Is it worth increasing cell efficiency? A new metric tells you when

A group of scientists is proposing a new metric – the value of efficiency – to calculate the maximum allowable cost to increase a cell’s efficiency and improve the levelized cost of electricity (LCOE). The researchers expect that more regional diversification may be seen at the global level in the years to come, with the proposed metric offering higher values in North America, Central and Northern Europe, Japan, Australia, and New Zealand.

New sandwich-like material for lead-free perovskite solar cells

Scientists from Purdue University claim to have created a new material that incorporates both organic and inorganic materials. Its hybrid structure is said to improve the thermal stability of perovskite PV cells without the need to use lead.

Enertronica Santerno reports higher inverter shipments in 2019

In a short conversation with pv magazine, the company’s CEO, Vito Nardi, said shipments for this year are expected to reach 866 MW. The inverter manufacturer also expects a rate of production of 2 GW per year by the end of next year.

Energyra works on restarting PV factory in the Netherlands

The insolvent photovoltaic manufacturer is still talking to potential investment partners, but it claims that it could resume PV module production at its shuttered factory in the Dutch municipality of Zaanstad on short notice.

The ‘butterfly effect’ of Chinese PV listings

A recent study shows that PV costs have declined faster than any other energy technology over the past two decades. The researcher behind the study said this would not have been possible without the “butterfly effect,” which is based on the idea that a small change in one part of a complex system can have a large impact elsewhere. The researcher also attributed the the rapidly declining cost of PV to Chinese manufacturing and strong US investor support.


Webinar Q&A: Avoiding the ‘green halo’ effect

Earlier this month, pv magazine held its first webinar under the UP sustainability initiative, looking at greenwashing versus verifiable sustainability. Initiative partner SMA and Professor Dustin Mulvaney shared their insights in a lively discussion. Many questions were submitted by the webinar participants. What follows are those we did not have time to answer.

Are rare earths used in solar panels?

A new report by the French Environment and Energy Management Agency reveals some surprises about the use of rare earth minerals in the renewable energy sector.


Vikram Solar targets US market with new PV module offerings

Vikram Solar recently announced three commercial-sized solar modules for the U.S. market – framed and frameless bifacial offerings, plus a half cut standard mono PERC panel – whose peak output ranges from 375 W through 425 W, available from January.

Webinar Q&A: Performance modelling for accurate energy output and yield prediction of bifacial PV systems

In our recent webinar, held in partnership with JinkoSolar, on the impact of bifacial modules and modelling their yield under varying environmental conditions and system setups, JinkoSolar’s Andrea Viaro discussed innovations in bifacial module design, and implementing these into a system to positively impact the return on investment. Teun Burgers, a Senior Researcher at ECN.TNO also delved into the simulation of bifacial PV systems, and treated us to a closer look at ECN’s BIGEYE simulation model. Here, the two presenters answer some more of the questions posed by the audience during the webinar.

Aleo Solar to launch 333 W module in January

German headquartered PV manufacturer Aleo Solar has announced plans to introduce the module in the new year. Like many of its rivals, the company is moving to a larger cell size for the new product, which it says will offer up to 333 W output from a 60-cell format.
