They develop super efficient solar panels using perovskite and silicon

Researchers from the Eindhoven University of Technology in the Netherlands have created Solar panels that pass the 30% efficiency barrier Thanks to tandem perovskite and silicon devices.

These elements can achieve higher efficiency than single junction solar cells due to the use of solar spectrum.

statement issued by the university indicates that they have Perovskite solar cells combined with silicon solar cell technologies, The cell of the first mentioned material is independently certified as it has transparent contacts and provides more power.



If researchers achieve higher power densities, they’ll create more opportunities Integrate said solar cells into construction And its material, as such, would cover a large existing surface with photovoltaic modules.

Experts point out in statement that this is “a big step forward”. accelerate energy transition They have also improved the efficiency of semi-transparent perovskite cells by 19.7% over an area of ​​3×3 mm², by reducing dependence on fossil fuels”.

Mehrdad Najafi (Ph.D. from the university) explains that “this type of solar cell has a highly transparent back contact, which allows more than 93% of near-infrared light to reach the lower device. This demonstrated was achieved by optimizing all layers of the perovskite solar cells Semi-transparent images using advanced optical and electrical simulations to guide experimental work in the laboratory”.


Sunshine street on the street.

On the other hand, Yifeng Zhao (PhD student at TU Delft) states that “the silicon device is a 20×20 mm² wide heterojunction solar cell, with optimized surface passivation, transparent conductive oxides and copper-plated front contacts for next-generation carrier extraction “.

Combination of silicon-based technologies and perovskite cells provide conversion capabilities Close to 30% to demonstrate the efficiency of solar panels. Gianluca Colletti (Program Manager at TNO) concludes that they now know about the “materials needed to control the layers”. Aim to achieve more than 30% efficiency,
