A flexible back-contact perovskite solar micro-module

Abstract

Back-contact PSCs are fabricated by depositing charge-selective electrodes and MAPbI3 into micron-sized polymeric grooves, micro-modules are formed by serially-connecting grooves.

The nature of the methylamine–MAPbI3 complex: fundamentals of gas-induced perovskite liquefaction and crystallization

“…15 Consequentially, manufacturing the photo-absorber layer of a PV device using methylamine-perovskite interaction establishing itself as a promising, cost-effective approach, that can be implemented on a large scale module production. [16][17][18] The question what stands behind the observed mechanism of perovskite liquefaction was already raised in previous reports. Zhou et al supposed that the lone-electron pair in the nitrogen (N) atom of methylamine gas interacts with PbI 6 octahedra, which leads to a liqueed state.…”

Theoretical study of building-integrated photovoltaics based on perovskite single junction and perovskite/silicon tandem solar cells

“…To estimate the hourly photovoltaic energy gains, the experimental angle-dependent performance of the PSCs (Ball et al., 2015) and the PSTs (Hörantner and Snaith, 2017) is considered. According to the measurements, the maximum cell efficiencies under vertical irradiation are assumed to be 7.3% (Wong-Stringer et al., 2019), 18.5% (Jang et al., 2019), and 22.6% (Kamino et al., 2019) for the flexible PSCs, the classic PSCs and the PSTs, respectively. The cell efficiency is assumed to be independent with either the solar spectrum or the solar intensity in our first study here.…”

Current advancements on charge selective contact interfacial layers and electrodes in flexible hybrid perovskite photovoltaics

“…These materials can also be coated using low-cost solution processing methods but the performance was limited mainly by the increased sheet resistance and lower transmittance in comparison with the ITOs. There were also attempts to fabricate the back-contact PSCs that were designed to reduce the contact resistance to influence the PSC performance [261]. Many hybrids or composite electrodes (e.g.…”

“…Hence, suitable contact engineering of these types of advanced emerging nanostructured materials would pave the way for the new design and development of other derived interface layers. In the case of back contact electrodes for use in reliable flexible substrates, a mechanically robust and conductive electrode is highly warranted with reasonable reproducibility and minimal variation in the performance distribution [241,245,261,286,287].…”
