Single-junction transparent perovskite solar cell achieves record-breaking voltage of 1.78 V

A research team in Germany claims to have achieved the highest open-circuit voltage ever recorded to date for a perovskite solar cell based on hybrid methylamine lead chloride (MAPbCl3). The novel perovskite absorber was fabricated with a two-step deposition method and annealing under molecular nitrogen (N2) gas inside a glovebox.

First attempt to design CIGS/SWCNT tandem solar cells promises 38.91% efficiency

Indian researchers have proposed to build tandem solar cells based on a CIGS top cell and a bottom cell relying on a single-walled carbon nanotube (SWCNT) absorber. SWCNTs were previously used in solar research as an alternative to conventional metal grid contacts or hole transport layers (HTLs), as they combine optoelectronic properties, flexibility, chemical stability, and simple transfer protocols.

PV modules now selling in Europe for €0.10/W to €0.115/W

Solar module prices could slightly increase as European warehouses reduce their panel stockpiles, says Leen van Bellen, business development manager Europe for Search4Solar, a Dutch purchasing platform for solar products. He tells pv magazine that TOPCon modules will soon overtake traditional PERC products in Europe.

Triple-junction perovskite–perovskite–silicon solar cell achieves record-breaking efficiency of 24.4%

Developed by scientists in Germany, the triple-junction cell is based on a perovskite top cell with an energy bandgap of 1.84 eV, a perovskite middle cell with bandgap of 1.52 eV, and a silicon bottom cell with a bandgap of 1.1 eV. The device achieved an open-circuit voltage of 2.84 V, a short-circuit current of 11.6 mA cm–2, and a fill factor of 74%.

BloombergNEF says global solar installations could hit 574 GW this year

BloombergNEF says in a new report that developers deployed 444 GW of new PV capacity throughout the world in 2023. It says new installations could reach 574 GW this year, 627 GW in 2025, and 880 GW in 2030.

Green hydrogen, power generation tech based on compressed air storage, solid-oxide electrolysis cells

Scientists in Korea have developed a compressed air storage system that can be used as a combined cooling, heat, and power system and provide heat and power to solid-oxide electrolysis cells for hydrogen generation. It showed an overall roundtrip efficiency of 121.2% and over-unity efficiencies in the range of 100% to 120%.

SEG Solar unveils 700 W TOPCon solar modules with 22.53% efficiency

SEG Solar says its new panels have a temperature coefficient of -0.30% per C. They come with a 30-year power output guarantee for 87.4% of the initial yield.

Malaysian researchers claim reflectors for PV modules are feasible

The research team tested a PV system prototype with a mirror reflector and found it could be economically feasible “under Malaysian climatic conditions.” Their analysis was based on the cost-effectiveness factor (FCE), which is a parameter that must be considered when designing an enhancer such as a reflector or a cooling technology in PV systems.

Saudi Arabia reveals bidders for 3.7 GW solar tender

Saudi Power Procurement Co. (SPPC) has announced the selected bidders for the the fifth round of the Saudi Arabian government’s renewable energy tender program.

LG launches new residential storage solution

LG has developed two versions of its new enblock E storage system, each with usable energy capacities of 12.4 kWh and 15.5 kWh. It says the two models, sized at 451 mm x 330 mm, can be easily deployed in small spaces.
