A novel wide bandgap polymer PTZP with Eoptg of 2.01 eV was designed and synthesized. PSCs based on PTZP exhibited high PCE of 11.8%. PCEs of over 10% were obtained with an active layer thickness of 200 nm or an area of 0.81 cm2. PTZP was shown to be a promising conjugated polymer for the fabrication of efficient large area PSCs.

Halide Perovskite

The sun finds a diamond in the rough, which is the organo-metal halide perovskite. Thanks to exceptional optoelectronic characteristics, solar cells employing perovskite demonstrated first a power conversion efficiency (PCE) of 9.7% in the middle of 2012, which rose steeply to an amazing 16% at the end of 2013. Perovskite-based photovoltaics have several advantages over conventional semiconductor p-n junction devices because high efficiency can be achieved from sub-micrometer-thick very cheap perovskite layers that can be formed by solution processing at temperatures below 150°C, rendering the perovskite solar cell versatile in its application. If photo- and thermal stability as well as tolerance to humidity can be achieved, commercial application on the large scale appear to be feasible.
