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 PVE300 is a turnkey solution for the determination of solar cell spectral response/

EQE (IPCE) and IQE. A range of options include mounts for substrate, superstrate or packaged devices, integrating sphere accessory for measurements of total reflectance and transmittance, a choice of single or multiple channel bias sources, including an AM1.5 matched bias source and a motorised XY stage for device mapping.

Fabrication step: Micro and nano fabrication
Purpose: Characterization of solar cell spectral response/EQE (IPCE) and IQE.
Material systems: Polymers, organics, dielectrics, metals and semiconductors
Node: Materials
Specifications/resolution: The standard spectral range of 300-1100nm, may be extended to 1800 nm and beyond

SP-300 is a 500 mA to 10 A state-of-the-art research grade potentiostat/galvanostat/EIS with remarkable specifications such as 7 mHz max frequency, floating mode, analog filtering, built-in calibration board, and stability bandwidths.

The SP-300’s modular chassis accept an optional high current/high voltage option board.

Alternatively, the SP-300 can accept a second potentiostat board (either standard or EIS) and perform as a Bipotentiostat to perform RRDE experiment. It is also a multiple user system as each channel board can be used independently by two different researchers.

Solar simulators with various tailored spectral output are used to to test a variety of samples including but not limited to solar cells, sun screen (SPF), materials photo-stability, and other samples (in-vivo or in-vitro) under controlled, repeatable, laboratory conditions.

Fabrication step: Micro and nano fabrication
Purpose: J-V curves of solar cell devices as well as long-term stability test under illumination.
Material systems: Polymers, organics, dielectrics, metals and semiconductors
Node: Materials
Specifications/resolution: Factory certified Class AAA CW solar simulator
