Researchers in Saudi Arabia have developed a solution to overheating solar panels that requires zero electricity. This development can also double as a method for atmospheric water collection, an important practice in dry regions, as relayed by SciTechDaily.

The research, led by King Abdullah University of Science and Technology professor Qiaoqiang Gan, is important because it addresses the problem of overheating solar panels in particularly hot and sunny regions, such as Saudi Arabia.

Existing perovskite solar cells, which have the problem of not being able to utilize approximately 52% of total solar energy, have been developed by a Korean research team as an innovative technology that maximizes near-infrared light capture performance while greatly improving power conversion efficiency. This greatly increases the possibility of commercializing next-generation solar cells and is expected to contribute to important technological advancements in the global solar cell market.

The research team of Professor Jung-Yong Lee of the School of Electrical Engineering at KAIST (President Kwang-Hyung Lee) and Professor Woojae Kim of the Department of Chemistry at Yonsei University announced on October 31st that they have developed a high-efficiency and high-stability organic-inorganic hybrid solar cell production technology that maximizes near-infrared light capture beyond the existing visible light range.

The research team suggested and advanced a hybrid next-generation device structure with organic photo-semiconductors that complements perovskite materials limited to visible light absorption and expands the absorption range to near-infrared.

Mimicking how plants convert sunlight into energy has long been a dream for scientists aiming to create renewable energy solutions. Artificial photosynthesis is a process that seeks to replicate nature’s method, using sunlight to drive chemical reactions that generate clean energy. However, creating synthetic systems that work as organically as natural photosynthesis has been a significant challenge until now.

“The first involved integrating the hole-selective materials and the perovskite layers, to simplify the manufacturing process. The second involved replacing traditional organic materials, such as fullerene and bathocuproine, with tin oxide, an inorganic electron transport layer, in a process known as the atomic layer deposition method,” per PV’s description.

Labspeak aside, the big takeaway is that the changes resulted in a 25% efficiency, meaning the cells can turn a quarter of the sunlight hitting them into energy. What’s more, they maintained 95% of their efficiency after 2,000 hours of operation, per the report.

An international research team has fabricated a 1 cm² perovskite-silicon tandem solar cell that utilizes a top cell based on a perovskite absorber integrating inorganic copper(I) thiocyanate (CuSCN).

A co-deposition strategy of CuSCN and perovskite is firstly developed to solve the key technical…

A Saudi-Chinese research team has fabricated a perovskite-silicon tandem solar cell without a hole transport layer (HTL) in the perovskite top cell. This innovative strategy, based on the co-deposition of copper(I) thiocyanate and perovskite in the top cell absorber, was intended at solving typical issues of HTLs in tandem devices.
