Bio
Manuel Salado Manzorro received his PhD in Material Science in 2017, from Abengoa Research (www.abengoa.com) along with Pablo de Olavide University (www.upo.es), under the supervision of Prof. Shahzada Ahmad. He was recognized as the first PhD student to be awarded with the Industrial mention by the Pablo de Olavide University. The main goal of his PhD was the study and development of hybrid perovskite interfaces for the improvement in stability and efficiency of photovoltaics solar cells. His background as a Chemical Engineer and his subsequent Master degree in Nanomaterialsand nanostructures (www.unizar) were beneficial to assess and improve the processes related with the fabrication (scale-up) and development on products based on perovskites. He has written over 15 papers in peer-reviewed international journals, 2 Book chapters and he is also co-inventor of 2 patents in the field of perovskite solar cells.”

Interests and objetives
One of the key points of my PhD was the improvement in device performance and stability of perovskite based solar cells; Working on MOLEMAT (Molecularly Engineered Materials and process for Perovskite solar cell technology) project will give me the oportunity to keep understanding the kinetics of the devices, improving their stability and undertaking new techniques to elucidate the role of the different compounds in perovskite material.

The DMP-2850 allows the deposition of fluidic materials on an 8×11 inch or A4 substrate, utilizing a disposable piezo inkjet cartridge. This printer can create and define patterns over an area of about 200 x 300 mm and handle substrates up to 25 mm thick with an adjustable Z height. The temperature of the vacuum platen, which secures the substrate in place, can be adjusted up to 60°C. The DMP-2850 offers a variety of patterns using a pattern editor program. Additionally, a waveform editor and a drop-watch camera system allows manipulation of the electronic pulses to the piezo jetting device for optimization of the drop characteristics as it is ejected from the nozzle. This system enables easy printing of structures and samples for process verification and prototype creation.

MEMS-based cartridge-style print-head that allows users to fill their own fluids and print immediately with the DMP in their own laboratory. To minimize waste of expensive fluids, each cartridge reservoir has a capacity of 1.5 ml. Cartridges can easily be replaced to facilitate printing of a series of fluids. Each single-use cartridge has 16 nozzles linearly spaced at 254 microns with typical drop sizes of 1 and 10 picoliters.

Ossila’s UV Ozone cleaning system is capable of removing contamination on the surface of samples, providing you with ultraclean surfaces within minutes. By using a high-power UV light source, ozone is generated – which then breaks down surface contaminants into volatile compounds. These volatile compounds evaporate from the surface leaving no trace. This method can produce near-atomically clean surfaces without causing damage to the sample.

Fabrication step: Micro and nano fabrication
Purpose: Cleaning and modified substrates surfaces in the manufacture of organic electronics and semiconductors for application areas such as polymer photovoltaics.
Material systems: Glass, FTO substrates
Node: Materials
Specifications/resolution: UV ozone cleaner houses a 120mm x 120mm tray for positioning samples under the UV light source.

Spin-coating is used to apply uniform thin films to flat substrates. The film material is dissolved in a moderate boiling point material and applied to a substrate that is undergoing rotation, typically 500-2000 rpm. The thickness of film is determined by the concentration of the solution or dispersion and the rotation speed and spin time.

This particular spin coater is used to apply thin (100 nm) films to FTO-coated glass for the fabrication of organic electronic devices.

Fabrication step: Micro and Nano Fabrication

High-performance hotplate for temperatures up to 600°C with a very short heating-up time (600°C within 20 minutes). The extremely efficient insulation allows the appliance to also be used on working surfaces which are not heat-resistant. The insulated hinged lid has been designed to keep heat loss to the absolute minimum.

The temperature can either be controlled with a temperature or programme controller. With the temperature controller the hotplate’s complete heating surface is held at a constant selected temperature.

In addition, ovens are microprocessor controlled, with an LED display of time and temperature. Samples can be dried, under a temperature accuracy from 5°C above room temperature to 300°C, and providing remarkably short heating and recovery times as well as reproducible results.

Multiple

The thermal evaporator is a multi-source metal deposition system which allows metal coatings to be deposited either sequentially or by co-deposition, at a controlled thickness through a mask. The multi-source evaporator is built into a four port glove box, allowing sample handling under inert conditions and also incorporates a spin-coater. Passivating metal or metal oxide layers can be deposited, and complete devices can be assembled in non-oxidative conditions.

This facility enables the fabrication of a wide range of micro and nano-scale devices; target specific electrodes after further modification in a range of sensors; top electrodes in organic photovoltaic devices, contacts in organic diodes and transistors.
