Hot charge extraction to push perovskite efficiency

With the absorption of ‘hot’ charges, which lose their energy faster than it can be absorbed by any convention technology, solar cells could become massively more efficient. An international group of scientists has developed a method to examine the bond between a perovskite and charge extraction layer, and determine the most suitable materials for hot charge extraction in a solar cell.

Hot news on harvesting electrons in perovskites

An international research group claims to have developed a new bulk perovskite semiconductor material that can capture the excess energy of hot electrons. The material is said to rapidly absorb as heat energy which would otherwise be wasted. With the harvesting of hot electrons, the maximum theoretical efficiency for hybrid-perovskite solar cells could increase from 33% to 66%.

Put your hands on a floating PV system

A new handbook published by the World Bank and Solar Research Institute of Singapore contains advice on how to plan and build floating PV. The guide is intended to help developers with site identification; feasibility studies; finance; environmental and social issues; procurement and construction; and operations and maintenance.

E-waste company opens battery recycling plants in Singapore and France

TES issued a press release announcing the new facilities that is light on detail but claimed the plants would position it as ‘a leader’ in battery recycling. The company also announced an intent to move into the reuse of spent electric vehicle batteries in commercial and residential applications.

A carbon scaffold to boost lithium-sulfur performance

Scientists at Singapore’s Agency for Science, Technology and Research have developed a new method to produce lithium-sulfur based cathodes which exhibit stable performance and high storage capacity over 200 cycles. According to the agency, this represents “a promising step towards the commercialization of lithium-sulfur batteries.”

REC kicks off production of new Alpha Series panels in Singapore

With the 600 MW production line the company’s annual module production capacity will approach 2 GW.

Australian tech billionaire to help fund 10 GW Sun Cable Project

Mike Cannon-Brookes, co-founder of software company Atlassian Corp, announced on the sidelines of the UN Climate Action Summit in New York he will help fund the ambitious 10 GW, AU$20 billion, Sun Cable Project in Australia’s Northern Territory.

Singapore preps SE Asia’s ‘largest public floating solar tender’

The water authority of the city state wants to procure a 50 MW floating solar installation on the Tengeh Reservoir that will be operational by 2021. Details were revealed today by technical consultant DNV GL.

Joining the high-efficiency gang

In a conversation with pv magazine, REC vice-president for sales in the EMEA region Ivano Zanni describes the new strategy of the Norwegian manufacturer following the launch of its high-efficiency, half-cut mono n-type heterojunction module. REC expects annual production capacity for the panels at its factory in Singapore to increase to 600 MW by the end of next year, and that the company’s total capacity will reach 2 GW.
