Hole transport matertial (HTM) as charge selective layer in perovskite solar cells (PSCs) plays an important role in achieving high power conversion efficiency (PCE). It is known that the dopants and additives are necessary in the HTM in order to improve the hole conductivity of the HTM as well as to obtain high efficiency in PSCs, but the additives can potentially induce device instability and poor device reproducibility.

14 p, 2.8 MB Socio-technical discourses of European electricity decarbonization : contesting narrative credibility and legitimacy with quantitative story-telling / Renner, Ansel (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Giampietro, Mario (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
This paper presents an innovative approach to the responsible use of quantitative analysis when dealing with the governance of sustainability. Rather than using complicated models which try to predict and control the future evolution of complex adaptive systems, quantitative story-telling is proposed to check, first of all, the plausibility of proposed policies.
