WORKING PRINCIPLES OF PEROVSKITE SOLAR CELLS

Environmental assessment of perovskite solar cells

It is a well-known fact that PSCs tend to decompose after being exposed to external factors such as heat, light, humidity, and oxygen, which is mostly a result of the intrinsic structural instability of absorber layers . For example, Niu et al. have probed the decomposition behavior of methyl lead ammonium iodide. . During the operation of solar cells under the sunlight, their temperature can go beyond 45 °C. For PSCs to be true competitor with silicon-based solar cells, long-term stability at 85 °C. . The effect of temperatures on the morphologies of the perovskite layer is essential to assess device performance in different environmental conditions. For example, the work of. . A systematic study by Foley et al. have illustrated that valence band maximum and conduction band minimum of CH3NH3PbI3 shifted. . In high-efficiency PSCs, gold (Au) and silver (Ag) are the most commonly used electrodes. Despite high costs, both show degradation as a result of. [pdf]

FAQS about Environmental assessment of perovskite solar cells

Aligned with UN SDG 7 for affordable and clean energy, it promotes renewable development for a more sustainable PV technology for the future. 1. Introduction

Are perovskite-based Tandem solar cells competitive in the LCOE?

Li et al. conducted a detailed cost analysis of two types of perovskite-based tandem modules (perovskite/Si and perovskite/perovskite tandems) with standard c-Si solar cells and single-junction perovskite solar cells. They found that if the lifetime of the module is comparable to that of c-Si solar cells, tandem cells were competitive in the LCOE.

Are perovskite tandems scalable?

Previous life cycle assessment (LCA) studies on perovskite tandems investigated specific tandem stacks, but only considered limited impact categories (8, 21 – 23) because of the incomplete high-quality life cycle inventory (LCI) datasets in existing databases, and do not consider scalability and industry-compatibility issues.
