Germany wraps up ‘innovative’ tender with average price of €0.0833/kWh

Germany has concluded a new renewables tender, securing 512 MW of capacity at an average price of €0.0833 ($0.089)/kWh.

Statkraft signs ‘first-of-a-kind’ PPA with UK developer Luminous Energy

Generator enters agreement on solar plant which is also subject to a virtual corporate PPA and a fixed-price contract secured through the UK government’s Contracts for Difference auction mechanism.

Semi-transparent PV window based on passive radiative cooling coating

Scientists have manufactured and analyzed a novel coating for semi-transparent photovoltaic glazing that reportedly offers remarkable energy yield and a low heat gain rate. Through outdoor experiments, the researchers also found the glazing also provides satisfactory high-quality indoor lighting conditions.

Perovskite solar cell based on electron-rich surface passivation layer achieves 23.27% efficiency

Chinese in China have utilized two sulfone-based organic molecules known as diphenylsulfone (DPS) and 4,4′-dimethyldiphenylsulfone (DMPS) to passivate absorber defects in perovskite solar cells. The result is a device with a higher electron cloud density at the interface between the perovskite material and the passivation layer.

All solar cell efficiencies at a glance – updated

The research group led by Professor Martin Green has published Version 64 of the solar cell efficiency tables. There are 19 new results reported in the new version.

New diode equation can improve solar thin-film efficiency, researchers claim

Scientists in the United Kingdom and Finland publish a new model for analyzing thin-film and other PV devices with low charge-carrier mobilities. It’s claimed the unified diode equation for thin-film PV provides insights into the mechanisms driving limiting charge collection and power-conversion efficiency in low-mobility PV devices.
