“…However, for converting solar energy into electricity we need low-cost and highly efficient solar cells. [10] This is one of the reasons of achieving high PCE in PSCs in comparison with that in OSCs where the exciton binding energy is larger and excitons cannot be dissociated without any excess energy available which leads energy loss and hence less PCE. Solar cells based on hybrid halide perovskites of the structure AMX3, where A is an organic cation, M is a metal cation, and X is a halide anion, have achieved a power conversion efficiency (PCE) higher than 22 %.…”

“…Perovskite solar cells (PSCs), being highly efficient and cost effective, [2,3] have great potential to meet the increasing domestic and industrial energy demands. [10][11][12][13] In the past few years, it is noted through the study of charge transport dynamics that the diffusion length of charge carriers in the PSCs plays a significant role in their performance. [4,5] High PCE in PSCs may be attributed to the high absorption coefficient, high carrier mobilities, and long charge carrier diffusion lengths.…”

The diffusion length of charge carriers in the active layer of a perovskite solar cell (PSC) of the structure Glass/PEDOT: PSS/ CH 3 NH 3 PbI 3 /PC60BM/Al is modelled. It is found that the diffusion length depends on the position x in the active layer measured from the PEDOT: PSS interface, Urbach energy and temperature. By varying the voltage in the range from zero to V oc , it is shown that the dependence of diffusion length on the position x in the active layer reduces at higher voltage. The combined influence of applied voltage and temperature on the diffusion length of charge carriers is investigated and it is found that in the low voltage range the diffusion length is temper-ature independent, but it becomes significantly temperature dependent at higher voltages. Also, it is found that the diffusion length decreases as the applied voltage increases and this reduction becomes much more significant at higher voltage and temperatures. The combined influence of applied voltage and Urbach energy on diffusion length of charge carriers reveals that the diffusion length decreases when both the applied voltage and Urbach energy increase. However, the reduction in the diffusion length due to the increase in Urbach energy becomes less significant at higher voltage.

This paper discusses the results for heterojunction solar cells based on three components (with fullerene acceptor), which are based on the pyrazoloquinoline derivative. Photovoltaic devices based on ternary systems are presented along with a model optimization for such mixtures. The device bulk-heterojunction type cells represent architecture ITO/PEDOT:PSS/ organic active layer/aluminum in various configurations of the active layers. The authors have analyzed the current-voltage characteristics of photovoltaic cells and determined the parameters.

Two‐dimensional (2D) materials have attained widespread research interest in renewable energy generation and storage applications. The 2D materials hold the potential to overcome limitations in the classic renewable energy harvesting technology and are expected to revolutionize the standard materials with magnificent performance and low production cost in the future era of renewable energy. In this article, we review certain novel 2D materials for renewable energy devices with a special focus on electrochemical‐based hydrogen generation approaches as green, clean, and zero‐carbon fuels. Besides, the article covers the atmospheric CO 2 reduction approach for the synthesis of hydrocarbon fuels and conversion of H 2 into ammonia through N 2 reduction using 2D material–based photo/electrocatalytic pathways.
