Efficiency of Emerging Photovoltaic Devices under Indoor Conditions

Abstract

Emerging photovoltaic (PV) technologies are considered to be excellent candidates to be used as power sources for indoor and low‐light applications. The already demonstrated high power conversion efficiencies (PCEs) and the potential to manufacture perovskite, organic, or dye‐sensitized solar cells at low cost make them particularly interesting. In this work, the maximum PCE of PV devices under low‐light conditions is explored. The role of spectral mismatch, non‐radiative recombination, and parasitic Ohmic losses is investigated. The performed calculation provides guidelines to improve the low‐light performance of PV devices for ambient light. In addition, a simple measurement procedure for the indoor PCE is discussed.

Impact of PCBM as a Third Component on Optical and Electrical Properties in Ternary Organic Blends

“…The sun is the most significant and cleanest energy resource since it is a limitless source of free fuel that has the enormous potential to supply much more energy than the planet needs. Nevertheless, there are certain restrictions on how photovoltaic devices (solar cells) can absorb solar energy and convert it into electricity [5]. The most crucial requirements for solar cells are a high photon-to-electron conversion efficiency and affordable production costs, adding to these the lifetime, stability, availability, and performance of the materials on which they are based [6].…”
