“…Items of INT and EVA were measured using an ad hoc scale of measurement. This method includes “respondents in framing the questionnaire items associated with their knowledge and involvement regarding the particular phenomenon” (Masuda and Hara, 2017, p. 183). For developing the scale items of an ad hoc questionnaire, a three-step approach was followed.…”

PurposeThis study identifies the facilitators and inhibitors for the adoption of e-learning for the undergraduate students of architecture. Nine constructs are identified as facilitators and five constructs are identified as inhibitors to the adoption of online learning systems in the context of the study. These constructs were used to propose a research model.Design/methodology/approach596 architecture undergraduates responded to a structured questionnaire. The questionnaire was finalized after a pilot study and included standard scale items drawn from previous studies. An exploratory factor analysis was followed by structural equation modeling (SEM) to test the proposed model.FindingsAll the identified facilitators emerged significant except social influence and price value. Furthermore, technology risk emerged insignificant while all other inhibitors had significant impact on Behavioral Intention to adopt e-learning.Research limitations/implicationsThe study has strong implications in academia as HEIs in developing countries need to make their students computer proficient, boost the implications of e-learning services by mitigating risks and motivating students to acquire knowledge through flexible e-learning modules.Originality/valueThe COVID-19 pandemic forced educational institutions to switch to online modes of learning. For students of architectural programs in a developing country like India, this has been unprecedented and has brought in a new set of challenges and opportunities. With the extension of the pandemic induced lockdown in educational institutions, students – and other stakeholders – have no choice but to adapt to this new normal of dependence on remote learning.

The study develops a theoretical framework that highlights facets of perceived risk and their relationship with behavioural intention. Previous literature highlights that the higher the risk perceived by doctors, the more prospects that they will not adopt telemedicine. Therefore, addressing these risks will help doctors to overcome their apprehensions about telemedicine. The data were collected through field as well as an online survey. An online survey link was shared with doctors of various hospitals in North India. The final sample consisted of 215 observations. Structural equation modelling (SEM) was applied to validate the hypothesized relationships among constructs. The results confirmed that social risk, time risk, technology risk and security risk had a negative impact on behavioural intention. Surprisingly, financial risk emerged as an insignificant construct. This study contributes to literature by presenting and validating a theory-driven framework that unveils the facets of perceived risk as barriers to telemedicine adoption.

“…However, several studies have clarified that illumination during PID stress slows the degradation rate. [ 62–65 ] These findings indicate that sunlight plays an important role in shunting‐type PID.…”

“…Luo et al [ 24 ] speculated that solar cell sensitivity to polarization‐type PID is related to the passivation/antireflection structure. We derive a plausible hypothesis from results of studies of the effect of illumination on shunting‐type PID [ 62–65 ] and from cell‐level preventive measures against polarization‐type PID. [ 26,29 ] In shunting‐type PID, the delay of PID in the presence of illumination is explained as follows.…”

n‐Type crystalline‐silicon (c‐Si) photovoltaic (PV) cell modules attract attention because of their potential for achieving high efficiencies. The market share of n‐type c‐Si PV modules is expected to increase considerably, with wide use in PV systems, including large‐scale PV systems, for which the system bias is set as markedly high. Such a high system bias leads to performance losses known as potential‐induced degradation (PID). By virtue of many researchers’ efforts, the PID behaviors, mechanisms, and preventive measures against PID have been well documented in conventional p‐type c‐Si modules. Researchers recently started to investigate PID in high‐efficiency c‐Si solar cells including n‐type c‐Si PV modules. Yet, the understanding of PID phenomena remains incomplete. Herein, a literature review of PID in high‐efficiency n‐type c‐Si PV modules is provided as a resource elucidating the current status of related research and remaining unresolved issues. This report mainly presents discussion of PID in several kinds of n‐type c‐Si PV modules in terms of materials science. PID phenomena are described as divided into some degradation modes. Details present a review of their respective degradation modes, degradation behaviors, proposed mechanisms, and potential measures against degradation. Remaining open issues and anticipated future studies are also summarized.
