Abstract: In this thesis, coupling organic thermoelectrics (TE) with organic solar cells (OSCs) is explored as an approach to solid-state solar harvesting. Firstly, we demonstrate the ability of organic TE materials to absorb solar radiation and convert it into electricity via a two-step process. Secondly, we investigate three different device geometries to couple an OSC to a thermoelectric generator (TEG), drawing upon experimental data from FTIR spectroscopy and IR thermography. Thirdly, we investigated the effect of temperature on OSC device performance via light-intensity- and temperature-dependent J-V characteristics, observing a reversible enhancement in device performance for some systems arising as a result of thermally-activated charge transport in the device.
