Solar cells that combine traditional silicon with cutting-edge perovskites could push the efficiency of solar panels to new heights.
The latest solar panel technology advancements are reshaping how we think about energy and its role in modern life, positioning solar power as an essential part of the future of sustainable energy. By streamlining the permitting and engineering process, the United States can accelerate the transition to renewable energy sources and unlock a
A new kind of solar cell is coming: is it the future of green energy? Firms commercializing perovskite–silicon ''tandem'' photovoltaics say that the panels will be more efficient and could
As our new research shows, current tandem solar cells must be redesigned if they''re to be manufactured at the scale required to become the climate-saving technology the planet needs. The most advanced silicon solar cells produced today are about as good as the technology will get.
A scientific breakthrough brings mass production of the next generation of cheaper and lighter perovskite solar cells one step closer thanks to researchers at the University of Surrey''s Advanced...
A nanoscale ''ink'' coating of aluminium oxide on metal halide perovskite improves the potential of this emerging photovoltaic technology and stabilises the drop in energy output which currently plagues perovskite technology.
"In the past, metal oxides have been shown to either benefit or degrade the performance of perovskite solar cells. We''ve identified aluminium oxide which can improve performance and minimises the drop in efficiency during conditioning of perovskite solar cells. We show that this nano-oxide allows a uniform coating of perovskite material on highly promising organic molecules that self-assemble on a surface and improve device output."
Dr Imalka Jayawardena, from the University of Surrey''s Advanced Technology Institute said:
"Performance limits of traditional solar cells are why researchers are switching to examining perovskite as the next-generation solar technology, especially as applications both terrestrial and in space are rapidly growing. Our key development in solar panel technology shows a cost-effective approach to scaling of perovskite solar cells, a development which could help countries around the world to reach their net zero targets faster."
Prof. Ravi Silva, corresponding author from the ATI, University of Surrey said:
"Solar and wind energy costs are rapidly decreasing based on technology improvements, to the level where worldwide over 80% of all new additional power generation capacity is based on renewables. The levelised cost of solar electricity is now cheaper than most other power generating sources. With the maturing of perovskite solar modules, the levelised cost of electricity will significantly decrease further, and that is why this is such an exciting area to work."
The research was published in the journal RRL Solar.

Global solar power capacity skyrocketed in 2023, leading to a rapid acceleration of clean power revolution. The solar surge is not just about the remarkable growth in China, as more gigawatt-scale solar markets are emerging and the vast potential of the sunniest countries is ready to be unleashed.
Solar skyrocketed in 2023. Installations rose by a record 147 GW – from 199 GW in 2022 to 346 GW in 2023. This meant 74% more solar was installed in 2023 than in 2022, the fastest percentage rise since 2011. Almost three-quarters of all renewable capacity built in 2023 was solar.
Wind additions also increased by a sizable 51% in 2023, accounting for another quarter of renewable capacity additions in 2023. After two years of slower growth, 2023 saw a new record for wind capacity additions, beating the previous record set in 2020. Solar capacity additions were three times that of wind, making solar the clear leader of the clean power revolution. Hydro installations fell to their lowest level since 2001.
Most of the new renewable capacity globally was installed in China but there are now 28 countries with gigawatt-scale markets, as more countries are taking advantage of cheap solar electricity.
China was responsible for 63% of the solar additions worldwide in 2023, and 65% of wind. This was a record high share and a significant increase from installing 43% of global solar additions in 2022 and 48% of wind.
China has played a pivotal role in scaling up wind and solar deployment globally, while the cost of these technologies fell with growing adoption to make them the cheapest source of electricity.
Over January-March 2024 alone, China added another 45.74 GW of new solar capacity (up from 12.08 GW the previous year) and 15.5 GW of wind, according to the National Energy Administration (NEA) of China. This brings more confidence that the renewable capacity surge in 2023 will continue.
But it''s not only China: the number of gigawatt-scale solar markets grew to 28 countries in 2023, up from 21 in 2022. More than half are in Europe, as an early technology adopter, but several front-runner countries have emerged in Latin America and the Middle East since 2017.
As solar panel prices have plummeted, more countries are taking advantage of this technology to kick off their renewables growth story and to bring cheaper power to their domestic markets.
As more solar capacity was installed in countries with below-average solar insolation, a vast potential remains untapped. Africa accounted for less than 1% of global installed solar capacity as of 2023, marking a stark disparity compared to the rest of the world.
The sunniest countries have installed the least solar. Only 14% of global solar capacity installed as of 2023 (204 GW) was in markets with solar insolation above the global average. Notably, Japan has 13 times as many solar panels per person than India and 41 times as many as Egypt despite the fact that a solar panel in these two sunnier countries would produce 32% and 64% more electricity, respectively.
This underscores the vast untapped potential in markets with higher insolation, which would lead to higher solar capacity factors. Therefore, stronger support for solar projects in countries with high potential such as India and African countries, is imperative. Unleashing their potential will benefit greatly from the dramatic reduction in solar costs, largely driven by early adopters’ support.
There is a stark regional disparity in global renewable capacity growth. Africa, despite being home to almost a fifth of the world''s population, accounted for only 0.2% of solar additions in 2023 and 0.8% of wind, adding less than 1 GW of each.
Persisting barriers such as limited access to affordable financing, have prevented African countries from taking part in the solar growth story. Enabling African countries to unleash their solar potential will help meet their growing electricity demand with clean power, while also significantly accelerating the global clean power revolution.
Thanks to the unprecedented solar capacity growth in 2023, a record-breaking 473 GW of renewable power capacity was built worldwide – a 54% increase from 308 GW in 2022. The strong growth in 2023 brought the world closer to achieving the ambitious goal of tripling renewable capacity by 2030.
Going forward, it would be sufficient to maintain the 16% average annual growth rate of capacity additions between 2002 and 2023 to achieve the global goal of tripling renewables by 2030. Maintaining this growth rate would mean that annual additions reach 1,340 GW by the end of the decade.
