Photoelectrochemical cells employing organic semiconductors (OS) are promising for solar-to-fuel conversion via water splitting. However, despite encouraging advances with the half reactions, complete overall splitting remains a challenge. Herein, robust photocathode operating in near-neutral pH electrolyte by careful selections of semiconducting polymer bulk heterojunction (BHJ) blend and char...

Tandem solar cells have a superb potential to push the power conversion efficiency (PCE) of photovoltaic technologies. They can be also more stable and economical. In this simulation work, an efficient perovskite cell (PSC) with Spiro-OMeTAD as hole transport material (HTM) no electron (ETM) replace traditional PSC structure is presented. This then used top sub together copper indium gallium su...

Multi-junction solar cells provide the highest efficiencies. Intense research activity is being held with aim to increase actual performance reached by these cells. Harvesting most of spectrum and finding optimum design variables in terms structural parameters carrier concentrations are main topics investigated developers. The GaAs/GaSb based dualjunction cell was found suitable for best absorp...
