solar cell

French chemical company Axcentive and solar module manufacturer Photowatt have developed a PV panel coating based on photoactive nanotechnology. The coating relies on a super-hydrophilic surface that makes the water spread out on the module surface immediately, thus avoiding light scattering effects upon rain.

Developed by scientists in China, the cell was used to fabricate a 20.5%-efficient mini perovskite module. A dual-functional additive was applied to regulate the crystallization and defects of the formamidinium-cesium perovskite film.

The result, confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH), was achieved on a heterojunction solar cell based on an M6 wafer.

Scientists in Spain have built a 10.61%-efficient tin perovskite solar cell with improved open-circuit voltage and stability. The device was fabricated with formamidinium tin iodide (FASnI<sub3), sodium borohydride (NaBH₄) as a reducing agent, and a bulky secondary ammonium cation of small size known as dipropylammonium iodide (DipI).

A Dutch-British research group is developing a 1μm crystalline silicon membrane with a remarkable optical performance and a hyper-uniform pattern design. A simulation of the device was theoretically able to achieve an absorption equivalent photocurrent of 26.3mA/cm².

US solar generation reached new heights despite a year of challenges. Plus, pv magazine discusses “renewable” vs. “sustainable.”

The announcement of a new anti-circumvention investigation brings the US solar industry closer to what has been described as a worst-case scenario for companies that account for 80% of the country’s solar cell imports, with no domestic manufacturing capacity to alleviate the pressure.

US-based IntriEnergy has secured a patent for its PV cell tech platform that can increase the energy output of solar panels by up to 60% without increasing the panel size.

The autonomous system is designed for small companies that produce milk, juice, beverages, or food products, it and can reach four degrees Celsius in three hours with an external temperature of 30 degrees.

German consultancy VDE Renewables and global reinsurer Munich Re have outlined an approach to quantify the impact of risk mitigation measures applied to PV projects, as well as the advantages that may be derived by relying on an insurance solution. Risk mitigation expert Ulrike Jahn has spoken with pv magazine on how the new approach was shaped and what kind of performance issues should be taken into account by PV asset owners.
