First attempt to build thin-film solar cells relying on absorber made of silver, barium, titanium, selenium
An international research team has demonstrated, for the first time, the technical feasibility of solar cells relying on absorbers made of silver, barium, titanium, and selenium (Ag2BaTiSe4). The simulations showed these devices may reach efficiencies of up to 29.8% and be based on different buffer layer materials.
Australian grid operator turns to solar-powered microgrids
New South Wales electricity distributor Ausgrid is exploring the potential of solar-powered microgrids to enhance energy security for communities during extreme weather events.
Hybrid optimization MPPT tech for PV systems under partial shading
Researches in India have used the adaptive network-based fuzzy inference system (ANFIS) and the grey wolf optimization (GWO) algorithm to develop an MPPT technique that reportedly increases the PV source voltage of an array under partial shading conditions.
Mibet debuts ballasted wind-deflecting mounting system for flat roofs
The new product is made with AL6005-T5 aluminum combined with galvanized aluminum-zinc and offers three load-bearing options. It can reportedly be utilized in concrete roofs, flat grounds and membrane roofs and withstand a wind load of 45m/s and a snow load of 1.6KN/m2.
US startup offering UL-certified vertical PV systems
Sunstall has developed a vertical PV system that facilitates energy production in space-limited areas. It is the first system of its kind to secure certification from Underwriters Laboratories (UL) for the US market
Johnson Controls unveils water-to-water screw heat pump
US-based Johnson Controls says its new screw heat pump is able to deliver high-temperature hot water as high as 80 C. The system reportedly has a combined coefficient of performance of 4.1.
US solar sites linked to higher levels of insects
Scientists conducting a five-year research project in southern Minnesota have observed a tripling of insect numbers near two solar facilities built on rehabilitated agricultural land. They say the findings show how habitat-friendly solar could help protect insect populations and improve pollination in nearby agricultural fields.
Tibo Energy secures funds to expand sales of cloud-based software supporting C&I assets
Netherlands-based Tibo Energy has raised €3 million from European early stage investors. Its software is used by businesses to manage and optimize their renewable energy assets and grid usage.
S-5! offers solar attachment solution to simplify wire management
S-5! has introduced a module-level power electronics (MLPE) mount for solar developers, installers, end users, and engineering, procurement and construction (EPC) contractors who are looking for an MLPE mounting device for solar module frames, without attaching to rails.
Electronic circuit for PV hotspots mitigation
An international group of researchers has developed an electronic device that is said to effectively mitigate hotspots in PV modules. It uses two current comparators, two NPN transistors, and a current mirror circuit to identify anomalies in the current flow and enable precise control of the input and output current via a purely resistive element.
