Created by scientists in Korea, the shape-transformable 3D PV system is claimed to be able to increase electricity yield by 60% over a day compared to a fixed flat panel due to the shorter shadow length and the bifacial effect obtained during shape transformation. The proposed system doesn’t need any machinery to follow the sun and its developers said it would be a perfect solution for both urban and rural environments with limited space.

The country’s cumulative PV capacity reached 1.77 GW at the end of December.

The Philippines’ Department of Energy hopes to allocate 1,260 MW of solar through the procurement exercise.

An international group of researchers has achieved the highest fill factor reported for perovskite cells of any size to date. The device was fabricated with a nitrogen-doped titanium oxide (TiOxNy) electron transport layer aimed at improving charge transport between the cell’s perovskite absorber and the electrodes.

TransAlta has planned to start construction on the storage facility in March 2023 and to complete it within nine months. The 180 MW battery facility is designed to be charged by the existing Ghost Hydroelectric facility when demand is lower.

Developed by Malaysian scientists, the proposed multi-level aluminum fin heat sinks (MLFHS) were found able to reduce the module operating temperature by up to 8.45 degrees Celsius and increase power yield by up to 10.75%. The system cost was estimated at $0.60/W.

US researchers have investigated how rooftop PV systems may affect air and building temperature in urban environments and, conversely, how the urban heat island (UHI) effect may have a negative impact on PV system performance. Their work considered urban air temperature, urban air pollution, the partial shading of the PV system, soiling, building heating and cooling loads, and outdoor shade.

The new product measures 1754x1098x30 mm and weighs in at 21 kg. It features a temperature coefficient of -0.35% per degree Celsius and a power conversion efficiency of up to 21.29%.

Researchers in Portugal have tested how vanadium redox flow batteries can be integrated with rooftop PV to balance the system load to ensure firm power output. They proposed a 5 kW/60 kWh battery configuration for a 6.7 kW building-integrated PV microgrid. According to their findings, the battery can be used in different energy management strategy scenarios to better complement solar photovoltaic generation.

The module was fabricated with methylammonium lead iodide (MAPbI3) perovskite solar cells via low-cost spin coating. The panel also achieved an open-circuit voltage of 16.07 V, a short-circuit current of 69.52 mA, and a fill factor of 75.35%.
