Solar cell efficiencies at a glance – updated
A research group led by Professor Martin Green has published Version 60 of the Solar cell efficiency tables.
High-wattage solar modules increase risk of thermal runaway
Longi Solar outlines its high-temperature mitigation logic in designing the lower current, high-wattage Hi-MO5 solar panel series.
Thin-film flexible piezoelectric-photovoltaic cell based on selenium
Japanese scientists have developed a piezoelectric-photovoltaic cell with potential applications in indoor environments. They fabricated it on a flexible polyethylene terephthalate film with sputter-deposited ZnMgO thin film and photo-absorbing selenium as the n-type window layer and p-type layer, respectively.
Solar-powered offgrid residential unit from Japan
Japan’s Arth has designed an autonomous habitation module that produces water in places without energy and water infrastructure. The company said the residential unit could also be used as an emergency evacuation site.
REC Silicon, Ferroglobe to establish traceable US solar supply chain
Investments by Hanwha Group and the potential passage of the Solar Energy Manufacturing Act could expand US production of polysilicon and metallurgical-grade silicon.
Perovksite solar cell with 23.13% efficiency via new passivation approach
Australian researchers built a perovskite solar cell with guanidinium bromide and octylammonium bromide cations. They claim the device can achieve a higher open-circuit voltage, while exhibiting better efficiency and stability.
New solar module factory in Algeria
Zergoun Green Energy has begun production activities at its new 200 MW factory in Ouargla, southern Algeria.
Chinese PV Industry Brief: 1 GW TOPCon module supply order for JinkoSolar
JinkoSolar has scored a 1 GW PV panel order in China and Risen suspended a $758 million private placement of shares.
Photovoltaic water heater from Italy
Italian solar panel manufacturer Sunerg has developed an integrated photovoltaic water heater solution based on two resistances. The system relies on a maximum power point tracking (MPPT) controller and can work with a PV module with a power output of up to 450 W.
New photovoltaic in-roof system from Switzerland
Swiss module manufacturer Megasol has unveiled a novel rooftop PV system in two variants — full-black and translucent. The installation consists of vertical supports, a ridge profile, and solar modules.
