Abstract

This paper presents an updated study on the technological feasibility of different photovoltaic cells in tropical climates, focusing on the Brazilian Solar Belt, a high-irradiance region. A multicriteria indicator based on Hierarchical Process Analysis (HPA) was developed to evaluate technologies under high temperature, humidity, and irradiation. Crystalline silicon cells (PERC, TOPCon, HJT, IBC), thin films (CdTe, CIGS), and emerging cells (organic, perovskites and tandem) were assessed for efficiency, cost, climate resistance, and degradation. Real climate data and Brazilian field evidence calibrated the model. This work fills a gap in the literature by integrating economic and degradation data into a decision tool focused on Brazil. Cost per watt installed (≈29%) and conversion efficiency (≈18 %) dominated the weights, whereas PID and damp‑heat resistance accounted for less than 3%. The final ranking showed TOPCon as the preferred technology followed by IBC and HJT; PERC, Perovskite and OPVs occupied intermediate positions, while CdTe and CIGS ranked lowest. The results highlight the trade‑off between performance and reliability in hot–humid climates and the need for region‑specific technology choice.
