  1. 21. Recycling end-of-life silicon PV panel with molten salt bath

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Liying Yu; [2023]
    Keywords : ;

    Abstract : Solar energy is recognized as a clean way to produce electricity. Solar PV's installed capacity is increasing in recent years. However, a PV panel has a 25-year lifespan on average. In actuality, 95% of the mass of PV components can be recycled. READ MORE

  3. 22. Scalable Reinforcement Learning for Formation Control with Collision Avoidance : Localized policy gradient algorithm with continuous state and action space

    University essay from KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Andreu Matoses Gimenez; [2023]
    Keywords : Control theory; Multi-agent systems; Distributed systems; Formation control; Collision avoidance; Reinforcement learning; Teoria de control; Sistemes multiagent; Sistemes distribuïts; Control de formació; Prevenció de col·lisions; Reinforcement Learning; Reglerteknik; Multi-agent system; Distribuerade system; formationskontroll; Kollisionsundvikande; Reinforcement learning; Teoría de control; Sistemas multiagente; Sistemas distribuidos; Control de formación; Prevención de colisiones; Reinforcement Learning;

    Abstract : In the last decades, significant theoretical advances have been made on the field of distributed mulit-agent control theory. One of the most common systems that can be modelled as multi-agent systems are the so called formation control problems, in which a network of mobile agents is controlled to move towards a desired final formation.

    Abstract : In recent years, there has been a huge increase in the use of satellite communications. This has led to a need for more capacity, which can be solved by moving towards higher frequency bands in search of higher bandwidths. READ MORE

  5. 24. Thin Indium Tin Oxide Layer Development for Crystalline Silicon/Perovskite Two Terminal Tandem Solar Cell

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Aravind Srinivasachari; [2023]
    Keywords : Indium Tin Oxide; Thin-film characterisation; Magnetron Sputtering; Screen printing; Tandem Solar Cells; Indium-tennoxid; karaktärisering av tunnfilm; magnetronförstoftning; screentryck; tandemsolceller;

    Abstract : ITO is widely regarded as the optimal TCO for serving as front window layer in PSK/c-Si tandem solar cells. It is known to effectively mitigate several stability issues present in perovskite solar cells while demonstrating excellent lateral conductivities and optical transparency across the entire solar spectrum.

  6. 25. Energy audit : An analysis of the energy audit process at the company Sustainable Intelligence

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Ida Rosing; [2023]
    Keywords : Energy audits process; Energy mapping process; Case study Analyze;

    Abstract : As energy prices increase and the effect of global warming hits the world harder, the need of reducing our energy use, and by that decreasing our environmental footprint increases. According to the International Energy Agency the energy consumption hit a new record in 2019 with 419 EJ, corresponding to 36,6 Gt of carbon dioxide emissions. READ MORE
