A novel immobilized fullerene–single wall carbon nanotube (C60–SWCNT) complex was synthesized via a microwave induced functionalization approach. It has been used as a component of the photoactive layer in a bulk heterojunction photovoltaic cell. As compared to a control device with only C60, the addition of SWCNTs resulted in an improvement of both the short circuit current density JSC and the...
Batteries and fuel cells contain a great potential to back up severe photovoltaic power fluctuations under inclement weather conditions. In this paper comparison between batteries and fuel cells is carried out in detail only for their PV power backup options, so their common attributes and different attributes is discussed. Then, the common and different attributes are compared; accordingly, th...
سلول های خورشیدی مبتنی بر پلیمرها در سال های اخیر به دلیل راحتی تهیه پلیمرها و ارزانی آن ها به شدت مورد توجه قرار گرفته اند. در دهه 1960 مطالعات اساسی بر روی خواص نوری و الکترونیکی مولکول های الی انجام شد و این مطالعات تا دهه 1980 زمانی که مولکول های آلی کوچک با درجه خلوص بالا و ساختار و خواص مناسب در دمای اتاق در قیلم های نازک با استفاده از تکنیک های فاز بخار سنتز شدند ادامه یافت. با گسترش این...
Recently, the anomalous photovoltaic (PV) effect in BiFeO3 (BFO) thin films, which resulted in open circuit voltages (Voc) considerably larger than the band gap of the material, has generated a revival of the entire field of photoferroelectrics. Here, via temperature-dependent PV studies, we prove that the bulk photovoltaic (BPV) effect, which has been studied in the past for many non-centrosym...
Three alkoxy-wrapped push-pull porphyrins were designed and synthesized for dye-sensitized solar cell (DSSC) applications. Spectral, electrochemical, photovoltaic and electrochemical impedance spectroscopy properties of these porphyrin sensitizers were well investigated to provide evidence for the molecular design.
A solar cell or photovoltaic cell is a device which generates electricity directly from visible light. However, their efficiency is fairly low. So, the solar cell costs expensive according to other energy resources products. Several factors affect solar cell efficiency. This paper presents the most important factors that affecting efficiency of solar cells. These effects are cell temperature, M...
