1. Introduction. Solar photovoltaics (PV) are among the few low-carbon energy technologies capable of satisfying global electricity demand. Today''s leading crystalline silicon (c-Si) and thin-film PV modules are low-cost, efficient, and reliable—but also rigid and heavy, up to 30 kg for a 300 W module.
Colloidal Iron Pyrite (FeS2) Nanocrystal Inks for Thin-Film Photovoltaics
Iron pyrite (FeS2) is a promising earth-abundant semiconductor for thin-film solar cells. In this work, phase-pure, single-crystalline, and well-dispersed colloidal FeS2 nanocrystals (NCs) were synthesized in high yield by a simple hot-injection route in octadecylamine and then were subjected to partial ligand exchange with octadecylxanthate to yield stable …

18 Times More Power: MIT Researchers Have Developed Ultrathin ...
This article is very misleading. Solar is measured in power/area, not power/weight. Telling us the power/weight ratio merely tells us that these cells can be produced cheaply. 18 times more power per kg, but weighing 100 times less, means that if I have 2 solar panels with the same surface area, the one made from the new material will …
