- Abstract
- Nanowires provide interesting features for photovoltaic applications. Materials with desirable band gaps can be combined into heterostructures with very little strain and with a fraction of the material consumption seen in conventional solar devices. Moreover, nanowires show outstanding optical absorption and InP and GaAs nanowire solar cells have been shown to reach efficiencies of 13.8 % and 15.3 %. This project has been done as a step towards building tandem solar cell structures with a top cell consisting of nanowires. A method in which arrays of nanowires with lengths around 2 m can be peeled off from their native substrate when embedded in a polymer while keeping their array structure and their vertical orientation has been...

A method in which arrays of nanowires with lengths around 2 m can be peeled off from their native substrate when embedded in a polymer while keeping their array structure and their vertical orientation has been investigated. Moreover, nanowire gold tips were successfully localized using a conductive AFM and imaging of pin-doped InP- nanowires with this
method was performed. (Less) - Popular Abstract (Swedish)
- Med hjälp av nanotrådar kan vi effektivisera solceller och minska åtgången av dyra och sällsynta material. Detta projekt har genomförts som ett led i att utveckla en metod där vertikala nanotrådar som var och en innehåller en solcell överförs till en plan solcell för att bygga så kallade tandemsolceller med förbättrad effektivitet.
