Technology and R&D

The Chinese manufacturer and the University of New South Wales (UNSW) have improved the average cell efficiency by 0.68% through a post-cell hydrogenation process. The cell’s average open-circuit voltage increased by 7 mV from 696 to 703 mV, and the average fill factor from 82.03% to 83.07%.

With land-use concerns on the rise, large-scale solar projects are increasingly being built on everything from landfill sites to water reservoirs. Here’s an overview of the state of the art.

A Norwegian consortium led by Scatec is planning to build a hybrid hydropower-floating PV plant at an unspecified location in West Africa. Building both facilities simultaneously will help its developers define a series of parameters for proper sizing, optimization and design, and set a benchmark for future projects of this kind.

Enertrage and Sunfire want to build an electrolysis test field in eastern Germany and Hyzon Motors sold 500 hydrogen-powered electric trucks to Shanghai Hydrogen HongYun Automotive. Moreover, several partnership agreements were announced in Malaysia, Japan, the US, Australia and South Korea.

Now in its 38th year, and its second as a fully virtual event, the 2021 EU PVSEC conference revealed a solar industry and research community filled with confidence. Discussions at the event began with the expectation that demand for solar will continue to grow rapidly, and focused on the challenges of further scaling up production and deployment, and ensuring that energy systems can run smoothly with solar and wind as their main source of energy.

Developed by an Italian manufacturer, the panel is available in three versions with a power output of 100, 120, and 240 W and has a weight of 5 kg. It is encapsulated in thermoformable plastic technical polymers and can be connected in series with other modules around the same post.

Researchers in Singapore have built what they claim is the industry’s most efficient, large-area co-evaporated solar cell. According to their findings, the device has exhibited remarkable thermal stability and could reach commercial maturity within the next few years.

Scientists in Russia have developed an active cooling technique that spreads water on both sides of the module and uses a cotton wick mesh to absorb and spread the water that comes on the rear side. The system is able to reduce significantly a module’s operating temperature and lead to an overall improvement of 30.3% in its output power.

SunDrive said it has created the most effective commercial-sized silicon solar cell in the world, achieving an efficiency figure of 25.54% in testing carried out by Germany’s Institute for Solar Energy Research (ISFH).

Does higher energy production outweigh an increase in costs? Clean Energy Associates tries to answer this question in a new case study.
