Quantum algorithm for photovoltaic maximum power point tracking
Researchers have developed a quantum particle swarm optimization algorithm for maximum power point tracking that reportedly generates 3.33% more power in higher temperature tests and 0.89% more power in partial shading tests compared to conventional swarm optimization algorithms.
U.S. startup develops 28%-efficient perovskite-silicon tandem solar module
U.S.-based PeroNova is specialized in metal halide perovskite-silicon tandem solar cells made with its novel stability-enhancing interfacial treatment. It is targeting a range of applications including space and rooftop markets.
Increasing voltage in cadmium telluride solar cells through nickel oxide back buffer layer
Cadmium telluride solar cells are commonly based on non-ohmic back contacts that affect the device open-circuit voltage. Researchers in the United Kingdom sought to address this issue by adding a nickel oxide back buffer layer, which formed an ohmic back contact and increased open-circuit voltage levels.
Recovering silver from PV waste via green graphene
Researchers at James Cook University have developed a process to synthesize graphene from tangerine peel oil, which they then used to recover silver from waste PV material. To demonstrate the quality of the recovered silver and the synthesized graphene, they made a dopamine sensor that reportedly outperformed reference devices.
Q-Sun Solar, Bakarat Investment to build 10 GW solar panel factory in Oman
The China-based solar manufacturer and Oman’s renewable investment entity Bakarat Investment have agreed to jointly establish a 10 GW solar module factory in the country with an investment of around $200 million.
Chinese PV Industry Brief: CEEC launches 15 GW inverter procurement plan
Inverter manufacturers such as Sungrow, Huawei, Sineng, Growatt, Kstar, and TBEA are all participating in CEEC’s procurement scheme, which aims to source around 15 GW of products.
Aerosols from wildfires slash North American solar production
In a new weekly update for pv magazine, Solcast, a DNV company, reports that, throughout July, smoke from wildfires in Canada and the US West Coast significantly impacted irradiance across North America, while Hurricane Beryl and upper atmospheric conditions delivered unstable cloud cover across the central and eastern United States.
New deterioration diagnosis tech for individual modules in PV panel strings
Conceived by scientists in Japan, the system consists of a a xenon flash lighting system and a detector capacitor. It can reportedly examine solar modules and find the degraded ones without disconnecting the string’s electrical wiring.
Chinese solar cell prices fall amid oversupply
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Dutch province invests in BIPV panel manufacturer Solarge
Limburg, the southernmost province of the Netherlands, has announced investment in solar panel manufacturer Solarge. Solarge is planning to increase production capacity at its site in Limburg and also construct a new facility.
