Shedding light on tandem perovskite solar cell progress

Perovskite PV devices are set to become the next big thing in solar with market analysts at S&P Global Commodity Insights predicting 1 GW of production by the end of 2024, rising to 6 GW in 2025. Perovskite tandem devices are at the front of the queue for commercialization but their characterization presents technical challenges.

Global polysilicon prices hold steady, China polysilicon falls on weak demand

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.

Hybrid hydrogen-battery system for off-grid PV-powered homes

Conceived by a Dutch research group, the proposed system is intended to store surplus renewable electricity via hydrogen generation and battery storage, with the latter being used only when hydrogen generation is not immediately available. Despite its high initial costs, the system can reportedly offer stable operation.

PERC solar products hard to sell due to falling TOPCon module prices

Prices for tunnel oxide passivated contact (TOPCon) solar panels continue to fall. pvXchange.com founder Martin Schachinger explains how this will affect the sale of PV modules based on passivated emitter and rear cell (PERC) cells.

Renewables must triple by 2030 to hit net-zero by 2050, says BloombergNEF

BloombergNEF says in a new report that solar and wind must drive most emissions cuts before 2030 to stay on track for net-zero by 2050. Its net-zero scenario targets a combined solar and wind capacity of 31 TW by 2050.

EPFL unveils perovskite-silicon tandem solar cell with certified efficiency of 30.9%

The tandem solar cell is based on a perovskite top cell treated with an additive known as 2,3,4,5,6-pentafluorobenzylphosphonic acid (pFBPA), which reportedly improves its power conversion efficiency and fill factor. The tandem device also integrates a bottom heterojunction silicon cell made with a 190-μm-thick, 2 Ω.cm, n-type, float-zone, shiny-etched monocrystalline wafer.

All-perovskite tandem PV cell based on carboranes hits 27.2% efficiency

Researchers have developed a thermal regulation strategy to improve the performance of inverted tin-lead perovskite tech for all-perovskite tandem solar cells. It has an efficiency of 23.4% and contributed to a 27.2% efficiency in a tandem cell while ensuring stability.

Silfab Solar secures funds to develop US-made back-contact n-type PV cells

Silfab Solar is one of seven recipients of US Department of Energy (DoE) funding for projects that will rely on dual-use PV technologies to electrify buildings, decarbonize the transportation sector, and reduce land-use conflicts.

Global solar and wind generation will soon pass nuclear, hydro

In a new monthly column for pv magazine, the International Solar Energy Society (ISES) explains how solar and wind are dominating power plant construction.

IEA-PVPS launches action group on agrivoltaics

IEA-PVPS is poised to launch a new format for expert engagement. It will include an action group on agrovoltaics, as well as a collaborative effort to match agriculture and solar generation. It aims to unlock the potential of agrivoltaics, optimize land use efficiency, enhance agricultural resilience to climate change, and foster social consensus for solar development.
