The Digital Photonics Corporation (DPC) has launched the ‘SolarJet’ printer for selective emitter application of solar front contacts (c-Si). The SolarJet printer is claimed to simplify offline process feasibility by making it possible for labs to quickly, accurately and cost-effectively gauge real world performance benefits before making larger in-line investments. Once feasibility is confirmed, the system can be easily scaled up for larger print runs. The system features inkjet components from Trident Solar generating enhanced efficiency and reduced scrap rates.


Taking selective emitter processes cost effectively and within the shortest timescales can be problematic due to the significant variances in lab to fab equipment. Providing a scalable and reproducible process path is required.


The SolarJet simplifies feasibility testing by allowing for scalable and highly indicative test runs. Wafers are fed from underneath along a conveyer belt (as in typical production runs) to provide accurate production simulation. Up to three separate photovoltaic materials (such as etchants, dopants and dielectric layers) can be deposited in a single run- further simplifying and speeding testing processes. The SolarJet has a vision capture system for quality control consisting of three distinct CCD cameras that monitor the dispensed droplets and resulting lines. The system ensures adjustments can quickly and easily be made to guarantee reliable, reproducible print quality. The SolarJet has a throughput capability of 30 wafers per hour with manual loading and up to 200 wafers per hour with the auto-loading system.


Selective emitter cell design precursor to screen printing of front silver contacts.


The SolarJet system is the first in the industry to use the new ‘VersaEtch’ Etchant / n-Dopant combination material from Trident Solar as a precursor to screen printing of front silver contacts. The SolarJet printer also contains multiple inert, stainless steel Trident 256Jet-S printheads. The printheads also feature a unique repairable design – that allows the nozzle plate to be disassembled, ultrasonically cleaned and reassembled. These features allow the 256Jet-S printhead to last up to 5 times longer than alternative inkjet printheads and provide an industry leading one year warranty.

When it comes to storage, the US market exceeded a gigawatt of advanced energy storage installations (weighted towards lithium ion) at 1.46 GW, more than the previous six years in total! An exponential growth rate could see the market hit 7.5 GW p.a. by 2025. The summit will provide a wealth of content around this vital piece in the US power puzzle, with sessions dedicated to explore how companies are making money from batteries, the latest chemistries and their applications as they apply to different use-cases. We ask how investors can match ESG criteria to batteries and we will bring case studies of successful deployment and project execution onto the stage to examine how you can ensure your own projects are successful.
