Recently one group of scientists led by the Fraunhofer Institute for Solar Energy Systems ISEtogether with the Oxford PV company has made significant progress in the field of photovoltaic technology, especially in solar panelsand they have successfully created a large-scale tandem photovoltaic module.
Innovative fusion of perovskite and silicon solar cells, achieving an unprecedented return of 25%. This device has an area of 1.68 m2, its main feature being the ability to produce 421 W, consolidating itself as the most effective perovskite-silicon tandem solar module in the industrial field worldwide with an efficiency of 43%. statistics In contrast to the capacity limit, which is below 30% for conventional silicon solar cells, this one stands out in particular from the Franunhofer ISE team.
The aforementioned team has not only highlighted its viability, but also the possibility of producing a tandem PV module at a 25% level, using technology strategically aligned with mass production standards. This success indicates a very favorable horizon for technological science within the panorama of the photovoltaic industry.
How does a photovoltaic cell work?
A photovoltaic cell acts as an amazing magical workshop that helps solar panels do just that converts sunlight into electricity. It uses some specific materials that cause the movement of electrons when touched by sunlight, generating energy that we can use to power various applications. Imagine if a fragment of the sun works only for your own service!
What is perovskite and what benefits do they offer for solar panels?
Within the fascinating universe of materials science, a special component stands out, called perovskite. It works analogously to building blocks, but instead of building buildings, its function is to capture sunlight and convert it into electricity, returning to this extremely attractive material as it comes. to use it in solar panels and other environmentally friendly devices.
Perovskite is a mineral with a unique structure that repeats itself like a design; it is made up of different chemical components. The interesting thing about this material lies in its possibility to replace some of these components with othersthus increasing its effectiveness in capturing sunlight or its performance in different situations.
Currently, there is a long list of scientists raving about the benefits of perovskite, and this natural product can also be used to create more efficient and economically accessible solar panels. Solar panels made with perovskite can be lighter, more flexible and easier to produce compared to conventional panels, which are usually made from silicon. This fact implies the possibility of having more solar energy in different locationsthus contributing to the generation of electricity in an environmentally friendly way, without causing any kind of pollution.
What are tandem solar cells and how do they work?
Tandem cells are like a team of solar experts working together. Each layer of cells is specialized in capturing a different part of sunlight, as if each layer had its own receptor. When they come together, they make optimal use of sunlight and convert it into electricity more efficiently. It’s akin to forming an unbeatable team to make the most of the power of the sun. These two layers manage to convert more sunlight into electricity compared to when just one layer works separately, resulting in higher costs and longer working times.
