Single Junction Highly Efficient Perovskite Solar Cells With Sun-Light Tracking System

Abstract

Perovskite materials as the sunlight-receiving layer in photovoltaic devices have resulted in high short circuit current density (Jsc) along with almost 15% energy conversion efficiency (ECE). The charge transportation layer, absorption layer materials, and their thickness have an important influence on device funtioning parameters. Here, a single layer photons absorbing perovskite material CH ₃ NH ₃ PI ₃ is used which bandgap is 1. 55eV along with a solitary axis sun-light tracking function is integrated. In this investigation, the rays of the sun are utilized by photovoltaic-panels most effectively as a solar tracking mechanism adjusts the photovoltaic-panels to the direction where sun-light beat down vertical on the earth. The device's efficiency has been improved by using an Electron Transport Layer (ETL) of aluminum-doped Zinc Oxide (AZO) and a Hole Transport Layer (HTL) of NiO. A systematic study is conducted in order to provide a comprehensive recommendation for single-junction highly effective perovskite solar cells with their optical properties integrated into sun-tracking devices. So, the solar panel can absorb energy to a maximum extent in a cost-efficient way.
