ABSTRACT
Renewable energy conversion using photovoltaic devices plays a crucial role in converting solar energy into electricity. Improving the efficiency and lifetime of the photovoltaic (PV) cell is one of the intense research activities solving the problem of energy issues and environmental concerns. Carbon-based photovoltaic cells exhibit numerous advantages and efficiency 2improvements over ordinary photovoltaic cells. Material properties like high surface area, low cost, and high electrical conductivity play a key role in efficiency improvement. Energy generation using carbon-based photovoltaic materials in the future is an alternating, safe, low-cost, and efficient method. Structures like carbon nanotube (CNT), fullerene, graphene, etc., have a wide range of applications like photoanode, cathode in DSSC, electron transport layer (ETL), hole transport layer (HTL), and encapsulant in photovoltaic (PV) cells. The applications of carbon-based nanomaterials devices like photovoltaics in energy generation applications are discussed in this chapter.
