In addition to multi-junction cells, the implementation of new materials and technologies has significantly contributed to increasing solar cell efficiency. Perovskite solar cells, a newcomer to the photovoltaic market, have garnered considerable attention due to their impressive performance and lower production costs. Since their discovery, perovskite solar cells have rapidly progressed from initial efficiencies of just a few percentage points to over 25% in a short span of time. Their ease of fabrication and potential for integration into flexible substrates open new avenues for solar energy applications, such as building-integrated photovoltaics (BIPV).

2. Brand and Warranty Just like any other product, brand reputation plays a significant role in pricing. Established brands often charge a premium due to their reliability, customer service, and warranties. When purchasing solar panels, consumers should consider the warranty offered, as a longer warranty often indicates better product quality and durability, which can justify a higher price.
