New study looks at Sundrive’s 25.54% silver-free heterojunction solar cell
A new scientific paper takes a closer look at the record-breaking efficiency that Australia’s Sundrive announced for a silver-free heterojunction cell in September 2021, as certified by Germany’s Institute for Solar Energy Research.
Talesun, ARTsolar open 325 MW module factory in South Africa
Talesun has opened a new production facility with ARTsolar to manufacture high-efficiency, large-format PV modules. They said they might install a second 500 MW production line in the near future.
Singapore to adopt solar forecasting model
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.
Prefabricated BIPV wall for multi-floor buildings
Scientists in Singapore have built a plug-and-play, multi-layered, building-integrated PV wall that can be installed without scaffolds. The system has a light-gauge steel support structure, with a system to block air and rainwater at the wall connection.
Optimized business model for agrivoltaics
BayWa r.e. has started optimizing its sheep count while experimenting with shepherd partnership business models.
Rooftop-mounted microgrid combines wind, solar, storage
Hover’s first 36 kW installation survived the recent Hurricane Ian storm system that ravaged southwestern Florida.
EU raises concerns about production requirements in US Inflation Reduction Act
The European Union and the United States are seeking a solution for key aspects of “discriminatory” production requirements in the US Inflation Reduction Act (IRA). The EU said it might bring the case to the World Trade Organization if a compromise cannot be reached.
Chinese PV Industry Brief: Shenzhen Energy to start PV-powered hydrogen production
Shenzhen Energy has announced plans to build a green hydrogen facility in Inner Mongolia, and Daqo has secured another polysilicon supply deal. DKEM, meanwhile, has unveiled plans to build a silver paste production facility for TOPCon products.
Inverted perovskite solar cell with 21.85% efficiency via surface modulator
A UK research group has used surface modulators to reduce non-radiative recombination in perovskite solar cells. They used 2-TEAI organic halide salt to build a cell with high power conversion efficiency and stability.
New standardized guidelines for solar O&M
IEA-PVPS has standardized guidelines for O&M programs for large-scale solar plants. It defines O&M performance indicators and standard O&M operator services, as well as tools to analyze PV plant performance and safety.
