Title:
ELECTRONIC DEVICE COMPRISING SOLAR CELLS OF MULTIPLE TYPES
Document Type and Number:
WIPO Patent Application WO/2020/022705
Kind Code:
A1
Abstract:
According to various embodiments, an electronic device comprises: a polymer including a plurality of quantum dots; at least one first solar cell disposed on a lower portion of the polymer; and at least one second solar cell disposed on a side portion of the polymer; and a battery configured to be charged with electrical energy from at least one of the first solar battery or the second solar battery, wherein: the first solar battery, in a first wavelength band, has a conversion efficiency greater than or equal to a critical value; the second solar battery, in a second wavelength band different from the first wavelength band, has a conversion efficiency greater than or equal to the critical value; and the wavelength of light that passes through the polymer may be within the first wavelength band, and the wavelength of light that is absorbed by at least some of the plurality of quantum dots and then remitted may be within the second wavelength bandwidth. Other various embodiments are possible.
