Inverted perovskite solar cell with antimony-doped tin oxides achieves 25.7% efficiency

Researchers in Singapore have built an inverted perovskite PV device with a p-type antimony-doped tin oxides (ATOx) interlayer that reportedly reduces the efficiency disparity between small and large-area perovskite cells. According to their findings, ATOx may easily replace commonly used nickel oxides (NiOx) as a hole transport material.

Singaporean startup unveils high intensity illumination tech that ‘rejuvenates’ solar panels

NTU Singapore researchers and startup EtaVolt presented a high intensity illumination device that can reportedly “patch up” the holes caused by light and heat in silicon solar cells. The new technique is claimed to reduce solar module degradation by up to 5 years and to be usable for around 90% of the solar modules available in the market.

Scientists achieve 29.9% efficiency for four-junction perovskite-CSI tandem solar cell

Achieved by scientists led by the National University of Singapore, the result is the highest efficiency ever recorded for a perovskite-CIS tandem solar cell at the research level to date. The researchers used methyldiammonium diiodide (MDADI) to reduce open-circuit voltage losses in the top perovskite cell.

The ‘next big thing’

The PV industry in Southeast Asia has come a long way since guest author Ragna Schmidt-Haupt, partner at Everoze, reported on solar financing innovation in the region more than a decade ago. In this article, she outlines five factors for success, the newest of which has the potential to become a game changer, and not only in Southeast Asia.

Single-reagent tech to reuse silicon from end-of-life PV panels achieves recovery rate of 98.9%

Scientists in Singapore developed a single-reagent approach to recover silicon in recycled PV panels that reportedly offers high recovery rates compared to double-reagent methods. The recycled silicon was then effectively reused in anodes intended for applications in lithium-ion batteries.

REC launches 470 W heterojunction solar panel with 22.6% efficiency

REC has developed a new series of heterojunction solar panels with efficiencies up to 22.6% and an operating temperature coefficient of -0.24% per degree Celsius.

Southeast Asia has technical potential to deploy over 1 TW of floating PV

A group of researchers from the US National Renewable Energy Laboratory assessed the potential for floating PV (FPV) plants at reservoirs and natural waterbodies in 10 Southeast Asian countries. It found that the overall FPV technical potential for the region ranges from 477 GW to 1,046 GW.
