3. Hybrid solar cell - Wikipedia

   en.wikipedia.org/wiki/Hybrid_solar_cell

   Hybrid solar cells mix an organic material with a high electron transport material to form the photoactive layer. [2] The two materials are assembled in a heterojunction-type photoactive layer, which can have greater power conversion efficiency than a single material. [3] One of the materials acts as the photon absorber and exciton donor. The ...

   The motor side of the unit in case Nos. 2 and 3 can be driven directly by an AC power source (typically when in inverter bypass), a 6-step double-conversion motor drive, or a 6-pulse inverter. Case No. 1 uses an integrated flywheel as a short-term energy source instead of batteries to allow time for external, electrically coupled gensets to ...

5. Hybrid power - Wikipedia
