Self-Passivating hybrid (organic/inorganic) tandem solar cell [PDF]
, 2009 A tandem photovoltaic device structure, consisting of a PbSe nanocrystal film and a P3HT/PCBM bulk heterojunction film, was fabricated. The PbSe film (top layer) serves as a photocurrent generator as well as a UV protector for the underlying polymer cell.

Dry‑Contact Trimming for All‑Perovskite Tandem Solar Cells via Solid‑Solution Homogenization
Advanced Energy Materials, EarlyView.Narrow‐bandgap Sn–Pb perovskites are promising bottom absorbers for all‐perovskite tandems but suffer from Sn‐rich surfaces and depth‐dependent lattice/compositional inhomogeneity. Layered‐perovskite‐assisted dry‐contact trimming removes Sn‐rich surface species and reconfigures the Sn–Pb absorber, enabling efficient charge collection, reduced voltage ...

Advanced Energy Materials, EarlyView.A compact, nonporous, and highly crystalline layered inorganic precursor formed by thermal evaporation inherently restricts its conversion into the halide perovskite phase during vapor‐assisted hybrid two‐step deposition. Introducing localized heterogeneous nucleation sites during vapor deposition enables deliberate modulation of the inorganic layer's ...

Towards Nanowire Tandem Junction Solar Cells on Silicon
IEEE Journal of Photovoltaics, 2018 The development of photovoltaics as a serious means of producing renewable energy has accelerated greatly in the last ten years, with prices for silicon-based solar cell systems dropping dramatically in the last few years. The next great opportunity for photovoltaics following this competitiveness in prices will be to enhance the cell and panel ...

Lattice Coherency‐Driven (111)‐Oriented Wide Bandgap Perovskite Films
Advanced Energy Materials, EarlyView.Methylammonium lead chloride (MAPbCl3)‐derived seed templates regulate wide‐bandgap perovskite crystallization through coupled thermodynamic and kinetic effects. Lattice‐coherent templating lowers the energy cost for (111) epilayer growth, while growth retardation controls crystallization kinetics, ultimately producing highly crystalline face‐up (111 ...
