MORPHOLOGIES AND PERFORMANCE OF ORGANIC SOLAR CELLS USING LOW POLYMERIZATION DEGREE ALTERNATING COPOLYMER

Crystalline low band-gap alternating indolocarbazole and benzothiadiazole-cored oligothiophene copolymer for organic solar cell applications.

A low band-gap alternating copolymer of indolocarbazole and benzothiadiazole-cored oligothiophene demonstrated balanced crystallinity and solubility; a solar cell combining this polymer with PC(61)BM in a preliminary test demonstrated power conversion efficiencies of 3.6%.

Organic and Hybrid Solar Cells Based on Well-Defined Organic Semiconductors and Morphologies

Abstract. Organic and hybrid bulk-heterojunction solar cells are investigated. We describe the synthesis and solar cell characteristics of well-defined functional thiophene dendrimers. Three-dimensional morphologies of the polymer – metal oxide bulk heterojunctions are analysed with electron tomography and are analysed and simulated with stochastic models, to establish the effect of processing ...

Novel semi-random and alternating copolymer hybrid solar cells utilizing CdSe multipods as versatile acceptors.

Hybrid solar cells with tert-butylthiol exchanged CdSe multipod acceptors and novel semi-random P3HTT-DPP and alternating PCDTBT copolymer donors were studied, giving high performance devices with power conversion efficiencies >3%.

Enhance performance of organic solar cells based on an isoindigo-based copolymer by balancing absorption and miscibility of electron acceptor

Comparison of organic solar cells and inorganic solar cells

The fluctuating price of energy, due to a variety of reasons ranging from geo-political constraints to national and international economic issues, and the fact that these energy resources are finite, can be seen as the main incentives to make a transition to a clean energy society. Solar energy is just one of many ways to make this transition a reality, and of the raft of clean energy technolog...
