KAUST, Helmholtz-Zentrum Berlin present 31.2%-efficient blade-coated perovskite-silicon tandem solar cell
The perovskite-silicon tandem device has a two terminal configuration and a 2D perovskite layers at the bottom interface. It was able to retain around 80% of its initial efficiency for 1,700 h.
JinkoSolar announces new TOPCon solar modules with efficiency of 24.8%
The Chinese manufacturer said the new Tiger Neo 3.0 modules are available in two versions with outputs of 495 W and 670 W.
Trina Solar sues Canadian Solar for alleged TOPCon patent infringement
Trina Solar has filed a lawsuit against Canadian Solar in a US court, claiming patent infringement on an unspecified tunnel oxide passivated contact (TOPCon) solar cell technology.
JinkoSolar, Trina say TOPCon modules outperform p-type back-contact panels
JinkoSolar and Trina Solar have separately reported that on-field testing shows tunnel oxide passivated contact (TOPCon) solar modules outperform p-type back-contact PV modules in monthly power generation.
Optimal tilt angle for bifacial PV deployed on white-painted ground surfaces
Scientists in India have analyzed the performance of a bifacial PV module installed on a white-painted ground surface and have found a 30-degree tilt angle outperforms all other inclinations angles in terms of power output.
General Motors launches residential storage system
The US-based automotive manufacturing company said its new storage system offers the option of integrating with PV systems. It can be scaled to reach a capacity of up to 35.4 kWh, which the company said would enable approximately 20 hours of storage.
Japan’s Toyo plans 2 GW solar cell factory in Ethiopia
Tokyo-based Toyo Co. says it will invest $60 million in a new 2 GW solar cell factory in Ethiopia, to mostly serve the US market.
The impact of sodium, moisture on heterojunction PV module performance
Researchers in France have investigated heterojunction solar module reliability in damp heat environment and have found that sodium ions are the main source of degradation.
PV system sizing for 100% self-consumption
A group of researchers has proposed a new method for the sizing of PV systems that do not rely on an anti-dump system and operate without the possibility of injecting power into the grid. The novel approach requires an estimate of the annual hourly profile and the minimum power demanded, as well as the use of an irradiance meter and an electrical network analyzer.
New research shows vulnerability of TOPCon solar cells to contact corrosion
Researchers at the University of New South Wales claim to have identified new TOPCon contact degradation mechanisms that are significantly influenced by the combination of ions and aluminum-silver paste compositions. The primary degradation mechanism was a significant increase in series resistance.
