In this newsletter we cover the following
Shear thinning of jetted solder and glue for assembly
Fully printed double sided MCU on PET substrates?
Ultrafine Cu mesh for transparent conductive films for touch, heating, security, etc film applications?
Perovskite solar panels outperform the current silicon-based commercial panels, but what about cost?
Perovskite solar panels are highly promising not just for utility-grade, but also for indoor light harvesting.
Perovskite encapsulation for enhanced stability
Microdispensing quantum dots for color conversion
How will perovskite panels perform in the 'real world'?
We cover these points by sharing short (1min or so) handpicked snippets from their live recent talks at TechBlick, Future of Electronics RESHAPED and Perovskite Connect conferences and exhibitions
Join us at TechBlick’s Future of Electronics RESHAPED conference and exhibitions in Berlin on 22 and 23 OCT 2025. This is the global home of the additive, printed, 3D hybrid and sustainable electronics, bringing the entire value chain together, from innovators to suppliers and end users.
This year as a special theme we will also collocate Perovskite Connect alongside the same show

Shear thinning of jetted solder and glue for assembly
Shear thinning is one of the most important physical phenomena in jetting - or in fact in all of printed electronics! This is the physical mechanism on which much of the printed electronics industry relies! Here Irving Rodriguez from Essemtec explains this behaviour for jetting of solder as well as structural glue, showing how the shear rate increase in the jetting head leads to a drop a significant drop in viscosity
Fully printed double sided MCU on PET substrates?
Lina Kadura from CEA-Liten presented at TechBlick Innovation Day in April 2025, showing a full printed double sided MCU PCB with 4 metal layers and 100+ through vias, accommodating over 40 SMT (400um MCU pitch).
This is an incredible achievement showing that printed PCBs can lead to complex mullti-layer fully functional electronic PCBs for complex systems, showing that PCBs can be printed leading to greener solutions at lower cost?
Ultrafine Cu mesh for transparent conductive films for touch, heating, security, etc film applications?
Here Jonathan Chang from Panasonic North America explained at the TechBlick Future of Electronics SHOW USA (Boston, 2025) how they R2R form these films and what the key properties are.
Fist the grooves are embossed into PET or PEC later and then the Cu mesh is formed. The mesh has 2um linewidth and is embedded within the film, yielding a smooth surface. The pattern is customised and the R2R process can do top and bottom layers at the same time giving rise to double sided films
Perovskite solar panels outperform the current silicon-based commercial panels, but what about cost?
In April 2025, during our Perovskite Innovation Day, Utmolight's co-founder
Jesse Zheng said that while perovskites are not competitive yet, there are encouraging signs, and with a 10 GW factory, the company could reach cost parity with silicon.
Perovskite solar panels are highly promising not just for utility-grade, but also for indoor light harvesting.
In January 2024, during our Future of PV event, Halocell's Emanuele Calabró showed the superior performance of indoor light harvesting with its panels.
Perovskite encapsulation for enhanced stability
One of the key challenges that the perovskite industry still faces is the stability of lifetime of perovskite solar panels.
In April 2025, during our Perovskite Innovation Day, Intellivation's Robert Malay introduced the company's encapsulation solutions, and discussed the challenges facing perovskite solar panel makers.
Microdispensing quantum dots for color conversion
XTPL developed a unique printing technology that offers high-performance and high precision material deposition, with several possible applications in the display industry.
In December 2024, during our Display Innovation Day, XTPL presented their solution for micro bump deposition, and also presented a demonstration of QD deposition for microLED color conversion, a collaboration project with X-Display.
Perovskite materials and exciting researchers and developers all over the world, as the industry is on the verge of mass commercialization starting with solar panels.
In April 2025, during our Perovskite Innovation Day, Noctiluca's Łukasz Sytniewski explained why the company identified the perovskite solar industry as the key next market for the company, and detailed its new material R&D activities.
How will perovskite panels perform in the 'real world'?
Perovskite solar panels are highly promising, but people still wonder just how perovskite panels will perform in the 'real world'.
In April 2025, during our Perovskite Innovation Day, Microquanta's Yang Chen details the latest performance of the company's perovskite panels - showing how they generate more electricity than silicon in harsh environments.
