Imec, Jolywood announce 23.2% front-side conversion efficiency for n-PERT bifacial cell

The result was certified by the solar cells laboratory at the calibration and test center of Germany’s Institute for Solar Energy Research. Imec’s measurements showed cell bifaciality surpassed 80%.

Understanding why cesium and rubidium salt improve the yield of perovskite solar cells

The addition of either salt enables more even distribution of halide atoms within the perovskite material – key to increasing cell conversion efficiency. The explanation should speed up the process of identifying the best perovskite mixes.

PV industry demand in India will help shore up silver price this year

According to the Silver Institute, demand for the precious metal in the solar industry will remain stable up to 2022, despite recent changes in China’s PV policy.

New approach to measure solar potential of urban areas could be used in all climates

Dutch researchers have come up with a system they claim has a maximum estimation error of less than 10% and which reduces the computational requirements for calculating the output of PV systems in complex environments. The approach is based on the correlation between a skyline’s profile and annual irradiation.

Singlet fission may raise theoretical efficiency of solar cells to 44%

According to a U.S. research team, new nanomaterials relying on dyes based on diketopyrrolopyrrole and rylene can generate a singlet fission reaction that extends the life of harvestable electronic charges.

Saudi Arabia launches tender for 1.5 GW of solar capacity

The Renewable Energy Project Development Office is tendering seven large-scale IPP solar projects. The exercise is part of Round 2 of the Saudi National Renewable program, which is expected to allocate almost 2.2 GW of PV capacity this year.

South Korea kicks off polysilicon duty talks with China

At the Korea-China Free Trade Agreement Joint Committee meeting, the South Korean government urged China to lift import measures against its polyoxymethylene, optical fiber, polysilicon and grain-oriented electrical steel. China imposed duties on polysilicon from South Korea and the United States in July 2013.

Indian solar is coming up on the rails of China and the US

Taiwanese market research company EnergyTrend says the 5/31 policy change in China last year had a less dramatic effect on global demand than expected and, with the Modi government introducing solar-friendly policies, India – and Japan – will close the gap on the world leaders for installed PV capacity.

PV rooftop simulators may unlock solar growth in developing cities

IRENA says technologies for 3D rooftop footprint generation and solar irradiation modelling are becoming increasingly cheap, making them suitable for deployment anywhere in the world. Developing cities could access such technical resources to plan rooftop PV development.

Indian panel data could transform PV monitoring processes

Researchers say the use of clustering-based computation could remove the need for on-site inspections of panels by instead enabling real-time monitoring of degradation using only meteorological data.
