TANDEM TYPE SOLAR CELL COMPRISING ORGANIC PHOTOELECTRIC CONVERSTION MATERIAL

摘要

PURPOSE: A tandem type solar cell including organic photoelectric conversion materials is provided to improve photoelectric conversion efficiency by reducing a refractive index between a first substrate and a second substrate through a transmissive combination unit including a pressure sensitive adhesive film. CONSTITUTION: A first photoelectric conversion unit(200) includes a first electrode unit(210), a first photoelectric conversion layer(230), and a second electrode unit(250). A second photoelectric conversion unit(300) includes a third electrode unit(310), a second photoelectric conversion layer(330), and a fourth electrode unit(350). The first photoelectric conversion unit and the second photoelectric conversion unit are located on both sides of a substrate unit(100). The substrate unit includes a first substrate and a second substrate.
