In the chapter of the scientific book the potential of light trapping in tandem micromorph thin-film silicon solar cells is studied by means of optical simulations. The effects of different light trapping concepts on quantum efficiency short-circuit current density and the reductions in absorber layer thickness of top (amorphous) and bottom (microcrystalline) solar cell are analysed.

Study of monolithic contacts and electrical losses in large-area thin-film PV modules has been done on polycrystalline thin-film CIGS modules. Electrical losses have been identified and quantified. Effect of distributed series resistance in the front and back contact together with effect of monolithic contact between adjacent cells. For detailed analysis of electrical losses an electrical model has been developed and it was built-up in PSPICE programe. Developed model offers powerful and easy determination and quantification of losses in PV modules.

Self-built computer-automated measurement set-up for noise characterisation has been used for noise characterisation of amorphous silicon pin diodes. For accurate noise characterisation the detailed noise fingerprint of the measurement set-up has been determined first, since it may significantly contribute to the measurement result.

The influence of the iodine concentration and appropriateness of using binary ionic liquid mixtures in the electrolyte on the solar cell efficiency has been evaluated in order to optimise the electrolyte composition. In parallel the influence of cell temperature and light intensity on the solar cell performance has been studied. The results showed that diffusion of tri-iodide and recombination reactions can be identified as two limiting processes in DSSC. The conversion efficiency of a DSSC resembles the JSC behaviour.

A new procedure has been developed that defines the efficiency versus irradiance and temperature for a specific module, collects the local irradiance and temperature data, and combines the two mathematically, resulting in effective efficiency. The module performance ratio is defined to be the ratio of effective efficiency to that under standard test conditions. A focus on the parameters that control the effective efficiency should provide a path to PV modules with improved field performance.
