Photovoltaic (PV) energy conversion of sunlight into electricity is now a well-established
technology and a strong further expansion of PV will be seen in the future to answer the …

Abstract Cu (In, Ga) Se 2 (CIGS) based solar cells including an ultra-thin absorber layer (<
500 nm) allow cost reduction but lack of sufficient generation of current. A solution would be …

In the past three years, record efficiency of Cu (In, Ga) Se2 (CIGS) based solar cells has
improved from 20% up to 22.6%. These results show that CIGS absorber is ideal for thin-film …

A new photovoltaic (PV) device current mapping method has been developed, combining
the recently introduced compressed sensing (CS) sampling theory with light beam induced …

Solar cell characterization is carried out by current-voltage (IV) and spectral response
measurements. These characteristics of the solar cell depend on solar cell design …

In this letter, we investigate the origin of the spatial inhomogeneity of the photoluminescence
(PL) intensity maps obtained on thin-film solar cells. Based on a hyperspectral imager setup …

Lead sulphide (PbS) thin film have been deposited onto zinc plate by electrodeposition
technique. The electrical (I/V) characterization was carried out using four point probe were …

Reducing the absorber thickness of thin-film photovoltaic devices is a promising way to
improve their industrial competitiveness, thanks to a lower material usage and an increased …

Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-
film transistors in LCDs. Used as semiconductor material for a-Si solar cells, or thin-film …

This thesis deals with the multi-transition solar cells by studying two subband gap localised
states materials: one highly mismatched alloy, GaAsPN, and one multi-stacked quantum …
