Abstract

Perovskite solar cells (PSCs) 1-6 have received tremendous attention during past decade by showing numerous possibilities such as facile fabrication processes or achieving impressive solar-to-electrical conversion efficiencies, which has now crossed over 25% for lab-sized devices 7.

The purpose of this course is to provide an opportunity to the doctoral students to get familiarized regarding this emerging photovoltaic technology. The course will be comprised of 1-4 lectures from the prominent scholars of the field, which will provide theoretical background, operating principles and device characterization techniques to the doctoral students. After that, the course will be further supported with 1-3 days of intense laboratory course to give these doctoral students hands-on training for making laboratory-sized (nearly 1 cm2) PSCs.

At the same time, the students will also receive hands on training for PSCs characterizations techniques such as J-V curve measurement of the PSCs under full sun light of an artificial solar simulator, incident photon to collected electron efficiency (IPCE) measurements, X-rays diffraction (XRD) measurements or FTIR measurements (Figure 2).

Figure 2: The students will get hands on experience for the numerous characterization techniques such a) J-V curve measurements to determine the solar-to-electrical energy conversion 6 b) the incident photon to collected electron efficiency (IPCE) measurements 5 c)  X-rays diffraction (XRD) measurements 6 or d) FTIR measurement 6 in order to acquire knowledge regarding the characteristics of the fabricated PSCs.

The students (10-15 doctoral students are expected to join the course) will be divided into 3-4 groups who will be given tasks to prepare the PSCs characterization reports at the end of the laboratory training. As a result, intense knowledge gain, interest building along with improvements in scientific skills (both in terms of experimental know how and scientific writing) is highly expected, which can trigger many doctoral students for pursuing towards scientific challenges associated to make PSCs as commercial hit. In this regard the doctoral students from multidisciplinary backgrounds such as chemistry, physics, materials science or nanotechnology are expected, among them, some of these doctoral students could also pursue to continue their research in the field of PSCs as post-doctoral researchers.

We have invited prominent scholars will who be delivering lectures discussing striking characteristics and opportunities around this emerging photovoltaic technology and perovskites based materials for future applications.
