portable electronic devices or photovoltaic systems.
By the way: So-called balcony power plants are becoming increasingly popular – as our article by Dennis Ziesecke, which is well worth reading, proves. If you want to know what a balcony power plant is, what solar cells have to do with it, and how (or whether) Dennis was able to save electricity after 8 months of balcony power plant power, you can find out in his article.
What do you think of the new solar panels from China? Is this a development that you are watching with excitement or is your tongue tying itself up at the word “photovoltaic system”? So please let us know in the comments whether you even own a balcony power plant yourself or want to get one.
