Technology and R&D

PV systems are unique among electronic devices, as they are expected to survive outdoors for at least 25 to 30 years. This makes module and system quality one of the cornerstones of guaranteed returns on investment. Potential-induced degradation (PID) is a critical failure mode with a potentially high financial impact. New research from imec and Hasselt University looks at the damaging impact that PID can have on bifacial technology, writes Michaël Daenen, a professor at EnergyVille and Hasselt University.

Turkish researchers have developed an algorithm to distinguish faults and changes in PV plant output. The sensorless method only uses electrical data gathered from the DC inputs of inverters. They tested it on 8.5 MW of ground-mount PV at nine sites, as well as 8.2 MW across 18 rooftops.

A numerical study by researchers at India’s Chitkara University has shown enhanced charge extraction in metal-perovskite-metal back-contact solar cell structure through electrostatic doping. The proposed design yielded a 59.4% improvement in power conversion efficiency over previously reported structures.

Solavio Labs has already held three funding rounds to support the development of its new panel-cleaning robot.

Relectrify said its new storage system is suitable for commercial and industrial applications and is designed for installations in the 120 kWh to 2 MWh range.

U.S. scientists assessed the reuse and recycling of large-format lithium-ion batteries for electric vehicles and energy storage systems and found there is plenty of room for improvement.

The mini panel has a surface of 10 cm². It was built with a manufacturing technique that is claimed to be compatible with the integration of perovskite into heterojunction silicon solar cells in tandem architecture.

The US researchers claim to have achieved the remarkable result by adding a special conductive layer of tin dioxide bonded between the conductive layer and the perovskite material. They also improved the perovskite layer special additives that do not alter the material’s bandgap.

In a U.S. study of the added renewables capacity made possible by grid-enhancing technologies, Brattle Group found that both solar and wind power would benefit in Kansas and Oklahoma through 2025.

Researchers from the Center for Solar Energy Technologies of Fraunhofer Chile have conducted a comparative analysis which shows that the lowest levelized cost of energy (LCOE ) in Chile can be achieved by a combination of large scale PV and concentrated solar power (CSP).
