Toward High-Effi ciency Solution-Processed Planar Heterojunction Sb 2 S 3 Sol…

Low-cost hybrid solar cells have made tremendous steps forward during the past decade owing to the implementation of extremely thin inorganic coatings as absorber layers, typically in combination with organic hole transporters. Using only extremely thin fi lms of these absorbers reduces the requirement of single crystalline high-quality materials and paves the way for low-cost solution processi…
