Researchers in Kenya are seeking to reduce the influence of the Geomagnetic field on PV panel performance by replacing aluminum module frames with a steel cage. They have specified they have been unable to quantify costs related to the solution, and that more research is needed.

Scientists in the Netherlands have claimed that a heterojunction metal wrap-through solar module they are designing could offer a 4% performance improvement over conventional heterojunction panels.

An international research group has developed a self-cooling PV system featuring a 250 W 60-cell polycrystalline module and a thermal collector attached to the back side of the panel. The cleaning tech is based on a microcontroller programmable integrated circuit, which controls a rotating DC motor.

Scientists in the U.S. have developed a new cathode chemistry for lithium-sulfur batteries, which they say promises to overcome performance issues stemming from sulfur’s low conductivity and tendency to react with lithium.

The road to cheap hydrogen production is riddled with potholes and energy losses. Researchers in Australia have demonstrated rethinking solar technology and skipping electrolysers could hold great promise for reaching the hydrogen holy grail.

Scientists in Morocco have designed a new bifacial module with a cooling system, based on bifacial parabolic solar cells that are connected to each other via tubes for panel cooling. They are now patenting the tech, but have yet to manufacture an initial prototype.

National Taiwan University and Taiwanese PV production equipment provider E-Sun Precision Industrial Co. have developed equipment to produce different kinds of perovskite cells with varying chemical compositions. The first trials achieved 14.3% conversion efficiency rates.

The spherical 3D cells can reportedly generate around 101% more power than conventional flat solar cells. Measurements have also shown that the spherical cells provide a 10% lower maximum temperature compared to flat cells, while accumulating less dust.

A team of researchers led by Nanchang University in China trialed a polymer based hole transport layer to flexible perovskite solar cells, using a glue to attach it to the active perovskite. The team was able to assemble the 19.87%-efficient cells into a small flexible module suitable for wearable solar applications, and says its design was inspired by the structure and movements of human vertebrae.

This investment comes on top of US$100 million invested in 2018. Venture capital and corporate funding of new energy technologies continues despite – or perhaps because of – the pandemic.
