Crack Extension in Glass by Laser Irradiation along Laser Scribed Line

Journal of the Japan Society for Precision Engineering, 2008
A mechanical breaking process after laser scribing is indispensable to complete the separation of glass substrate since the crack depth induced by the laser scribing is limited. Laser irradiation along the laser scribed line is introduced in this paper as a crack extension method in depth direction after the laser scribing of a relatively thick glass ...

Progress Toward Efficient Wide‐Gap Cu(In,Ga)(S,Se)2 Thin‐Film Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
Wide‐gap Cu (In,Ga)(S,Se)2 thin‐film solar cells are studied in view of their performance, limitations, and opportunities for further optimization. Different sources of open circuit voltage limitations were discussed and weighted. Interface recombination appears the main recombination channel, which however can be influenced heavy alkali treatment ...

Comparison on Module Performance and Degradation Robustness of Two‐, Three‐, and Four‐Terminal Perovskite Silicon Configurations Under Realistic Operating Conditions

Progress in Photovoltaics: Research and Applications, EarlyView.
We compare the module performance of two‐terminal, three‐terminal, and four‐terminal perovskite/silicon modules in terms mismatch, thermalization, and interconnection losses. For each configuration, the bandgap energy of the perovskite layer is optimized for different locations.

Silver‐Alloyed Wide‐Bandgap (Ag,Cu)(In,Ga)S2 Thin‐Film Solar Cells With 15.5% Efficiency

Progress in Photovoltaics: Research and Applications, EarlyView.
This study reports improvements in compositional homogeneity, microstructure, enhanced radiative recombination, and extended carrier lifetime of CIGS absorber via Ag incorporation. The optimal Ag‐alloyed CIGS solar cells achieve 15.5% PCE and 948 mV VOC, competing with the VOC of the Ag‐free reference sample from the same batch.
