Perovskite solar cell with 24.33% efficiency via ionic liquid capping layer
Developed by scientists in China, the cell achieved an open-circuit voltage of 1.192V, and a fill factor of 80.67%. Its perovskite capping layer was treated with a special ionic liquid that had a positive influence on both the device’s efficiency and stability.
Chinese PV Industry Brief: Jinko switches on 8 GW TOPCon factory, Tongwei announces skyrocketing profits
Solar manufacturer JinkoSolar announced on Wednesday that its 8 GW TOPCon cell factory in the Anhui Province has started manufacturing activities. Polysilicon supplier and solar cell maker Tongwei announced on Thursday it expects to achieve a net profit of up to RMB 8.5 billion ($1.33 billion) with a YoY increase of around 136%.
Solar-plus-storage for aquaculture aeration
Recent research from Thailand has shown that solar-plus-storage on floating platforms could be the cheapest option to power energy-intensive aeration systems in aquaculture projects. The battery accounts for around 54% of the capital costs, which is why system sizing would be key for economic viability.
New tech to reduce mechanical stress in floating PV arrays
French start-up HelioRec has developed a new floater that can contain water to add more weight and increase its stability on the water. According to its creators, the new product can be 3.5 times more stable than conventional blow-molded floaters.
Lowering solar module temperatures with radiative cooling, heat pipes
Chinese scientists have developed a hybrid cooling technique to reduce module temperatures by up to 12.86 C and increase power yields by 7.25%. Their system features a PV module and a separate RC module, integrated with a flat plate heat pipe in between.
Solar-powered hydrogen for domestic applications via building-integrated transparent platform
An international research group has created a closed-loop, transparent energy platform based on PV power generation and hydrogen production from photo-electrochemical cells. The system is claimed to supply power without interruption and to be transparent enough to be integrated into buildings.
Mercedes’ newest electric car comes with thin crystalline solar cells on the roof
The solar roof was developed in collaboration with the Fraunhofer Institute for Solar Energy Systems.
PV-assisted heat pump module facade for power supply, heating, cooling, and ventilation
Designed by scientists in Germany, the module facade has to be integrated with a building’s technical equipment. The rooms behind the facade can be supplied with solar power and at the same time heated, cooled and ventilated.
Novel design for shingled solar modules
Researchers in Singapore have created a flexible framework for designing hotspot-resistant shingled modules. Their work is claimed to be perfectly compatible with existing manufacturing techniques.
GAF Energy launches Timberline nailable solar tile
GAF Energy manufactures its Timberline solar tiles at a new facility in California. It claims that the Timberline Solar roof system is unique because it directly integrates solar technology into traditional roofing processes and materials.
