cheap transparent solar cells The record has been broken

For many of us, photovoltaics are essentially classic PV units installed on suburban rooftops. However, electricity can be generated from the sun in different ways. Scientists have now broken the performance record for sensitive dye-based solar cells.

Translucent photovoltaic cells move scientists. There are other options on the market that can be widely used. The possibility of using this type of technology, for example in window panels, will allow the widespread use of photovoltaic cells, for example in office buildings.

Dye-sensitive cells (DSC) are one of the possibilities for implementing transparent photovoltaic installations. Scientists from the Federal Polytechnic University of Lausanne have taken another step in developing this technology. Thanks to their work, these inexpensive transparent photovoltaic cells have achieved higher efficiency, thanks to which the possibility of their widespread use is becoming more and more.

How We read On techspot.com, DSC cells were invented in 1988 thanks to the collaboration of Brian O’Regan and Michael Gratzel. This concept is based on a semiconductor formed between a photosensitive anode and an electrolyte. Such a photovoltaic system converts solar radiation into electricity.

This solution is characterized by low production costs, but is ineffective. They are often used in building facades, but the low efficiency means that the energy yield is not very high.

However, Swiss researchers found a way to break the record for the efficiency of a single DSC, setting its value at 15.2%, while maintaining long-term operational stability of more than 500 hours. In the case of an active area of ​​2.8 square centimeters, the energy conversion efficiency reached a maximum of 30.2 percent.

In a study published in Nature, scientists describe the process of achieving record-breaking efficiency for a cell. They achieved the present results by optimizing the packing of photosensitizer particles with a single layer of hydroxamic acid.
