Photovoltaic modules based on perovskite silicon tandem solar cells have the potential to achieve higher efficiencies than today's silicon modules. A research team at Fraunhofer ISE has now produced a module with an efficiency of 25 per cent using perovskite silicon tandem solar cells from Oxford PV.
For his YouTube channel Undecided with Matt Ferrell, the renewables youtuber goes for a deep dive of the latest and upcoming developments in perovskites and tandem solar cells:
FuturaSun will showcase various innovative products at Key Energy trade fair in Rimini from 28 February to 1 March.
During the 6th China International PV Industry Conference (Chengdu, China, 13-16 November 2023), Martin Green, Professor at the University of New South Wales, Australia, shared his view that IBC technology (Interdigitated Back Contact) will dominate the industry landscape. Here’s how:
Tandem solar cells based on perovskite semiconductors can convert sunlight into electricity more efficiently than conventional silicon solar cells. In order to bring this technology to the market, stability and production processes must be further improved. Artificial intelligence (AI) methods could now help with production.
With a new solar simulator, it is now possible to precisely determine the output of tandem solar cells. In a first step, the developers designed the system for perovskite-silicon tandems.
The tandem of silicon solar cell and a layer of metal halide semiconductor already achieves high efficiencies in the laboratory. This efficiency is now to be transferred to mass production.
Scientists have developed a prototype for scalable perovskite tandem solar modules. These modules achieve an efficiency of up to 19.1 per cent on an area of 12.25 square centimetres. The researchers hope for high market shares for tandem modules in the future.
A study has evaluated the environmental impact of industrially manufactured perovskite-on-silicon tandem solar modules over their entire service life. Result: The tandem solar modules are even more environmentally friendly than conventional silicon heterojunction modules.
At the research facility, the ZSW combines perovskite solar cells with various other semiconductors. In this way, the researchers want to accelerate the further development of the tandem solar cell.
Q Cells has set a new world-record tandem cell efficiency of 28.7% in collaboration with researchers at Helmholtz-Zentrum Berlin using a Q.antum-based silicon bottom cell in combination with a perovskite-based top cell.
The aesthetics of a solar system is often a key reason why homeowners decide against it. Researchers at the Karlsruhe Institute of Technology have now developed coloured solar cells made of more cost-effective perovskite semiconductor material.
Researchers in Berlin have achieved an efficiency of 29.8 per cent with a tandem cell made of silicon and perovskite. Among other things, they have improved the boundary layers between the semiconductors.
The British company has installed the machinery for the factory in Brandenburg an der Havel. Now the production of the innovative perovskite solar cells can begin. The first modules could roll off the production line starting in 2022.
The topics and discussions of the 37th edition of the European PV Solar Energy Conference and Exhibition have shown once again that a sustainable energy supply is becoming ever more important. New challenges lie ahead of us, but with initiatives like the Green Deal, there is hope for Europe.
Professor Henry Snaith, Oxford PV’s Co-Founder and Chief Scientific Officer, has received the Becquerel Prize in honour of his significant contributions to the use of perovskite in solar cells.
