Researchers develop semi-transparent perovskite solar cells with 21.68% efficiency

Researchers from the Korea Institute of Energy Research (KIER), Korea Research Institute of Standards and Science, Jusung Engineering and the Jülich Research Center have reported an advancement in the stability and efficiency of semi-transparent perovskite solar cells.

The semi-transparent solar cells achieved an impressive efficiency of 21.68%, which is said to be the highest efficiency to date among perovskite solar cells that use transparent electrodes. Additionally, they showed remarkable durability, with over 99% of their initial efficiency maintained after 240 hours of operation.

Netherlands reveals details of incentive scheme for PV manufacturing

The Dutch government has drafted a public proposal to support the production of heterojunction and perovskite-silicon tandem modules, as well as building- and vehicle-integrated PV panels, with a maximum allocation of €70 million ($75.1 million) per solar manufacturing project. Rijksdienst voor Ondernemend Nederland (RVO), the state-run agency that manages the SDE++ program for renewable energy in the Netherlands, has publicly proposed the idea of supporting the production of solar panels, storage systems and electrolyzers. The new incentive scheme, “Investeringssubsidie maakindustrie klimaatneutrale economie” (IMKE), will fund a portion of the capital expenditure needed to build factories for the three clean energy technologies.

The RVO said that the incentives for the production of PV panels will be limited to products for building-integrated (BIPV) and vehicle-integrated (VIPV) applications, as well as heterojunction modules or perovskite-silicon tandem panels.

CubicPV terminates plans for U.S silicon wafer factory

In December 2022, CubicPV announced plans to establish 10 GW of conventional mono wafer capacity in the United States. Now, CubicPV said it has halted its plans to build a major U.S. silicon wafer factory, citing a collapse in product prices and soaring construction costs. It was reported that the Company will instead be focusing on producing tandem perovskite solar modules.

As part of its restructuring scheme, the company reduced its workforce and eliminated positions tied to the U.S. factory effort. The Company said it would support the affected workers by providing severance packages and extended health benefits.

Shenzhen Hiking PV to set up perovskite-silicon tandem PV factory

Shenzhen Hiking PV has announced plans to set up a joint venture with a state-run investment company to build gigawatt-level perovskite/polysilicon tandem cell and panel production lines in a new factory in Zhongshan, Guangdong province, China. 

The factory is planned to have a total capacity of 7 GW of perovskite/polysilicon tandem cells, with an investment of CNY 5 billion (around USD$700 million). The plan is to build the plant in three phases.

Oxford PV and Fraunhofer ISE announce full-sized tandem PV module with 25% efficiency

A research team from the Fraunhofer Institute for Solar Energy Systems ISE has reported a PV module using perovskite silicon tandem solar cells from Oxford PV with an efficiency of 25% and an out-put of 421 watts on an area of 1.68 square meters, stating it is a record efficiency for a silicon perovskite tandem solar module in industrial format. 

For the manufacturing process, the researchers used equipment at Fraunhofer ISE's Module-TEC that is already used in mass production and optimized the processes for the tandem technology.

Researchers fine-tune the use of C60 ETLs for better perovskite solar cell technology

Researchers from King Abdullah University of Science and Technology (KAUST), Princeton University, Marmara University, Academy of Sciences of the Czech Republic and Nano-C have designed a perovskite-silicon tandem solar cell with a top inverted perovskite cell relying on an electron transport layer (ETL) made of thermally evaporated buckminsterfullerene (C60).

In the “p-i-n” device structure, hole-selective contact p is at the bottom of intrinsic perovskite layer i with electron transport layer n at the top. Conventional halide perovskite cells have the same structure but reversed – a “n-i-p” layout. In n-i-p architecture, the solar cell is illuminated through the electron-transport layer (ETL) side; in the p-i-n structure, it is illuminated through the hole‐transport layer (HTL) surface.

Researchers develop tandem perovskite light-emitting diodes

Researchers at Seoul National University and Korea Advanced Institute of Science and Technology (KAIST) have developed highly efficient tandem perovskite light-emitting diodes (PeLEDs). This advancement may expedite the commercialization of perovskite light-emitting materials in next-generation display technologies.

The Ministry of Science and ICT (MSIT) announced that the team, led by Professor Lee Tae-woo from Seoul National University’s College of Engineering, has successfully created a high-efficiency and long-life hybrid tandem light-emitting device. This device combines metal halide perovskites with organic light-emitting diodes.
