Evaluating the impact of grain boundaries on the functional properties of CdTe thin films, consistent with processes used in photovoltaic solar cells, requires a direct correlation between their crystallography and electronic behavior. In the present

Cu is a well known cause for degradation of CdTe solar cells yet the exact mechanisms remain subject of discussion. We have chosen a novel approach to study CdTe solar cell stability by preparing CdTe solar cells in substrate configuration and applyi

Absorbers for planar perovskite solar cells are often prepared by two-step deposition methods, where a thick compact PbI2 layer is deposited followed by conversion to perovskite using CH3NH3I solution. The surface of the precursor layer quickly react

A selective near-infrared absorbing heptamethine cyanine dye (Cy7-P) electron donor was used for the fabrication of bilayer solar cells with the acceptor C60. Using a reflective metal top electrode, solar cell optimization resulted in an external pow

During processing of CdTe solar cells, sodium can diffuse from the glass substrate into the active layers and can considerably affect CdTe solar cell properties. In this paper, the effects of sodium on structural and photovoltaic properties of low te

The ability to grow efficient CdTe/CdS solar cells in substrate configuration would not only allow for the use of non-transparent and flexible substrates but also enable a better control of junction formation. Yet, the problems of barrier formation a

Solar cells based on polycrystalline Cu(In,Ga)Se(2) absorber layers have yielded the highest conversion efficiency among all thin-film technologies, and the use of flexible polymer films as substrates offers several advantages in lowering manufacturi

Solution processing of Cu2ZnSn(S,Se)4 (CZTSSe)-kesterite solar cells is attractive because of easy manufacturing using readily available metal salts. The solution-processed CZTSSe absorbers, however, often suffer from poor morphology with a bilayer s

Concepts of localized contacts and junctions through surface passivation layers are already advantageously applied in Si wafer-based photovoltaic technologies. For Cu(In,Ga)Se2 thin film solar cells, such concepts are generally not applied, especiall
