The study also reveals a complex degradation route that is responsible for failures in aged perovskite solar cells. The understanding could help the future development of photovoltaic technologies with industrially relevant longevity.[13][14][importance?]

2021

2023

General

Research about sustainable energy in general or across different types.

Other energy-need reductions

Research and development of (technical) means to substantially or systematically reduce need for energy beyond smart grids, education / educational technology (such as about differential environmental impacts of diets), transportation infrastructure (bicycles and rail transport) and conventional improvements of energy efficiency on the level of the energy system.

2022

Materials and recycling

2020

2021

    International Union for the Conservation of Nature (IUCN). However, the effectiveness of the moratorium may be questionable as no enforcement mechanisms have been set up, planned or specified.[171] Researchers have outlined why there is a need to avoid mining the deep sea.[172][173][174][175][176]

2022
2023
2024
