Photovoltaics of the future: what’s new and how it will change

The world record for the efficiency of solar cells for photovoltaic systems was broken, thanks to a research group led by the Wuppertal Institute in Germany, in which the threshold of 24% was reached, setting a new record, which was previously at 20%. This innovation can bring many benefits to the future of renewable energy, especially solar energy, let’s discover together the record and advantages for the future.

The difference of 4 percentage points bodes well for the research group in Germany . The Solar Technologies involving the use of silicon The ideal material to ensure less space and perfect functionality in terms of efficiency, in the relationship between Solar energy is fed and electric power is generated. how many Watts of solar energy The accident is producing Electric Watts?

The work was funded by the programme Deutsche Forschungsgemeinschaft (DFG) on a perovskite semiconductor (SPP 2196) and published in temper nature.

How has painting technology changed?

One can hope to reduce costs associated with the use of these technologies, but this means compliance with environmental standards of production that can be reduced.

The way forward to achieve improvement in terms of Efficiency and cost reduction about a change in technology, which was made by researchers at Wuppertal Institutewho succeeded in inserting a file Organic materials As an exchange substance in the plant.

Thomas RiddellThose who led the research intervened as follows:

“In our group, we also consider organics Semiconductors and Perovskite Semiconductors instead of silicon. Both technologies have shown amazing development in recent years and their efficiency is now comparable to silicon. At the same time, these technologies greatly require Less materials and energy in productionmaking it more sustainable with short energy payback times.”

However, the group did more built-in technologies. So it continues Kay Brinkman first author of the work:

“Everything becomes more wonderful if you collect organic solar cells And perovskite so called Tandem cell. It must be remembered that sunlight is a mixture of different components. basic constraint for Solar cells It is because of the part of the light that the cell does not absorb or convert into electricity. Tandem cells, where two different solar cells operate with two different regions of the spectrum, provide a way around this problem.”

An essential part of the success of new technology is “bonding“which provides connection to both cells electrically and optically. In essence, by working together, the Two cells absorb more lightNeither Convert more and do it Increase overall efficiency the system.

To ensure that process intercellular communication and reduce energy lossesthe researchers used very thin layers of indium oxide 1.5 nanometers thick and covered with atomic layers.

Lasts Riddle:

“An important part of the success is the network of partners, notably the Universities of Cologne, Potsdam and Tübingen, the Helmholtz Center in Berlin and the Max Planck Institute for Isenfurschung in Düsseldorf, whose extensive experience helped clear critical issues on the path that eventually led us to Tandem solar cells perovskite / organic With’24% efficiencyA new world record for this type of tandem.

The team has no plans to stop now that the results are approved and are just waiting to be presented in the lab to ensure.”New technology manufacturing.

Technique

future project

“At the time when we started this project i perovskite/organic tandem It was only 20% effective. We are now 24 and simulations show that our concept should allow us to achieve efficiencies even further 30%”

Achieving this goal is not fancy, in fact Solar cells used in Void On the drone Mars’ creativity However, unfortunately it is still not applicable on Earth due to the high costs that would make Unsustainable technology.

Concludes Riddle:

We hope that our work will contribute to a scenario where Solar cells Similar in terms of high efficiencies but at a fraction of the costs reduced to be available for land use”

good hope for renewable In particular photovoltaic cellswhich thanks to these innovations will be able to guarantee a Good alternative to fossil fuels And why not, it can help us reach energy conversion For the future.
