Lowering Cost Approach for CIGS-Based Solar Cell Through Optimizing Band Gap Profile and Doping of Stacked Active Layers─SCAPS Modeling

In this research article, we carry out investigation on compensating the efficiency loss in thin-film CIGS photovoltaic (PV) cell due to absorber coat depth reduction. We demonstrate that the efficiency loss is mainly caused by the disruption of the charge-carrier transport. We propose an architecture engineered with a stepped band gap profile for improving the efficiency of charge-carrier transport and collection. By modifying the gallium content, we tuned the band gap profile of the active layer of a reference experimental cell from which we previously collected all parameters. Using the simulator environment SCAPS-1D, we modeled a three-steps stacking profile of active layer with different gallium contents from one layer to another. Based on the results obtained, the band gap configuration herein proposed appears to be a prospective strategy for high-performance ultrathin Cu(In,Ga)Se2-based PV cell architecture engineering. By combining this approach with the optimization of the active layer doping, we enhanced the yields of the reference structure from 18.93% for a 2 μm active layer to 23.36% for only 0.5 μm thickness of active layer, that is, an enhancement of 4.4%. The fill factor increased from 73.24 to 81.73%, that is, an additional stability indicator value of 8.5%. The good values of the obtained efficiency and the improvement of the fill factor value are relevant indicators of a stable device. Active layer stacking combined with a stepped band gap profile and doping level optimization is definitely providing new perspectives in thin-film CIGS high-performance PV cell achievement.

“…[31,32] Since the year of 2009, Perovskite solar cells (PSCs) have attracted a great deal of attention from both the scientific and technological community due to their ever-growing PCE, lowcost raw materials, thin-film structures and facile fabrication processes. [20,[33][34][35][36][37][38][39][40][41][42][43] The PCE of single-junction PSCs has grown from the initial 3.8% in the year of 2009 to the latest more than 26%, approaching the theoretical limit efficiency of singlejunction PSCs, [35,43,44] and rivaling other existed PV semiconductors, such as multi(mono)-crystalline Si, [29,30] dye-sensitized, [45,46] gallium arsenide (GaAs), [47,48] copper indium gallium selenide (CIGS), [49,50] as well as quantum dot (QD) SCs. [51,52] However, PSCs still suffer from questionable stability under long-term operation condition, [34,36,41,53,54] rendering PSC commercialization.…”

Over the past decade, the power conversion efficiency (PCE) of perovskite solar cells (PSCs) has experienced a remarkable ascent, soaring from 3.8% in 2009 to a remarkable record of 26.1% in 2023. Many recent approaches for improving PSC performance employ nanophotonic technologies, from light harvesting and thermal management to the manipulation of charge carrier dynamics. Plasmonic nanoparticles (NP) and arrayed dielectric nanostructures have been applied to tailor the light absorption, scattering, and conversion, as well as the heat dissipation within PSCs to improve their PCE and operational stability. In this review, we begin with a concise introduction to define the realm of nanophotonics by focusing on the nanoscale interactions between light and surface plasmons or dielectric photonic structures. We then elaborate on the prevailing strategies that utilize resonance‐enhanced light‐matter interactions for boosting the PCE and stability of PSCs from light trapping, carrier transportation and thermal management perspectives, and discuss the resultant practical applications, such as semi‐transparent photovoltaics (PV), colored PSCs, and smart perovskite windows. Finally, we review the state‐of‐the‐art nanophotonic paradigms in PSCs, and highlight the benefits of these approaches in improving the aesthetic effects and energy‐saving character of PSC‐integrated buildings.This article is protected by copyright.

This report is an approach to form thin-film solar cells on graphite as an alternative electrode for the development of solar cells toward the next generation. From the early stage of development of CZTS, composing of copper (Cu), zinc (Zn), tin (Sn), and sulfur (S), Mo-coated substrates have been used. However, the definition of rare metals in recent years already includes Mo. We focus the graphite as a bottom electrode and the substrate because of its versatility and inexpensive cost. The CZTS precursor was prepared by the RF sputtering method. After that, NaF was deposited by the E-B vapor deposition method to control the Na composition ratio. CZTS films were obtained by gas-phase sulfurization. CZTS solar cells with MgF2/Al/AZO/CdS/CZTS/Graphite structure were prepared. These results suggest the CZTS on the graphite with NaF control shows the potential for realizing the low cost CZTS solar cell.
