Enhancing performance of polar InGaN-based thin film solar cells through intrinsic layer impact optimization: Numerical modeling

The paper deals with the conception and feasibility of the device structure based on the optimized PIN-(In, Ga)N homojunction solar cells. A new and efficient model combining the most realistic ones considering the impacts of band gap narrowing, collection efficiency, Shockley-Read-Hall recombination, and interface polarization is proposed to...

Performance assessment of an eco-friendly tandem solar cell based on double perovskite Cs₂AgBiBr₆

Tandem solar cells have a wider photon absorption range, allowing them to provide better efficiency than single-junction SC. The upper cell absorbs high-energy photons, while the lower cell absorbs low-energy filtered photons. However, in order to obtain affordable, efficient, and long-lasting SC, the absorber layers of the top and bottom...

A Comparative Study of (Cd,Zn)S Buffer Layers for Cu(In,Ga)Se₂ Solar Panels Fabricated by Chemical Bath and Surface Deposition Methods

Scale-up to large-area Cu(In, Ga)Se ₂ (CIGS) solar panels is proving to be much more complicated than expected. Particularly, the non-vacuum wet-chemical buffer layer formation step has remained a challenge and has acted as a bottleneck in industrial implementations for mass-production. This technical note deals with the...
