<p>A solar cell (100, 200, 300) includes multiple organic materials (102-104, 202a-202b, 204a-204b, 302a-302b, 304a-304b) (including at least one donor material and at least one acceptor material) and multiple inorganic materials (114a-114b, 116a-116b, 214-216, 314-316). The organic and inorganic materials collectively form multiple hybrid heterojunction structures. Each hybrid heterojunction structure includes at least two organic materials and at least one inorganic material. A first of the inorganic materials could include nanowires and/or nanotubes, and a second of the inorganic materials could include nanoparticles and/or quantum dots. At least some of the nanoparticles or quantum dots could have different sizes, where the different sizes are associated with different absorption bandgaps. Excitons photo-generated in at least one of the organic materials may dissociate into holes and electrons. Also, electrons and holes photo-generated in at least one of the inorganic material may separate. Further, one or more of the inorganic materials may transport at least some of the electrons towards one of multiple electrodes (110-112, 210-212, 310-312).</p> |
