    Abstract: The design, development and improvtableement in electronic devices and components have led to the further miniaturization of the system devices and their interconnecting interfaces. Hence, reducing the size of the transmitter (Tx) chips, receiver (Rx) chips and associated components play an important role in designing a reduced/small sized optoelec... Show More

    Abstract: Hybrid organic-inorganic perovskite solar cells have attracted the attention of researchers and scientists throughout the world. From 2009, when actual research work began on photovoltaic perovskite applications, a lab power conversion efficiency above 23.3% have been achieved. Whereas, silicon solar cells have only achieved power conversion effici... Show More
