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.
The Hydrogen Stream: Malaysia, Singapore mulling hydrogen pipeline
City Energy and Gentari have agreed to study the feasibility of building a hydrogen pipeline from Malaysia to Singapore.
REC rolls out new 470 W rooftop solar panels
Singapore-based PV module manufacturer REC Group has launched in Australia a new series of rooftop solar panels with power ratings ranging from 450 W to 470 W and efficiencies of up to 22.6%.
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.
New mooring system for offshore, coastal floating PV arrays
The novel mooring solution consists of perimeter pontoons, barriers, clump weights, mooring lines and anchors. Its creators claim it is cheaper in materials and maintenance, as well as more wave-stable, compared to mooring systems using elastic cables.
Singapore researchers set 24.35% efficiency record for perovskite PV cell
Scientists in Singapore have achieved a world record efficiency of 24.35% for a 1 cm² inverted perovskite solar cell. The latest version of the “Solar Cell Efficiency Tables” includes the result.
Maxeon, Samsung to integrate heat pumps with residential PV
Maxeon and Samsung have developed a cloud-to-cloud system to transmit data from Maxeon’s PV panels and batteries to Samsung’s home platform. The heat pump integration enables the use of surplus PV energy to preheat rooms at specific times.
