Device Performance of Emerging Photovoltaic Materials (Version 4)

Following the 3rd release of the "Emerging PV reports", the best achievements in the performance of emerging photovoltaic (e-PV) devices in diverse e-PV research subjects are summarized, as reported in peer-reviewed articles in academic journals since August 2022. Updated graphs, tables, and analyses are provided with several performance parameters, such as power conversion efficiency, open-circuit voltage, short-circuit current density, fill factor, light utilization efficiency, and stability test energy yield. These parameters are presented as a function of the photovoltaic bandgap energy and the average visible transmittance for each technology and application, and are put into perspective using, for example, the detailed balance efficiency limit. The 4th installment of the "Emerging PV reports" discusses the "PV emergence" classification with respect to the "PV technology generations" and "PV research waves" and highlights the latest device performance progress in multijunction and flexible photovoltaics. Additionally, Dale-Scarpulla's plots of efficiency-effort in terms of cumulative academic publication count are also introduced.|The power conversion efficiency (PCE) as a function of the photovoltaic bandgap energy (Eg) is shown as summarized by the yearly emerging PV reports (e-PVr) published in Advance Energy Materials over the last 4 years, as well as in the website and database.image
