Churches use energy mostly during the day, which makes them ideal buildings to deploy solar panels. Scientists in the United Kingdom have assessed the financial viability of a rooftop PV project for Bath Abbey and found that it could become profitable after 13 years.

Chinese scientists used perovskitoids as 1D and 0D capping layer materials for the cell’s perovskite layer. These materials enabled an effective and all-around passivation of the perovskite surfaces and grain boundaries, which prevents undesired Shockley-Read-Hall recombination and material degradation. The device achieved a power conversion efficiency of 24.18%, an open-circuit voltage of 1.151 V, a short-circuit current of 25.96 mA/cm2, and fill factor of 80.91%. 

Researchers in Thailand have developed an anti-reflective and anti-soiling coating for commercial solar modules that is claimed to increase power yield by over 6%. The coating has photocatalytic properties that make the organic compounds adsorbed on the solar module surface decompose, thus preparing them to be easily washed off by rainwater.

Norway’s clean energy agency Enova will increase the maximum PV system size eligible for rebates from 15 to 20 kW and the maximum subsidy amount from 1,250 to 2,000 NOK ($226.7) per kW installed. In addition, new subsidies of up to 10,000 NOK will be introduced for energy management systems that are often installed alongside solar arrays.

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.
