An international research group achieved the result on a 9 sq mm, triple-cation based, n-i-p structured perovskite cell using low solar concentration levels. Device instability, however, remains a challenge.
A study of the after-effects of the energy transition has assessed 156 nations and ranked a surprising winner. Here, energy expert Indra Overland discusses the findings of the GeGaLo Index as part of our interview examining renewables and geopolitics.
Researchers at Saudi Arabia’s King Abdullah University of Science and Technology have demonstrated a method they say could improve the stability of perovskite structures. The group found adding an organic dopant served to increase the strength of chemical bonds between organic and inorganic elements of a perovskite.
The latest study published by the International Renewable Energy Agency says the average solar electricity cost of $0.085/kWh produced by projects commissioned last year is set to fall to $0.048 next year, and $0.02-0.08 by 2030.
Renewables may be making encouraging advances in the south Asian nation but the natural gas infrastructure deal announced today by the Saudi power company at a stroke eclipses the 375 MW of solar capacity in Bangladesh and its 609 MW development pipeline.
An accelerated transition to renewables could go either way, regarding the United States’ unique geopolitical strength. According to Indra Overland – head of the Center for Energy Research at the Norwegian Institute for International Affairs – the U.S. could surrender a major advantage if it abandons fossil fuel. The nation could, however, remain dominant in the global energy sector if it continues to lead on innovation and clean energy tech-related intellectual property.
With Kuwait, Qatar and even renewables laggard Saudi Arabia following in the wake of regional clean energy pioneer the UAE, a raft of huge solar tenders is entering the Middle Eastern project pipeline. Obstacles remain to overseas project developers but significant rewards are on offer.
With a combination of scale, a growing population, outstanding irradiation, and available capital, solar PV should be a ‘no brainer’ for the Kingdom of Saudi Arabia. But early explorations of the technology have soured expectations, and progress has come in fits and starts.
According to the latest market forecast published by Wood Mackenzie, it seems that global PV installation figures will rise to 125 GW per year from 2020. Continued global capacity expansion will come in through a growing gigawatts-club.
Scientists at Saudi Arabia’s King Abdullah University of Science Technology have set a new efficiency record of 21.09% for a single crystal perovskite. The researchers say this highlights a place for the technology to develop alongside the multicrystalline versions which are progressing toward commercialization.
