More efficient large-area organic solar cells with spin coating

Researchers in South Korea have used the process to increase performance and the replicability of large-area organic cells. The method was used during film formation to speed up solvent evaporation.

How long will the lithium supply last?

Researchers have sounded the alarm. If no serious efforts are made on second-life battery use, recycling and vehicle-to-grid applications, decarbonization efforts may hit the buffers a lot sooner than expected.

NREL scientists estimate global potential of hydro-linked floating PV at up to 7.5 TW

The U.S. based researchers said linking solar with hydro in a full hybrid system configuration may result – at best – in the deployment of 7,593 GW for an estimated annual power generation of 10,616 TWh and a 20% reservoir coverage. And combining solar with hydro in this way brings further benefits, including improved system operation at different time scales, more opportunities for storage thanks to pumped hydro, increased utilization rates of transmission lines, reduced PV curtailment, and lower interconnection costs and water evaporation.

The long read: Bottom-optimization

With bifacial modules making their way into the mainstream, tracker manufacturers and energy companies are operating test facilities around the world. To drive the LCOE as low as possible, tracker manufacturers now also care about what is happening underneath the modules, and not just above. As the power comes from light reflected from the ground, increasing that reflectivity has been mooted by many stakeholders. This is not without complication, however, and the quest for optimization goes into the next round.

NREL scientists encourage ‘optimal’ PV curtailment

Solar curtailment might become a valuable aspect of future PV deployment, particularly if grid operators start focusing on ‘curtailment management’ instead of ‘curtailment prevention.’ Management would include measures such as flexible generation, storage, load flexibility, and regional coordination.

Machine-learning for PV module cleaning

French researchers have developed a machine-learning model to clean low-power PV projects and standalone solar arrays in rural areas isolated from the grid.

Over 26,000 register for World Solar Technology Summit tomorrow

The Summit will see the signing of four partnership agreements, including one between India’s Ministry of New and Renewable Energy, World Bank, and International Solar Alliance.

The long read: Storage … ready?

The story of residential rooftop solar is one of liberation. Confronted with high module prices, early PV adopters experienced significantly longer payback periods – it was not unheard of for homeowners to be making monthly finance payments higher than their utility bills. But consumers were motivated, seeking independence from the stranglehold that electricity providers had on them with ever-increasing utility rates.

Adani now the world’s largest solar power developer

India’s largest private-sector thermal power producer—which ranked as the sixth-largest solar player globally in 2019—has climbed to the top spot following a Solar Energy Corporation of India (Seci) award to develop 8 GW of Indian solar project capacity.

A solar cell so thin, it can rest on a soap bubble

Scientists at Saudia Arabia’s King Abdullah University of Science and Technology demonstrated an organic PV cell that can simply be printed onto a piece of paper. The cell set a new efficiency record for a fully inkjet-printed device, and its designers envisage applications in integrated medical sensors.
