Perovskite solar cell built on steel substrate achieves record efficiency of 17.1%
Scientists in Australia claim to have achieved the highest efficiency ever reported to date for a perovskite solar cell built on a steel substrate. They utilized an indium tin oxide (ITO) interlayer between the steel substrate and the cell in order to avoid iron diffusion from the substrate into the PV device.
OGO Energy introduces residential battery storage solutions
India’s OGO Energy has developed modular battery energy storage systems with smart management capabilities. Up to five battery modules of 5.12 kWh each can be combined for a total storage capacity of 25.6 kWh.
The economics of storing renewables with Carnot batteries
A group of researchers in Denmark has investigated how Carnot batteries may be used to store renewable energy in their home country and have found that these devices may provide a significant contribution only under a certain cost threshold.
Solar module prices continue to fall
Although raw material costs in China are slowly stabilizing again, PV module prices continue to decline, as inventory levels remain very high.
Aims Power introduces hybrid inverter for solar-battery systems
Aims Power has developed a hybrid inverter for solar-battery systems, with power outputs of 4.6 kW and 9.6 kW and solar input capacities of 6.9 kW and 15 kW.
Chinese PV Industry Brief: Astronergy plans 2 GW offshore solar project

Liberia plans 15 MW/10 MWh solar-plus-storage project
Liberia Electricity Corp. (LEC) is seeking consultants to develop a 15 MW/10 MWh solar-plus-storage installation at Roberts International Airport near Monrovia, Liberia’s capital city.
New research shows renewables are more profitable than nuclear power
In a recent study, researchers from the European Environmental Bureau (EEB), the Stockholm School of Economics (SSE), and the Potsdam Institute for Climate Impact Research (PIK) questioned the planned development of new nuclear capacities in the energy strategies of the United States and certain European countries.
Saudi researchers apply distributionally robust optimization to wind, solar project siting
Saudi scientists created a new deep learning technique based on distributionally robust optimization (DRO) to identify the most suitable locations for utility scale wind and solar power projects. They applied the model to Saudi Arabia and found it provides ‘more realistic’ results than deterministic or robust models.
Germany allocates 1.67 GW in large-scale solar tender
Germany’s latest auction for utility-scale solar concluded with prices ranging from €0.0539 ($0.0588)/kWh to €0.0665/kWh. The procurement exercise was significantly oversubscribed.
