Solar energy is no longer just about cost! While reading a paper that discusses the cost analysis of perovskite–organic tandem solar cells (https://doi.org/10.1002/solr.20250), it was particularly interested in the economic aspects. The study reports promising figures: ~$0.49/W module cost and ~4.8¢/kWh levelized cost of electricity (LCOE), based on modeling assumptions. Although these values are theoretical and depend on system assumptions, they highlight the strong potential for cost reduction in next-generation solar technologies. What matters most is not only the numbers, but the conditions behind them. Viability is strongly linked to achieving a balance between: • High efficiency (~25%) • Long operational lifetime (~25 years) • Low degradation rates In other words, stability is as important as performance. This made me reflect more broadly on energy systems. In uncertain environments, energy is not only an economic parameter—it becomes a matter of continuity. Conventional systems are centralized, fuel-dependent, and vulnerable to disruption. Solar energy offers a different structure—decentralized, distributed, and more resilient. From a practical perspective, the contrast in cost becomes significant in crisis conditions. In places like Gaza, electricity from conventional fuels can reach extreme levels (reported up to ~$8/kWh), while solar, once installed, remains at only a few cents per kWh. The value of solar energy is not only in cost reduction, but in reliability under uncertainty. It is not just a sustainable technology— it is a strategic asset for resilience, independence, and continuity.
