Fundamental Mechanisms Behind the Reverse Characteristic of Cu(In,Ga)Se2 Solar Cells

Partial shading of PV modules can lead to degradation of the shaded cells. The degradation originates from a reverse bias voltage over the shaded cells. In order to mitigate reverse bias damage in Cu(In,Ga)Se2 (CIGS) modules, a good understanding of the fundamental mechanisms governing the reverse characteristic is required. In this study, a...

Optimized grid design for thin film solar panels

There is a gap in efficiency between record thin film cells and mass produced thin film solar panels. In this paper we quantify the effect of monolithic integration on power output for various configurations by modeling and present metallization as a way to improve efficiency of solar panels. Grid design and finger dimension optimization was...

Improvement of transparent conducting materials by metallic grids on transparent conductive oxides

The trade-off between transparency and conductivity in transparent conductors used in optoelectronic devices is a major bottleneck towards higher device performances. Grid deposition on transparent conductive oxides was demonstrated using electrochemical deposition, which has the advantage of a high aspect ratio of 0.45 and the possibility to...
