“…Indeed, it has often been observed in perovskite cells that bulk recombination is dominant at the highest light intensities, and that underlying mechanisms are only apparent when studied over a range of conditions.

“…At higher intensities it was not possible to resolve the additional faster process. Indeed, it has often been observed in perovskite cells that bulk recombination is dominant at the highest light intensities, and that underlying mechanisms are only apparent when studied over a range of conditions . This double exponential behavior has been linked to the presence of interfacial recombination, either at the ETL or HTL contacts .…”

Perovskite solar cells (PSCs) have gained increasing interest for space applications. However, before they can be deployed into space, their resistance to ionizing radiations, such as high-energy protons, must be demonstrated. Herein, the effect of 150 keV protons on the performance of PSCs based on aluminumdoped zinc oxide (AZO) transparent conducting oxide (TCO) is investigated. A record power conversion efficiency of 15% and 13.6% is obtained for cells based on AZO under AM1.5G and AM0 illumination, respectively. It is demonstrated that PSCs can withstand proton irradiation up to 10 13 protons cm À2 without significant loss in efficiency. From 10 14 protons cm À2 , a decrease in short-circuit current of PSCs is observed, which is consistent with interfacial degradation due to deterioration of the Spiro-OMeTAD holes transport layer during proton irradiation. The structural and optical properties of perovskite remain intact up to high fluence levels. Although shallow trap states are induced by proton irradiation in perovskite bulk at low fluence levels, charges are released efficiently and are not detrimental to the cell's performance. This work highlights the potential of PSCs based on AZO TCO to be used for space applications and gives a deeper understanding of interfacial degradation due to proton irradiation.

“…Furthermore, the combined use of screen-printing and mechanical scribing unlocks the possibility to produce modules in large scale with low-capital cost. This is because functionalized glass substrates with patterned FTO and bLayer are commercially available [27], whereas the further layer depositions of mTiO 2 , mZrO 2 and carbon and the relative P2 and P3 scribes can be carried out via inexpensive techniques, i.e., screen-printing and mechanical scribing.…”

The fully printable carbon triple-mesoscopic perovskite solar cell (C-PSC) has already demonstrated good efficiency and long-term stability, opening the possibility of lab-to-fab transition. Modules based on C-PSC architecture have been reported and, at present, are achieved through the accurate registration of each of the patterned layers using screen-printing. Modules based on this approach were reported with geometric fill factor (g-FF) as high as 70%. Another approach to create the interconnects, the so-called scribing method, was reported to achieve more than 90% g-FF for architectures based on evaporated metal contacts, i.e., without a carbon counter electrode. Here, for the first time, we adopt the scribing method to selectively remove materials within a C-PSC. This approach allowed a deep and selective scribe to open an aperture from the transparent electrode through all the layers, including the blocking layer, enabling a direct contact between the electrodes in the interconnects. In this work, a systematic study of the interconnection area between cells is discussed, showing the key role of the FTO/carbon contact. Furthermore, a module on 10 × 10 cm2 substrate with the optimised design showing efficiency over 10% is also demonstrated.

“…Despite the difficulty it entails, several deposition processes are being investigated to fabricate large-area PSCs [147,148]. Some of these processes can enable PSCs being produced at large scale while achieving high throughput, high costperformance, and high reproducibility [149][150][151][152]. The most recent attempt of producing large area PV modules based on perovskite achieved an aperture area 802 cm² with a PCE of 16.09% [153].…”

Rosario Vidal supported me. I consider the determined confidence she deposited on me as fundamental. I also appreciate she cared about me as one of her doctoral children. I would also like to thank her for assuming that chief tutoring role. Some months later Iván Mora joined us as a co-director of the thesis. His contribution have undoubtfully improved the quality of the thesis. Besides, his continuous recommendations of making everything simpler have become everlasting knowledge for me to hold. The task of both of them have eventually been essential for my personal development purposes as a doctoral student.My desire for completing a doctoral degree comes from my experience in a research group called PIMA as a postgraduate. Along with the members of this group I truly discovered what science and a scientist are. This was thanks to people such as Estefanía Sánchez Safont, Luis Cabedo, José Gámez and Jennifer González, among others. I would like to include in this category other scientist with which I collaborated at that time, with my first published article as a result. They are Rosa Mondragón Cazorla, Leonor Hernández and Enrique Juliá. My contact with them has endured along my doctoral period. An especial mention is for Rosa Mondragón Cazorla, whom I acknowledge the interesting conversations in the many days commuting to the University in the train.More people joined the PIMA group, such as Jorge García Cañadas, Braulio Beltran, Fran Romero, Nuno Araújo and Aziz Aldureid, among others. An especial mention is for Adrián Mota Babiloni, whom I want to thank for his encouragement in pursuing the doctoral training and useful recommendations. I appreciate the interesting conversations we had along the lunchtime and for considering me as one member more of their group.Apart from that, I would like to mention the colleagues of the GID research group, where I mostly developed the thesis. Nuria Sánchez-Pantoja developed her doctoral thesis concurrently to me. Others had either undergraduate or postgraduate stays in the group, such as Higinio Martínez, Eva Esteve Recatalà, Javier Sánchez, Ana García, Gemma Tidó and many more. Two Mexican professors visited the group, Claudia Saldaña and Sarah Messina. I acknowledge the good moments spent with them.During my doctoral period I also worked at Instituto de Tecnología Cerámica. I thank them for the good time spent in the spare time in there. In particular, Irina Celades,
