Solar geometry-based model to assess performance of bifacial PV systems

Scientists in India utilized solar geometry to create a novel energy estimation model that reportedly accurately predicts both the front and back irradiance of bifacial PV modules. The model achieved correlation coefficients of 1.04 and 1.40 for the front and rear side, respectively.

Spanish railway operator builds 20 MW solar plant for train traction

Renfe says it will invest around €27 million ($28.4 million) to build a 20 MW pilot PV installation. It will be part of a broader project involving several PV installations along its rail network.

Low-temperature processes to reduce silver use in tandem perovskite-silicon solar cells

Researchers from Germany’s Fraunhofer ISE developed new techniques to reduce silver consumption in tandem perovskite silicon solar cells and heterojunction silicon PV devices. The new processes relate to cell metallization and module interconnection.

US set to install 66 GW of storage in 2023-27 period, says WoodMac

Wood Mackenzie says that US developers installed 1.7 GW/5.6 GWh of new storage capacity in the second quarter of 2023.

Self-interest key to maximizing rooftop solar installations

Researchers in Switzerland have found that the most effective way for governments to nudge homeowners into installing rooftop solar PV sytems hinges on individuals being told how much money they’ve lost by not getting it sooner.

SolarWatt launches TOPCon module production

SolarWatt has started production of TOPCon modules, with plans to manufacture both glass-glass and glass-backsheet versions. It says it aims to make its first shipments in January 2024.

New perovskite solar cell design with silicon dioxide anti-reflector layer

Researchers in Iran have designed a new light trapping (LT) structure for perovskite solar cells that reportedly achieves optimal light absorption without impacting the electrical properties of the cells. The key element of the device is an anti-reflector layer based on silicon dioxide (SiO2) that improves light harvesting and charge extraction performance.
