Integrated Idealвђђbandgap Perovskite Bulkвђђheterojunction Solarођ Here, the authors report a highly efficient integrated ideal bandgap perovskite bulk heterojunction solar cell (ipbsc) with an inverted architecture, featuring a near infrared (nir) polymer dtbti based bulk heterojunction (bhj) layer atop guanidinium bromide (gabr) modified fa 0.7 ma 0.3 pb 0.7 sn 0.3 i 3 perovskite film as the photoactive. As a result, the solar cell achieves a power conversion efficiency (pce) of 24.27% (certificated value at 23.4% with 0.283 volt voltage loss), currently the recorded efficiency for both ipbscs and pb sn alloyed pscs, and which is over the highest efficiency of perovskite organic tandem solar cell. moreover, the thermal, humidity and long term.
Integrated Ideal Bandgap Perovskite Bulk Heterojunction Solar ођ Here, the authors report a highly efficient integrated ideal‐bandgap perovskite bulk‐heterojunction solar cell (ipbsc) with an inverted architecture, featuring a near infrared (nir) polymer dtbti‐based bulk‐heterojunction (bhj) layer atop guanidinium bromide (gabr)‐modified fa0.7ma0.3pb0.7sn0.3i3 perovskite film as the photoactive layer. the ipbsc shows cascade‐like energy level. Perovskite organic tandem solar cells. organic solar cells (oscs) are an attractive option for next generation photovoltaics due to their low cost, tunable optical properties, solution. Moreover, dye sensitized solar cells (dsscs) and organic compound solar cells show lower pce (<14.3% for the former and 16% for the latter) than si based solar cells. [13, 14] thus, the next generation solar cells are required to be low cost, high efficiency, and environmentally benign. in recent years, perovskite solar cells (pscs) have. Our study employs a novel ultraviolet cured ionogel electrolyte to prevent moisture induced degradation of the perovskite layer in integrated photorechargeable system, enabling perovskite solar cells to achieve maximum power conversion efficiencies and facilitating the monolithic design of the system with minimal energy loss.

Interface modification was applied in integrated perovskite bulk heterojunction solar cells, leading to improved carrier extraction, suppressed charge recombination, and enhanced photovoltaic performance which was among the highest reported efficiencies of integrated perovskite bhj solar cells so far. download : download high res image (307kb). Currently, the highest certified energy conversion efficiencies of perovskite cells are 25.5% on 0.1 cm 2, 9,26 22.6% on 1 cm 2, 27,28 and 17.9% on 804 cm 2, 28 further increasing power to weight ratios. for solar glazing, the weight of the perovskite cells is negligible. additional weight will only come from the electrical wiring.
