Abstract: Instability in perovskite solar cells is the main challenge for the commercialization of this solar technology. Here, a contactless, nondestructive approach is reported to study degradation across perovskite and perovskite/silicon tandem solar cells. The technique employs spectrally and spatially resolved absorptivity at sub‐bandgap wavelengths of perovskite materials, extracted from their luminescence spectra. Parasitic absorption in other layers, carrier diffusion, and photon smearing phenomena are all demonstrated to have negligible effects on the extracted absorptivity. The absorptivity is demonstrated to reflect real degradation in the perovskite film and is much more robust and sensitive than its luminescence spectral peak position, representing its optical bandgap, and intensity. The technique is applied to study various common factors which induce and accelerate degradation in perovskite solar cells including air and heat exposure and light soaking. Finally, the technique is employed to extract the in idual absorptivity component from the perovskite layer in a monolithic perovskite/silicon tandem structure. The results demonstrate the value of this approach for monitoring degradation mechanisms in perovskite and perovskite/silicon tandem cells at early stages of degradation and various fabrication stages.

Abstract: This article proposes alternative understandings of certain structuralist informed (Diagnostic and Statistical Manual of Mental Disorders - DSM-IIIrd to 5th Eds.) configurations of mental disorders. Life’s negative discourses and the mind’s captive responses present a “general theory of mental suffering” which phenomena are classified as modernist, DSM mental disorders, such as addictions, depression, and obsessive-compulsive disorders. Recent research has indicated that the psychedelic drug, psilocybin, has produced safe and effective outcomes for these mental suffering states. In this context, the article draws on the concept of brain plasticity order, firstly, to identify the means for a person to move away from subjection of life’s negative, dominant discourses that “capture” the brain, and then to intentionally move towards more acceptable, preferred, ethical subjectivities. These explanations, using the phenomenon of depression, provide the foundation for further proposals that an innovative form of narrative therapy could be a safe, effective and meaningful approach for persons in relationship with other similar ways of mental suffering, such as, anxiety, addiction, obsessive-compulsive disorder, and anorexia nervosa.

Abstract: The purpose of this article is to apply innovative analogue and digital thinking processes that, first, negate DSM (III to 5th Eds.) understandings of anorexia, and then formulate a bases which encapsulates alternative understandings of the universal patterns of behavior, understandings that honour and embrace the patterns of behavior expressed by each person. Published research of lived experiences of persons who exhibit patterns of behavior and attitudes towards food, weight, body shape and size, that are deemed to be diagnostic criteria of anorexia nervosa, provides evidence that those patterns of behavior serve as coping mechanisms against the suffocating forces of unwanted, specific, and personal discourses in their lives. As a consequence of this application, the article argues that these universal patterns of behavior and attitudes to food, weight and body image, expressed uniquely by each person, are expressions, images and ideas of a specific form of an archetype, with each person having their personal and unique reasons for their behavioral expressions. This analyses indicates that these persons do not “suffer from” a mental eating disorder called anorexia, and that psychotherapeutic approaches for each person should focus on the problems in their lives, problems that cause them to express the images and ideas of a universal archetype.

Abstract: In this article are compared the underpinning beliefs, ideas, and practices between Tibetan Buddhist philosophies, with Western understandings about mental suffering in living, and the nature of contextual issues that structure the recovery from such suffering. On the basis of this undertaking, in the study were explored the similarities and relationships of the Buddhist belief that it is possible to end the suffering in life, and then venture on “the path to happiness”, compared with a Western, post-modern narrative informed approach to psychotherapy for persons in relationship with mental suffering. The analysis of the historic and current belief systems has indicated similar philosophical and practical positioned relationships between Tibetan Buddhism’s Four Noble Truths, and current Western understandings of mental suffering, and a narrative informed approach to psychotherapy. These comparative constructs, that span many centuries, should provide supportive insights and considerations to current understanding of causes, and the nature of human responses to living experiences that initiate and maintain mental suffering. In addition, they should also promote confidence for discerning perceptions and support for person’s to deal effectively with phenomena resulting in mental suffering, with a narrative informed approach to psychotherapy.
