  2. 16. Lead auditors, their client portfolios and performances

    Author : Amin Salimi Sofla; Stefan Sundgren; Tobias Svanström; Lasse Niemi; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Audit Quality; Client Portfolio; Lead Auditor;

    Abstract : This thesis focuses on lead auditors' differences in terms of client portfolios and performances. First, lead auditors are surveyed and their responses on professional scepticism linked to their performances. Second, survey and archival data are combined to check whether self-control is related to performance. READ MORE

  4. 17. Lead-free Metal Halide based Solar Cells

    Author : Huimin Zhu; Erik Johansson; Gerrit Boschloo; Feng Gao; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Low-toxicity; emerging light harvesters; lead-free; low toxic bismuth; Ag Cs -Bi Sb -I Br systems; 2D perovskites.;

    Abstract : Lead-halide perovskites have recently appeared as very promising materials for solar cells. However, their stability and toxicity may be limiting factors for their application. Therefore, to find new low toxic and high stability light harvesters may be necessary for overcoming the challenges of perovskite solar cells. READ MORE
