1. Optical spectroscopy of InGaAs quantum dots
Sammanfattning : The work presented in this thesis deals with optical studies of semiconductor quantum dots (QDs) in the InGaAs material system. It is shown that for self-assembled InAs QDs, the interaction with the surrounding GaAs barrier and the InAs wetting layer (WL) in particular, has a very large impact on their optical properties.

2. Hole Transport Materials for Solid-State Mesoscopic Solar Cells
Sammanfattning : The solid-state mesoscopic solar cells (sMSCs) have been developed as a promising alternative technology to the conventional photovoltaics. However, the device performance suffers from the low hole-mobilities and the incomplete pore filling of the hole transport materials (HTMs) into the mesoporous electrodes. LÄS MER
3. Organic Hole-Transport Materials for Perovskite Solar Cells
Sammanfattning : Research on perovskite solar cells (PSCs) has undergone dramatic development since the first cells were reported in 2009, and the past decade has witnessed a significant breakthrough on their power conversion efficiencies (PCEs) from 3.8% to 25%. LÄS MER
4. A molecular guide to efficient charge transport : Coordination materials for photovoltaic cells
Sammanfattning : Emerging solar energy conversion and energy storage technologies play a vital role in solving the present energy crisis and achieving carbon net zero. Currently, they are limited by the use of inefficient, unstable and expensive charge transport materials. LÄS MER
5. Novel organic sensitizers and hole transport materials for efficient solid-state photovoltaic devices
Sammanfattning : State-of-art solid-state photovoltaic devices, such as solid-state dye sensitized solar cells (ssDSSCs) and perovskite solar cells have attracted significant attention due to their high efficiency and potential low-cost manufacture. However, there are still challenges that limit the application up-scaling.. LÄS MER
