Scientists in Singapore have achieved a world record efficiency of 24.35% for a 1 cm² inverted perovskite solar cell. The latest version of the “Solar Cell Efficiency Tables” includes the result.

Scientists have completed a one-year trial of a model that calculates solar irradiation forecasts up to 24 hours in advance. Singapore’s Energy Market Authority now plans to adopt solar irradiance forecasting, as the model has an average error rate below 10% for one-hour forecasts.

A consortium of Singaporean universities and companies will study the feasibility of integrating a hybrid floating solar project with ocean, tidal, and wind capacity. If successful, the parties plan to deploy a pilot system with at least 100 MW of renewables capacity.

Researchers in the Netherlands and Singapore have measured irradiance-weighted average temperatures of floating PV systems in both countries and have compared the results with reference rooftop and ground-mounted PV systems. They have discovered that floating PV systems with open structures, which allow wind to pass beneath the modules, can provide a higher heat loss coefficient.

Researchers are seeking to understand the extent to which sudden spikes in irradiance can affect solar power plants. The preliminary findings indicate large scale PV projects are not immune to such events, especially when the spikes last longer than a minute.

Scientists led by the University of Cambridge have developed a new method to print a protective layer of copper directly onto a perovskite solar cell, providing protection to the active layer from damage often caused in later production stages. Cells using this layer were tested in various tandem combinations with silicon cells and achieved a maximum efficiency of 24.4%.

A global assessment of bifacial testing methods conducted in Singapore has endorsed the approach taken by France’s Institut National de l’Énergie Solaire.

Utilities and marine company Sembcorp Industries has secured an energy offtaker for its Tengeh Reservoir project.

A new handbook published by the World Bank and Solar Research Institute of Singapore contains advice on how to plan and build floating PV. The guide is intended to help developers with site identification; feasibility studies; finance; environmental and social issues; procurement and construction; and operations and maintenance.

The water authority of the city state wants to procure a 50 MW floating solar installation on the Tengeh Reservoir that will be operational by 2021. Details were revealed today by technical consultant DNV GL.
