Abstract:

Organic solar cells (OSCs) have gained significant interest as a promising technology for renewable energy. Although the fact that double digit power conversion efficiencies (PCEs, over 10%) and reasonable lifetimes have been reported,the relatively low device performance and stability for larger scale applications is still hindrance OSCs to enter a direct competition with state of the art inorganic photovoltaic technologies.Substantial research and development efforts on materials’ design, morphological control, and novel device architecture design and applications, device stability as well as major mechanisms for power loss in cellsare required to bring the technology to the necessary performance level.In addition, perovskite hybrid solar cells (pero-HSCs) are also demonstrated to be amongst the most promising candidates within the emerging photovoltaic materials with respect to the PCE and inexpensive fabrication.Effects on the controlling of the perovskite crystallization process and the interface engineering preventing recombination losses as well as tandem architecture with multiple solar cells can further reach the promising PCEs of over 20%.

In this contribution, the related design and development of solution-processed OSCs and pero-HSCs are discussed in detail. Moreover, the implications of thin film photovoltaic products fabricatedfrom labto factory (multiple length scales) are analyzed preliminarily.
