	1	Enhanced thermal stability of organic solar cells comprising ternary D-D-A bulk-heterojunctions显示文摘Ternary absorber blends have recently been identified as promising concepts to spectrally broaden the absorption of organic bulkheterojunction solar cells and hence to improve their power conversion efficiencies.In this work,we demonstrate that D-D-A ternary blends comprising two donor polymers and the acceptor PC61BM can also significantly enhance the thermal stability of the solar cell.Upon harsh thermal stress at 120°C for 2 h,the ternary solar cells show only a minor relative deterioration of 10%.Whereas the polymer/fullerene blend PTB7-Th:PC61BM is rather unstable under these conditions,its degradation was efficiently suppressed by incorporating the near infrared-absorbing polymer PDTP–DFBT.Spectroscopic ellipsometry investigations and an effective medium analysis of the ternary absorber blend revealed that the domain conformation in presence of PDTP–DFBT remains stable whereas the domain conformation changes in its absence.The ternary PTB7-Th:PDTP–DFBT:PC61BM solar cells yield thermally stable power conversion efficiencies of up to 6%.

	2	Fully printed origami thermoelectric generators for energy-harvesting显示文摘Energy-harvesting from low-temperature environmental heat via thermoelectric generators(TEG)is a versatile and maintenancefree solution for large-scale waste heat recovery and supplying renewable energy to a growing number of devices in the Internet of Things(IoT)that require an independent wireless power supply.A prerequisite for market competitiveness,however,is the costeffective and scalable manufacturing of these TEGs.Our approach is to print the devices using printable thermoelectric polymers and composite materials.We present a mass-producible potentially low-cost fully screen printed flexible origami TEG.Through a unique two-step folding technique,we produce a mechanically stable 3D cuboidal device from a 2D layout printed on a thin flexible substrate using thermoelectric inks based on PEDOT nanowires and a TiS2:Hexylamine-complex material.We realize a device architecture with a high thermocouple density of 190 per cm2 by using the thin substrate as electrical insulation between the thermoelectric elements resulting in a high-power output of 47.8μWcm^(−2)from a 30 K temperature difference.The device properties are adjustable via the print layout,specifically,the thermal impedance of the TEGs can be tuned over several orders of magnitudes allowing thermal impedance matching to any given heat source.We demonstrate a wireless energy-harvesting application by powering an autonomous weather sensor comprising a Bluetooth module and a power management system.
