Solution-processed bulk-heterojunction solar cells have gained serious attention during the last few years and are becoming established as one of the future photovoltaic technologies for low-cost power production. This article reviews the highlights of the last few years, and summarizes today's state-of-the-art performance. An outlook is given on relevant future materials and technologies that have the potential to guide this young photovoltaic technology towards the magic 10% regime. A cost model supplements the technical discussions, with practical aspects any photovoltaic technology needs to fulfil, and answers to the question as to whether low module costs can compensate lower lifetimes and performances.

    • "Bowl-shaped polyaromatic hydrocarbons (PAHs) have emerged in recent years as promising new materials for important technological applications: batteries, optoelectronic devices, photoactive switches and chemical sensors. These curved polyarenes (often called p-bowls) are excellent electron acceptors, comparable to planar PAHs [1] [2] and fullerenes [3] [4], and could serve as key anode components in rechargeable Li-ion batteries. Corannulene, the smallest non-planar fragment of C 60 fullerene [5] [6], was shown to exhibit high degree of lithium intercalation upon step-wise reduction [7] [8] [9] [10] and corannulene-based anode materials have demonstrated a high reversible lithium capacity, almost twice as high as that of fully lithiated graphite [11] [12].

    ABSTRACT: First-principles calculations combined with the Boltzmann transport theory are used to investigate the electronic transport properties of four members of the extended family of indenocorannulene molecular crystals. The results for the electrical conductivity suggest that all indenocorannulene derivatives should exhibit transport characteristics significantly improved compared to the parent corannulene. In particular, the transport properties of 1,2,4-triindenocorannulene crystal are found to be comparable for electron doping and likely surpass for hole doping the values achievable in sumanene, assuming the same carrier lifetimes. The findings point to a large sensitivity of the charge-carrier conductivity to the size as well as stacking direction of the carbon-rich π-bowls and indicate that this class of corannulene derivatives can provide new structural motifs that can be further tuned to achieve high-performance materials for organic electronic devices.

    • "In the past decades, polymer solar cells (PSCs) have been of great interest for the development of renewable energy technologies because of the advantages of low cost, light weight and flexibility [1] [2] [3] [4]. Very recently, tandem PSCs have afforded power-conversion efficiencies (PCEs) exceeding 10%, showing a promising potential for commercial applications [5] [6]. "

    ABSTRACT: A series of fulleropyrrolidine derivatives (FPx, x = 1–8) with alternating N-phenyl or N-methyl group were prepared as acceptors for polymer solar cells (PSCs) with the purpose of investigating the effect of N-substitutions on the photovoltaic properties of fullerene materials. More importantly, the morphology studies by means of atomic force microscopy (AFM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and space charge limited current (SCLC) measurements revealed that FP1 with N-phenyl group possessed not only appropriate miscibility with P3HT but also high electron mobility, which may account for its optimal photovoltaic properties.

    • "Dye-sensitized (DSSC) and organic solar cells (OPVs) have gained appreciable interest for their special properties, which make them ideal candidates for their integration in everyday life. Their many interesting properties such as low fabrication cost [20], easy scalability, simple manufacturing process [21] [22], low material consumption, sensitivity to low light levels and ease of use for large area applications [23] [24] [25] [26] [27] [28] [29] [30] [31] [32] [33] [34] make them ideal candidates for use as energy windows [35] [36]. 2.2.1.

    ABSTRACT: In the frame of zero-energy buildings, the integration of renewable energy sources along with energy saving strategies must be the target. PV glazing is an innovative technology which apart from electricity production can reduce energy consumption in terms of cooling, heating and artificial lighting. Thus, it mitigates the pollution and reduces associated costs. In this context, the latest achievements of semi-transparent PV windows and their impact on buildings energy performance and occupants comfort are reviewed.
