Optical Analysis of Perovskite/Silicon Tandem Solar Cells: Effect of Rear Side Grating and TOPCon Tunnel Junction

open access: yesSiliconPV Conference Proceedings
In the focus of the presented work is the analysis of a rear side reflection grating in context of a perovskite/silicon tandem solar cell. The typical configuration of a perovskite/Si tandem device requires a hole transport layer at the rear side of the

A Novel Universal Solar Energy Predictor [PDF]

open access: yesarXiv, 2019
Solar energy is one of the most economical and clean sustainable energy sources on the planet. However, the solar energy throughput is highly unpredictable due to its dependency on a plethora of conditions including weather, seasons, and other ecological/environmental conditions.

Fibrous Pb(II)‐Based Coordination Polymer Operable as a Photocatalyst and Electrocatalyst for High‐Rate, Selective CO2‐to‐Formate Conversion

open access: yesAdvanced Functional Materials, EarlyView.
A coordination polymer [Pb(tadt)]n prepared by a microwave‐assisted solvothermal method selectively reduces CO2 into formate under visible light with a high apparent quantum yield of ≈25% at 400 nm. It can function as a pre‐catalyst, along with conductive Ketjen Black, to form an active PbCO3/Pb3(CO3)2(OH)2 mixture that exhibits a high Faradaic ...

An Iron-Rich Sun and Its Source of Energy [PDF]

open access: yesarXiv, 2004
Mass-fractionation enriches light elements and the lighter isotopes of each element at the solar surface, making a photosphere that is 91 percent H and 9 percent He. The solar interior consists mostly of elements that comprise 99 percent of ordinary meteorites (Fe, O, Ni, Si, S, Mg and Ca) elements made in the deep interior of a supernova. Solar energy

Selective Reduction Laser Sintering: A New Strategy for NO2 Gas Detection Based on In2O3 Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
This research utilizes selective reduction laser sintering (SRLS) to engineer In2O3 NPs for flexible NO2 sensors. The introduction of oxygen vacancy defects enhances sensor performance, offering excellent responsiveness, rapid response/recovery, superior selectivity, low detection limit, and long‐term stability.
