Abstract
Embodiments relate to a light-harvesting perovskite layer including having deoxyribonucleic acid (DNA) molecules incorporated within the perovskite crystal to serve as an effective carrier transport medium. Some embodiments include formation of a DNA doped MAPbI3, the DNA doped MAPbI3 being formed by using a DNA-hexadecyl trimethyl ammonium chloride (“DNA-CTMA”) complex. The DNA doped MAPbI3 can be used as the light-harvesting perovskite layer in a photovoltaic device. Other molecules such as artemisinin (ART) and melanin are also demonstrated to show the effectiveness in charge and thermal transport.
